  text: Luminous broad Hα emission and red rest-optical spectral energy distributions
    (SEDs) are the hallmark of compact little red dots (LRDs), implying highly attenuated
    dusty starbursts and/or obscured active galactic nuclei (AGN). However, the lack
    of observed far-infrared (FIR) emission has proved difficult to reconcile with
    the implied attenuated luminosity in these models. Here, we utilize deep new Atacama
    Large Millimeter/submillimeter Array imaging, new and existing JWST/MIRI imaging,
    and archival Spitzer/Herschel imaging of two of the rest-optically brightest LRDs
    (z = 3.1 and z = 4.47) to place the strongest constraints on the IR luminosity
    in LRDs to date. The detections at λrest = 1–4 μm imply flat slopes in the rest-IR,
    ruling out a contribution from hot (T ≳ 500 K) dust. Similarly, FIR nondetections
    rule out any appreciable cold (T ≲ 75 K) dust component. Assuming energy balance,
    these observations are inconsistent with the typical FIR dust emission of dusty
    starbursts and quasar tori, which usually show a mixture of cold and hot dust.
    Additionally, our [C ii] nondetections rule out typical dusty starbursts. We compute
    empirical maximum IR SEDs and find that both LRDs must have log(LIR/L ) 12.2 at
    the 3σ level. These limits are in tension with the predictions of rest-optical
    spectrophotometric fits, be they galaxy-only, AGN-only, or composite. It is unlikely
    that LRDs are highly dust-reddened intrinsically blue sources with a dust temperature
    distribution that conspires to avoid current observing facilities. Rather, we
    favor an intrinsically redder LRD SED model that alleviates the need for strong
    dust attenuation.

  text: "Compact, star-forming galaxies with high star formation rate surface densities
    (ΣSFR) are often efficient Lyman continuum (LyC) emitters at z ≤ 4.5, likely because
    intense stellar feedback creates low-density channels that allow photons to escape.
    Irregular or disturbed morphologies, such as those resulting from mergers, can
    also facilitate LyC escape by creating anisotropic gas distributions. We investigated
    the influence of galaxy morphology on LyC production and escape at redshifts 5
    ≤ z ≤ 7 using observations from various James Webb Space Telescope (JWST) surveys.
    Our sample consists of 436 sources, which are predominantly low-mass (∼10^8.15
    M\f), star-forming galaxies with ionizing photon efficiency (ξion) values consistent
    with canonical expectations. Since direct measurements of fesc are not possible
    during the Epoch of  Reionization (EoR), we predicted fesc for high-redshift galaxies
    by applying survival analysis to a subsample of LyC emitters from the Low-Redshift
    Lyman Continuum Survey (LzLCS), selected to be direct analogs of reionization-era
    galaxies. We find that these galaxies exhibit, on average, modest predicted escape
    fractions (∼0.04). In addition, we evaluated the correlation between morphological
    features and LyC emission. Our findings indicate that neither ξion nor the predicted
    fesc values show a significant correlation with the presence of merger signatures.
    This suggests that in low-mass galaxies at z ≥ 5, strong morphological disturbances
    are not the primary mechanism driving LyC emission and leakage. Instead, compactness
    and star formation activity likely play a more pivotal role in regulating LyC
    escape. "

  text: 'Detecting the first generation of stars, Population III (Pop III), has been
    a long-standing goal in astrophysics, yet they remain elusive even in the JWST
    era. Here we present a novel NIRCam-based selection method for Pop III galaxies,
    and carefully validate it through completeness and contamination simulations.
    We systematically search ≃ 500 arcmin2 across JWST legacy fields for Pop III candidates,
    including GLIMPSE, which, assisted by gravitational lensing, has produced JWST’s
    deepest NIRCam imaging thus far. We discover one promising Pop III galaxy candidate
    (GLIMPSE-16043) at z=6.50 -0.24 +0.03, a moderately lensed galaxy (µ = + 2.9 -0.2
    +0.1) with an intrinsic UV magnitude of MUV= -15.89 -0.14 +0.12. It exhibits key
    Pop III features: strong Hα emission (rest-frame EW 2810 ± 550 Å); a Balmer jump;
    no dust (UV slope β = −2.34 ± 0.36); and undetectable metal lines (e.g., [O III];
    [O III]/Hβ < 0.44), implying a gas-phase metallicity of Zgas/Z⊙ < 0.5%. These
    properties indicate the presence of a nascent, metal-deficient young stellar population
    (<5 Myr) with a stellar mass of ≃105 M⊙. Intriguingly, this source deviates significantly
    from the extrapolated UV–metallicity relation derived from recent JWST observations
    at z = 4–10, consistent with UV enhancement by a top-heavy Pop III initial mass
    function or the presence of an extremely metal-poor active galactic nucleus. We
    also  derive the first observational constraints on the Pop III UV luminosity
    function at z ≃ 6–7. The volume density of GLIMPSE-16043 (≈10^−4 cMpc−3) is in
    excellent agreement with theoretical predictions, independently reinforcing its
    plausibility. This study demonstrates the power of our novel NIRCam method to
    finally reveal distant galaxies even more pristine than the Milky Way’s most metal-poor
    satellites, thereby promising to bring us closer to the first generation of stars
    than we have ever been before.'

