Although the signal is too weak to detect in individual galaxies, we analyze the feasibility of its statistical detection via stacking CMB data on many galaxies for which the spin orientation can be estimated spectroscopically. We use an “optimistic” model, in which fully ionized atmospheres contain the cosmic baryon fraction and spin at the halo’s circular velocity 𝑣circ, and a more realistic model, based on hydrodynamical simulations, with multiphase atmospheres spinning at a fraction of 𝑣circ. We incorporate realistic noise estimates into our analysis. Using low-redshift galaxy properties from the MaNGA spectroscopic survey (with median halo mass of 6.6×1011 𝑀⊙), and CMB data quality from Planck, we find that a 3𝜎 detection would require a few×104 galaxies, even in the optimistic model. This is too high for current surveys, but upcoming higher-angular resolution CMB experiments will significantly reduce the requirements: stacking CMB data on galaxy spins in a ∼10 deg2 can rule out the optimistic models, and ≈350 deg2 will suffice for a 3𝜎 detection with ACT. As a proof-of-concept, we stacked Planck data on the position of ≈2,000 MaNGA galaxies, aligned with the galaxies’ projected spin, and scaled to their halos’ angular size. We rule out average temperature dipoles larger than ≈1.9 𝜇K around field spiral galaxies.","lang":"eng"}],"article_type":"original","publication_status":"published","day":"10","oa_version":"Preprint","external_id":{"arxiv":["1909.04690"]},"month":"04","extern":"1","doi":"10.1103/physrevd.101.083016","author":[{"full_name":"Matilla, José Manuel Zorrilla","last_name":"Matilla","first_name":"José Manuel Zorrilla"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","full_name":"Haiman, Zoltán","last_name":"Haiman","first_name":"Zoltán"}],"date_created":"2024-09-05T12:37:26Z","intvolume":" 101","type":"journal_article","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.1909.04690"}],"publisher":"American Physical Society","_id":"17591"},{"title":"Suppression of H2 cooling in protogalaxies aided by trapped Lyα cooling radiation","date_updated":"2024-09-23T12:42:07Z","publication_identifier":{"issn":["0035-8711","1365-2966"]},"article_processing_charge":"No","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","language":[{"iso":"eng"}],"quality_controlled":"1","status":"public","page":"138-144","citation":{"apa":"Wolcott-Green, J., Haiman, Z., & Bryan, G.

Because H− is a precursor of molecular hydrogen, its destruction can diminish the H2 abundance and cooling. We find that the critical UV flux for suppressing H2-cooling is decreased by ∼15–50 per cent in our fiducial models. Previous one-zone modelling found a larger effect, with Jcrit reduced by a factor of a few; we show that adopting a constant halo mass to determine the trapped Lyα energy density, as is done in the one-zone models, yields a larger reduction in Jcrit, consistent with their findings. Our results nevertheless suggest that Lyα radiation may have an important effect on the thermal evolution of UV-irradiated haloes, and therefore on the potential for massive black hole formation.","lang":"eng"}],"article_type":"original","publication_status":"published","oa_version":"Published Version","day":"09","extern":"1","month":"10"},{"article_number":"138","article_processing_charge":"No","date_updated":"2024-09-23T12:59:52Z","publication_identifier":{"issn":["0004-637X","1538-4357"]},"title":"Cosmic evolution of stellar-mass black hole merger rate in active galactic nuclei","quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","language":[{"iso":"eng"}],"scopus_import":"1","citation":{"ieee":"Y.

We analyze a DNN that has been found in previous work to accurately recover cosmological parameters in simulated maps of the WL convergence (κ). We derive constraints on the cosmological parameter pair (Ωm,σ8) from a combination of three commonly used WL statistics (power spectrum, lensing peaks, and Minkowski functionals), using ray-traced simulated κ maps. We show that the network can improve the inferred parameter constraints relative to this combination by 20% even in the presence of realistic levels of shape noise. We apply a series of well established saliency methods to interpret the DNN and find that the most relevant pixels are those with extreme κ values. For noiseless maps, regions with negative κ account for 86−69% of the attribution of the DNN output, defined as the square of the saliency in input space.