  text: JWST observations have unveiled faint active galactic nuclei (AGNs) at high
    redshift that provide insights into the formation of supermassive black holes
    (SMBHs). However, disentangling their stellar from AGN light is challenging. Here,
    we use an empirical approach to infer the average stellar mass of five faint broad-line
    (BL) Hα emitters at z = 4–5 with BH masses ≈6 × 10^6 M⊙, with a method independent
    of their spectral energy distribution (SED). We use the deep JWST/NIRcam grism
    survey “All the Little Things” to measure the overdensities around BL-Hα emitters
    and around a spectroscopic reference sample of ∼300 galaxies. In our reference
    sample, we find that megaparsec-scale overdensity correlates with stellar mass.
    Their large-scale environments suggest that BL-Hα emitters are hosted by galaxies
    with stellar masses ≈5 × 10^7 M⊙, ≈40 times lower than those inferred from galaxy-only
    SED fits. Adding measurements around more luminous z ≈ 6 AGNs, we find tentative
    correlations between line width, BH mass, and the overdensity, suggestive of a
    steep BH to halo mass relation. The main implications are (1) when BH masses are
    taken at face value, we confirm extremely high BH to stellar mass ratios of ≈10%,
    (2) the galaxies of low stellar mass that host growing SMBHs are in tension with
    typical hydrodynamical simulations, except those without feedback, (3) a 1% duty
    cycle implied by the host mass hints at super-Eddington accretion, (4) the masses
    are at odds with an interpretation of the line broadening in terms of high stellar
    density, (5) our results imply a luminosity-dependent diversity of galaxy masses,
    environments, and SEDs among AGN samples.

  text: "We report the detection of a 13σ Hα emission line from HDF850.1 at z = 5.188
    ± 0.001 using the FRESCO (First Reionization Era SpectroscopicallyComplete Observations)
    NIRCam F444W grism observations. Detection of Hα in HDF850.1 is noteworthy, given
    its high far-infrared (IR) luminosity, substantial dust obscuration, and the historical
    challenges in deriving its redshift.\r\nHDF850.1 shows a clear detection in the
    F444W imaging data, distributed between a northern and southern component, mirroring
    that seen in [C II] from the Plateau de Bure Interferometer. Modelling the spectral
    energy distribution of each component separately, we find that the northern component
    has a higher mass, star formation rate (SFR), and dust extinction than the southern
    component. The observed Hα emission appears to arise entirely from the less-obscured
    southern component and shows a similar \x04v∼ + 130 km s −1 velocity offset to
    that seen for [C II] relative to the source systemic redshift. Leveraging Hα-derived
    redshiftsfrom FRESCO observations, we find that HDF850.1 isforming in one of the
    richest environments identified to date at z > 5, with 100 z = 5.17–5.20 galaxies
    distributed across 13 smaller structures and a ∼(15 cMpc)3 volume. Based on the
    evolution of analogous structures in cosmological simulations, the z = 5.17–5.20
    structures seem likely to collapse into\r\na single > 1014M cluster by z ∼ 0.
    Comparing galaxy properties forming within this overdensity with those outside,
    we find the masses, SFRs, and UV luminosities inside the overdensity to be clearly
    higher. The prominence of Hα line emission from HDF850.1 and other known highly
    obscured z > 5 galaxies illustrates the potential of NIRCam-grism programs to
    map both\r\nthe early build-up of IR-luminous galaxies and overdense structures."