Detecting dual active galactic nuclei (AGN) – active SMBHs at projected separations larger than several parsecs – and binary AGN – probing the scale where SMBHs are bound in a Keplerian binary – is an observational challenge. The study of AGN pairs (either dual or binary) also represents an overarching theoretical problem in cosmology and astrophysics. The AGN triggering calls for detailed knowledge of the hydrodynamical conditions of gas in the imminent surroundings of the SMBHs and, at the same time, their duality calls for detailed knowledge on how galaxies assemble through major and minor mergers and grow fed by matter along the filaments of the cosmic web. This review describes the techniques used across the electromagnetic spectrum to detect dual and binary AGN candidates and proposes new avenues for their search. The current observational status is compared with the state-of-the-art numerical simulations and models for formation of dual and binary AGN. Binary SMBHs are among the loudest sources of gravitational waves (GWs) in the Universe. The search for a background of GWs at nHz frequencies from inspiralling SMBHs at low redshifts, and the direct detection of signals from their coalescence by the Laser Interferometer Space Antenna in the next decade, make this a theme of major interest for multi-messenger astrophysics.

In agreement with some earlier studies, we find that the net torque on the binary is positive for mass ratios close to unity, and that accretion always drives the binary toward equal mass. Accretion variability depends sensitively on the numerical sink prescription, but the torque and relative accretion onto each component do not depend on the sink timescale. Positive torque and highly variable accretion occurs only for mass ratios greater than around 0.05. This means that for mass ratios below 0.05, the binary would migrate inward until the secondary accreted sufficient mass, after which it would execute a U-turn and migrate outward. We explore a range of viscosities, from α = 0.03 to α = 0.15, and find that this outward torque is proportional to the viscous torque, so that torque per unit accreted mass is independent of α. Dependence of accretion and torque on mass ratio is explored in detail, densely sampling mass ratios between 0.01 and unity. For mass ratio q > 0.2, accretion variability is found to exhibit a distinct sawtooth pattern, typically with a five-orbit cycle that provides a smoking gun prediction for variable quasars observed over long periods, as a potential means to confirm the presence of a binary.","lang":"eng"}],"external_id":{"arxiv":["1911.05506"]},"oa_version":"Preprint","day":"17","month":"09","extern":"1","title":"Circumbinary disks: Accretion and torque as a function of mass ratio and disk viscosity","publication_identifier":{"issn":["0004-637X","1538-4357"]},"date_updated":"2024-09-23T13:39:03Z","article_processing_charge":"No","article_number":"25","language":[{"iso":"eng"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","quality_controlled":"1","status":"public","publication":"The Astrophysical Journal","citation":{"ama":"Duffell PC, D’Orazio D, Derdzinski A, et al.

This discrepancy arises from technical limitations, and also from publication bias toward replicating fiducial numerical models. Here we present the first systematic study of how the binary's orbital evolution varies with disk scale height. We report three key results: (1) Binary orbital evolution switches from outspiralling for warm disks (aspect ratio ~0.1), to inspiralling for more realistic cooler, thinner disks at a critical aspect ratio ~0.04, corresponding to orbital Mach number ~25. (2) The net torque on the binary arises from a competition between positive torque from gas orbiting close to the black holes, and negative torque from the inner edge of the CBD, which is denser for thinner disks. This leads to increasingly negative net torques on the binary for increasingly thin disks. (3) The accretion rate is modestly suppressed with increasing Mach number. We discuss how our results may influence modeling of the nano-Hz gravitational wave background, as well as estimates of the LISA merger event rate."}],"publication_status":"published","article_type":"original","arxiv":1,"date_published":"2020-08-28T00:00:00Z","volume":900,"oa":1,"year":"2020","extern":"1","month":"08","oa_version":"Preprint","external_id":{"arxiv":["2005.09555"]},"day":"28"},{"day":"18","oa_version":"Preprint","external_id":{"arxiv":["1911.11142"]},"month":"02","extern":"1","volume":890,"date_published":"2020-02-18T00:00:00Z","oa":1,"year":"2020","arxiv":1,"abstract":[{"lang":"eng","text":"Despite the rapidly growing number of stellar-mass binary black hole mergers discovered through gravitational waves, the origin of these binaries is still not known.