  text: "Causal discovery from observational data holds great promise, but existing
    methods rely on strong assumptions about the underlying causal structure, often
    requiring full observability of all relevant variables. We tackle these challenges
    by leveraging the score function ∇logp(X)\r\n of observed variables for causal
    discovery and propose the following contributions. First, we generalize the existing
    results of identifiability with the score to additive noise models with minimal
    requirements on the causal mechanisms. Second, we establish conditions for inferring
    causal relations from the score even in the presence of hidden variables; this
    result is two-faced: we demonstrate the score’s potential as an alternative to
    conditional independence tests to infer the equivalence class of causal graphs
    with hidden variables, and we provide the necessary conditions for identifying
    direct causes in latent variable models. Building on these insights, we propose
    a flexible algorithm for causal discovery across linear, nonlinear, and latent
    variable models, which we empirically validate."

  text: 'Hypertrace logic is a sorted first-order logic with separate sorts for time
    and execution traces. Its formulas specify hyperproperties, which are properties
    relating multiple traces. In this work, we extend hypertrace logic by introducing
    trace quantifiers that range over the set of all possible traces. In this extended
    logic, formulas can quantify over two kinds of trace variables: constrained trace
    variables, which range over a fixed set of traces defined by the model, and unconstrained
    trace variables, which can be assigned to any trace. In comparison, hyperlogics
    such as HyperLTL have only constrained trace quantifiers. We use hypertrace logic
    to study how different quantifier patterns affect the decidability of the satisfiability
    problem. We prove that hypertrace logic without constrained trace quantifiers
    is equivalent to monadic second-order logic of one successor (S1S), and therefore
    satisfiable, and that the trace-prefixed fragment (all trace quantifiers precede
    all time quantifiers) is equivalent to HyperQPTL. Moreover, we show that all hypertrace
    formulas where the only alternation between constrained trace quantifiers is from
    an existential to a universal quantifier are equisatisfiable to formulas without
    constraints on their trace variables and, therefore, decidable as well. Our framework
    allows us to study also time-prefixed hyperlogics, for which we provide new decidability
    and undecidability results.'

  text: Fairness in AI is traditionally studied as a static property evaluated once,
    over a fixed dataset. However, real-world AI systems operate sequentially, with
    outcomes and environments evolving over time. This paper proposes a framework
    for analysing fairness as a runtime property. Using a minimal yet expressive model
    based on sequences of coin tosses with possibly evolving biases, we study the
    problems of monitoring and enforcing fairness expressed in either toss outcomes
    or coin biases. Since there is no one-size-fits-all solution for either problem,
    we provide a summary of monitoring and enforcement strategies, parametrised by
    environment dynamics, prediction horizon, and confidence thresholds. For both
    problems, we present general results under simple or minimal assumptions. We survey
    existing solutions for the monitoring problem for Markovian and additive dynamics,
    and existing solutions for the enforcement problem in static settings with known
    dynamics.

  text: Neural certificates have emerged as a powerful tool in cyber-physical systems
    control, providing witnesses of correctness. These certificates, such as barrier
    functions, often learned alongside control policies, once verified, serve as mathematical
    proofs of system safety. However, traditional formal verification of their defining
    conditions typically faces scalability challenges due to exhaustive state-space
    exploration. To address this challenge, we propose a lightweight runtime monitoring
    framework that integrates real-time verification and does not require access to
    the underlying control policy. Our monitor observes the system during deployment
    and performs on-the-fly verification of the certificate over a lookahead region
    to ensure safety within a finite prediction horizon. We instantiate this framework
    for ReLU-based control barrier functions and demonstrate its practical effectiveness
    in a case study. Our approach enables timely detection of safety violations and
    incorrect certificates with minimal overhead, providing an effective but lightweight
    alternative to the static verification of the certificates.

  text: Formal verification provides assurances that a probabilistic system satisfies
    its specification—conditioned on the system model being aligned with reality.
    We propose alignment monitoring to watch that this assumption is justified. We
    consider a probabilistic model well aligned if it accurately predicts the behaviour
    of an uncertain system in advance. An alignment score measures this by quantifying
    the similarity between the model’s predicted and the system’s (unknown) actual
    distributions. An alignment monitor observes the system at runtime; at each point
    in time it uses the current state and the model to predict the next state. After
    the next state is observed, the monitor updates the verdict, which is a high-probability
    interval estimate for the true alignment score. We utilize tools from sequential
    forecasting to construct our alignment monitors. Besides a monitor for measuring
    the expected alignment score, we introduce a differential alignment monitor, designed
    for comparing two models, and a weighted alignment monitor, which permits task-specific
    alignment monitoring. We evaluate our monitors experimentally on the PRISM benchmark
    suite. They are fast, memory-efficient, and detect misalignment early.

  text: We propose a monitoring approach for hyperproperties where the system’s observations
    range over infinite domains. The specifications are given as formulas of symbolic
    hypernode logic, an extension of earlier versions of hypernode logic that supports
    events with data. We demonstrate how to translate terms of symbolic hypernode
    logic into multi-tape symbolic transducers and we present a monitoring algorithm
    for universally quantified formulas that is based on this translation. We evaluate
    our approach against the previous approach for monitoring hypernode logic, and
    we also compare it to other monitors for hyperproperties.

  text: The relation between the masses of supermassive black holes (SMBHs) and their
    host galaxies encodes information on their mode of growth, especially at the earliest
    epochs. The James Webb Space Telescope (JWST) has opened such investigations by
    detecting the host galaxies of active galactic nuclei (AGN) and more luminous
    quasars within the first billion years of the Universe (z ≳ 6). Here, we evaluate
    the relation between the mass of SMBHs and the total stellar mass of their host
    galaxies using a sample of nine quasars at 6.18 ≤ z ≤ 6.4 from the Subaru High-z
    Exploration of Low-luminosity Quasars survey with NIRCam and NIRSpec observations.
    We find that the observed location of these quasars in the SMBH–galaxy mass plane
    (logMBH/M 8–9; logM*/M 9.5–11) is consistent with a nonevolving intrinsic mass
    relation with dispersion (0.80 +0.23 -0.28 dex) higher than the local value (∼0.3–0.4
    dex) of their more massive descendants. Our analysis is based on a forward model
    of systematics and includes a consideration of the impact of selection effects
    and measurement uncertainties with an assumption on the slope of the mass relation.
    While degeneracies between parameters persist, the best-fit solution has a reasonable
    AGN fraction (2.3%) of galaxies at z ∼ 6 with an actively growing UV-unobscured
    black hole. In particular, models with a substantially higher normalisation in
    MBH would require an unrealistically low intrinsic dispersion (∼0.22 dex). Consequently,
    our results predict a large population of AGN at lower black hole masses, as are
    now just starting to be discovered in focused efforts with JWST.

  text: The multimessenger combination of gravitational waves (GWs) from merging massive
    black hole binaries (MBHBs) and the electromagnetic (EM) counterpart from the
    surrounding circumbinary disc (CBD) will open avenues to new scientific pursuits.
    In order to realize this science, we need to correctly localize the host galaxy
    of the merging MBHB. Multiwavelength, time-dependent EM signatures can greatly
    facilitate the identification of the unique EM counterpart among many sources
    in LISA’s localization volume. To this end, we studied merging unequal-mass MBHBs
    embedded in a CBD using high-resolution 2D simulations, with a $\Gamma$-law equation of
    state, incorporating viscous heating, shock heating, and radiative cooling. We
    simulate each binary starting from before it decouples from the CBD until just
    after the merger. We compute EM signatures and identify distinct features before,
    during, and after the merger. We corroborate previous findings of a several orders
    of magnitude drop in the thermal X-ray luminosity near the time of merger, but
    with delayed timing compared to an equal-mass system. The source remains X-ray
    dark for hours post-merger. Our main results are a potential new signature of
    a sharp spike in the thermal X-ray emission just before the tell-tale steep drop
    occurs. This feature may further help to identify EM counterparts of LISA’s unequal
    MBHBs before merger without the need for extensive pre-merger monitoring. Additionally,
    we find a role-reversal in which the primary out-accretes the secondary during
    late inspiral, which may diminish signatures originating from Doppler modulation.

  text: We present a study of the late-time interaction between supermassive black
    hole binaries and retrograde circumbinary disks during the period of gravitational
    wave-driven inspiral. While mergers in prograde disks have received extensive
    study, retrograde disks offer distinct dynamics that could promote mergers and
    produce unique observational signatures. Through 2D numerical hydrodynamical simulations,
    we explore the process of binary-disk decoupling, where the binary’s orbital decay
    rate is faster than the disk’s viscous response rate. We find the point of decoupling
    to be comparable in prograde and retrograde disks, suggesting that any associated
    electromagnetic (EM) signatures will be produced at comparable times preceding
    the merger. However, we find smaller central cavities for retrograde disks, likely
    leading to higher-frequency EM emissions and shorter postmerger rebrightening
    timescales compared to their prograde counterparts. Retrograde disks form intrabinary
    bridges, which are prone to instabilities when the viscosity is low. These instabilities
    manifest as quasiperiodic flares in the accretion rate, which may produce distinctive
    EM signatures for retrograde disks.