Hierarchical events carry signatures such as higher-than-usual black hole mass and spin. Here we show that the recently reported gravitational-wave candidate, GW170817A, could be the result of such a hierarchical merger.

Here we investigate the impact of the configurational degrees of freedom of a ferrocene derivative on its single-molecule junction conductance. Measurements indicate that the conductance of the ferrocene derivative, which is suppressed by 2 orders of magnitude as compared to a fully conjugated analogue, can be modulated by altering the junction configuration. Ab initio transport calculations show that the low conductance is a consequence of destructive quantum interference effects of the Fano type that arise from the hybridization of localized metal-based d-orbitals and the delocalized ligand-based π-system. By rotation of the Cp rings, the hybridization, and thus the quantum interference, can be mechanically controlled, resulting in a conductance modulation that is seen experimentally.","lang":"eng"}],"_id":"17908","publisher":"American Chemical Society","main_file_link":[{"open_access":"1","url":"https://doi.org/10.26434/chemrxiv.12252059.v1"}],"date_created":"2024-09-09T07:18:19Z","author":[{"first_name":"María","last_name":"Camarasa-Gómez","full_name":"Camarasa-Gómez, María"},{"last_name":"Hernangómez-Pérez","first_name":"Daniel","full_name":"Hernangómez-Pérez, Daniel"},{"first_name":"Michael S.","last_name":"Inkpen","full_name":"Inkpen, Michael S."},{"last_name":"Lovat","first_name":"Giacomo","full_name":"Lovat, Giacomo"},{"last_name":"Fung","first_name":"E-Dean","full_name":"Fung, E-Dean"},{"last_name":"Roy","first_name":"Xavier","full_name":"Roy, Xavier"},{"orcid":"0000-0002-6957-6089","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","last_name":"Venkataraman","first_name":"Latha"},{"full_name":"Evers, Ferdinand","first_name":"Ferdinand","last_name":"Evers"}],"doi":"10.1021/acs.nanolett.0c01956","intvolume":" 20","type":"journal_article"},{"publication":"Nanoscale","citation":{"ista":"Magyarkuti A, Balogh N, Balogh Z, Venkataraman L, Halbritter A. 2020.

Here we exploit the efficient feature recognition properties of neural networks to automatically find the relevant trace classes. To eliminate the need for manually labeled training data we apply a combined method, which automatically selects training traces according to the extreme values of principal component projections or some auxiliary measured quantities. Then the network captures the features of these characteristic traces and generalizes its inference to the entire dataset.

While fractional quantum Hall states could soon be implemented in small atomic ensembles, detecting their signatures in few-particle settings remains a fundamental challenge. In this work, we numerically analyze the center-of-mass Hall drift of a small ensemble of hardcore bosons, initially prepared in the ground state of the Harper-Hofstadter-Hubbard model in a box potential. By monitoring the Hall drift upon release, for a wide range of magnetic flux values, we identify an emergent Hall plateau compatible with a fractional Chern insulator state: The extracted Hall conductivity approaches a fractional value determined by the many-body Chern number, while the width of the plateau agrees with the spectral and topological properties of the prepared ground state. Besides, a direct application of Streda's formula indicates that such Hall plateaus can also be directly obtained from static density-profile measurements. Our calculations suggest that fractional Chern insulators can be detected in cold-atom experiments, using available detection methods."}],"_id":"18194","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1103/PhysRevA.102.063316"}],"publisher":"American Physical Society","author":[{"full_name":"Repellin, C.","last_name":"Repellin","first_name":"C."},{"id":"b75b3f45-7995-11ef-9bfd-9a9cd02c3577","full_name":"Leonard, Julian","last_name":"Leonard","first_name":"Julian"},{"full_name":"Goldman, N.","first_name":"N.","last_name":"Goldman"}],"date_created":"2024-10-07T11:48:07Z","doi":"10.1103/physreva.102.063316","type":"journal_article","intvolume":" 102","issue":"6","ddc":["530"],"status":"public","publication":"Physical Review A","citation":{"chicago":"Repellin, C., Julian Leonard, and N.