  text: The advent of the James Webb Space Telescope (JWST) has opened new horizons
    in the study of quasar host galaxies during the reionization epoch (z > 6). Building
    upon our previous initial measurements of stellar light from two quasar host galaxies
    at these redshifts, we now report the detection of the stellar light from the
    full Cycle 1 sample of 12 distant moderate-luminosity quasar (M1450 > −24 mag)
    host galaxies at z > 6 from the Hyper Suprime-Cam Subaru Strategic Program. Using
    JWST/NIRCam observations at 1.5 and 3.6 μm combined with 2D image decomposition
    analysis, we successfully detect the host galaxies in 11 of the 12 targets, underscoring
    the high detection rates achievable with moderate-luminosity quasars. Based on
    two-band photometry and spectral energy distribution fitting, we find that our
    host galaxies are massive, with log M*/M⊙ = 9.5–11.0. The effective radii range
    from 0.6 to 3.2 kpc, comparable to the sizes of inactive galaxies with similar
    masses at z ∼ 6 as measured with imaging from COSMOS-Web. Intriguingly, the two
    quasar hosts with post-starburst features, which reside at the high-mass end of
    our sample and exhibit relatively compact morphologies, have similar size and
    stellar mass surface densities to quiescent galaxies at z ∼ 4–5. These findings
    suggest that the so-called galaxy compaction scenario is already in place at the
    reionization epoch, in which gas inflows during starburst phases drive centrally
    concentrated star formation followed by rapid quenching, bridging the structural
    transition of massive galaxies from relatively extended star-forming disks to
    compact quiescent systems.

  text: "The thermal Sunyaev-Zel’dovich effect (tSZ) is a sensitive probe of cosmology,
    as it traces the abundance of galaxy clusters and groups in the late-time Universe.
    Upcoming cosmic microwave background experiments such as the Simons Observatory
    (SO) and CMB-S4 will provide low-noise and high-resolution component-separated
    tSZ maps covering a large sky fraction. The tSZ signal is highly non-Gaussian;
    therefore, higher-order statistics are needed to optimally extract information
    from these maps. In this work, we study the cosmological constraining power of
    several tSZ statistics—Minkowski functionals (MFs), peaks, minima, and moments—that
    have yielded promising results in capturing non-Gaussian information from other
    cosmological data. Using a large suite of halo-model-based tSZ simulations with
    varying Ω\U0001D450 and \U0001D70E8 (154 cosmologies and over 800,000 maps, each
    10.5×10.5  deg2), we show that by combining these observables, we can achieve
    \ ≈29 × tighter constraints compared to using the tSZ power spectrum alone in
    an idealized noiseless case, with the MFs dominating the constraints. We show
    that much of the MF constraining power arises from halos below the detection threshold
    of cluster surveys, suggesting promising synergies with cluster-count analyses.
    Finally, we demonstrate that these statistics have the potential to deliver tight
    constraints even in the presence of noise. For example, using post-component-separation
    tSZ noise expected for SO, we obtain  ≈1.6 × and  ≈1.8 × tighter constraints than
    the power spectrum with MFs and all statistics combined, respectively. We show
    that the constraints from MFs approach the noiseless case for white-noise levels
    ≲1  \U0001D707⁢K−arcmin."

  text: Subparsec supermassive black hole (SMBH) binaries are expected to be common
    in active galactic nuclei as a result of the hierarchical buildup of galaxies
    via mergers. While direct evidence for these compact binaries is lacking, a few
    hundred candidates have been identified, most based on the apparent periodicities
    of their optical light curves. Since these signatures can be mimicked by active
    galactic nuclei red noise, additional evidence is needed to confirm their binary
    nature. Recurring self-lensing flares, occurring whenever the two BHs are aligned
    with the line of sight within their Einstein radii, have been suggested as additional
    binary signatures. Furthermore, in many cases, lensing flares are also predicted
    to contain a “dip,” whenever the lensed SMBH’s shadow is comparable in angular
    size to the binary’s Einstein radius. This feature would unambiguously confirm
    binaries and additionally identify SMBH shadows that are spatially unresolvable
    by high-resolution Very Long Baseline Interferometry (VLBI). Here we estimate
    the number of quasars for which these dips may be detectable by Legacy Survey
    of Space and Time (LSST) by extrapolating the quasar luminosity function to faint
    magnitudes and assuming that SMBH binaries are randomly oriented and have mass
    ratios following those in the Illustris simulations. Under plausible assumptions
    about quasar lifetimes, binary fractions, and Eddington ratios, we expect tens
    of thousands of detectable flares, of which several dozen contain measurable dips.

  text: "The early growth of black holes (BHs) in atomic-cooling haloes is likely
    influenced by feedback on the surrounding gas. While the effects of radiative
    feedback are well-documented, mechanical feedback, particularly from active galactic
    nucleus (AGN) jets, has been comparatively less explored. Building on our previous
    work that examined the growth of a 100 M BH in a constant density environment
    regulated by AGN jets, we expand the initial BH mass range from 1 to 104 M and
    adopt a more realistic density profile for atomic-cooling haloes. We reaffirm
    the validity of our analytic models for jet cocoon propagation and feedback regulation.
    We identify several critical radii – namely, the terminal radius of jet cocoon
    propagation, the isotropization radius of the jet cocoon, and the core radius
    of the atomic-cooling halo – that are crucial in determining BH growth given specific
    gas properties and jet feedback parameters. In a significant portion of the parameter
    space, our findings show that jet feedback substantially disrupts the halo’s core
    during the initial feedback episode, preventing BH growth beyond 104 M.\r\nConversely,
    conditions characterized by low jet velocities and high gas densities enable sustained
    BH growth over extended periods. We provide a prediction for the BH mass growth
    as a function of time and feedback parameters. We found that, to form a supermassive
    BH (> 106 M) within 1 Gyr entirely by accreting gas from an atomic-cooling halo,
    the jet energy feedback\r\nefficiency must be  10−4M˙ BHc2 even if the seed BH
    mass is 104 M."

  text: The brightest steady sources of radiation in the universe, active galactic
    nuclei (AGNs), are powered by gas accretion on to a central supermassive black
    hole (SMBH). The large sizes and accretion rates implicated in AGN accretion discs
    are expected to lead to gravitational instability and fragmentation, effectively
    cutting off mass inflow to the SMBH. Radiative feedback from disc-embedded stars
    has been invoked to yield marginally stable, steady-state solutions in the outer
    discs. Here, we examine the consequences of this star formation with a semi-analytical
    model in which stellar-mass black hole (sBH) remnants in the disc provide an additional
    source of stabilizing radiative feedback. Assuming star formation seeds the embedded
    sBH population, we model the time-evolving feedback from both stars and the growing
    population of accreting sBHs. We find that in the outer disc, the luminosity of
    the sBHs quickly dominates that of their parent stars. However, because sBHs consume
    less gas than stars to stabilize the disc, the presence of the sBHs enhances the
    mass flux to the inner disc. As a result, star formation persists over the lifetime
    of the AGN, damped in the outer disc, but amplified in a narrow ring in the inner
    disc. Heating from the embedded sBHs significantly modifies the disc’s temperature
    profile and hardens its spectral energy distribution, and direct emission from
    the sBHs adds a new hard X-ray component.

  text: Recent hydrodynamical simulations have shown that circumbinary gas disks drive
    the orbits of massive binary black holes (BHs) to become eccentric, even when
    general relativistic (GR) corrections to the orbit are significant. Here, we study
    the GR apsidal precession of eccentric equal-mass massive binary BHs in circumbinary
    disks via two-dimensional hydrodynamical simulations. We perform a suite of simulations
    comparing precessing and nonprecessing binaries across a range of eccentricities,
    semimajor axes, and precession rates. We find that the GR precession of the binary’s
    semimajor axis can introduce a dominant modulation in the binary’s accretion rate
    and the corresponding high-energy electromagnetic light curves. We discuss the
    conditions under which this occurs and its detailed characteristics and mechanism.
    Finally, we discuss the potential to observe these precession signatures in electromagnetic-
    and gravitational-wave observations, as well as the precession signal’s unique
    importance as a potential tool to constrain the mass, eccentricity, and semimajor
    axis of binary merger events.