One of the major obstacles hindering the ubiquitous use of CNNs for inference on low-power edge devices is their high computational complexity and memory bandwidth requirements. The latter often dominates the energy footprint on modern hardware. In this paper, we introduce a lossy transform coding approach, inspired by image and video compression, designed to reduce the memory bandwidth due to the storage of intermediate activation calculation results. Our method does not require fine-tuning the network weights and halves the data transfer volumes to the main memory by compressing feature maps, which are highly correlated, with variable length coding. Our method outperform previous approach in term of the number of bits per value with minor accuracy degradation on ResNet-34 and MobileNetV2. We analyze the performance of our approach on a variety of CNN architectures and demonstrate that FPGA implementation of ResNet-18 with our approach results in a reduction of around 40% in the memory energy footprint, compared to quantized network, with negligible impact on accuracy. When allowing accuracy degradation of up to 2%, the reduction of 60% is achieved.

The long acquisition times, however, make it more prone to motion artifacts as well as contribute to the relative high costs of this examination. Over the years, multiple studies concentrated on designing reduced measurement schemes and image reconstruction schemes for MRI, however these problems have been so far addressed separately. On the other hand, recent works in optical computational imaging have demonstrated growing success of simultaneous learning-based design of the acquisition and reconstruction schemes manifesting significant improvement in the reconstruction quality with a constrained time budget. Inspired by these successes, in this work, we propose to learn accelerated MR acquisition schemes (in the form of Cartesian trajectories) jointly with the image reconstruction operator. To this end, we propose an algorithm for training the combined acquisition-reconstruction pipeline end-to-end in a differentiable way. We demonstrate the significance of using the learned Cartesian trajectories at different speed up rates.

Such data sets are expensive and time consuming to create and therefore difficult to obtain on a large scale. In this work, we propose to exploit the natural correlation in narrations and the visual presence of objects in video, to learn an object detector and retrieval without any manual labeling involved. We pose the problem as weakly supervised learning with noisy labels, and propose a novel object detection paradigm under these constraints. We handle the background rejection by using contrastive samples and confront the high level of label noise with a new clustering score. Our evaluation is based on a set of 11 manually annotated objects in over 5000 frames. We show comparison to a weakly-supervised approach as baseline and provide a strongly labeled upper bound.","lang":"eng"}],"publication_status":"published","date_published":"2020-03-05T00:00:00Z","oa":1,"year":"2020","arxiv":1},{"article_processing_charge":"No","article_number":"8954088","title":"Laso: Label-set operations networks for multi-label few-shot learning","publication_identifier":{"eissn":["2575-7075"],"isbn":["9781728132945"]},"date_updated":"2024-12-05T15:33:21Z","language":[{"iso":"eng"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","conference":{"start_date":"2019-06-15","end_date":"2019-06-20","location":"Long Beach, CA, United States","name":"32nd IEEE/CVF Conference on Computer Vision and Pattern Recognition"},"quality_controlled":"1","publication":"2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)","citation":{"ieee":"A.

However, current synthesis approaches only address the scenario of a single category label per image. In this work, we propose a novel technique for synthesizing samples with multiple labels for the (yet unhandled) multi-label few-shot classification scenario. We propose to combine pairs of given examples in feature space, so that the resulting synthesized feature vectors will correspond to examples whose label sets are obtained through certain set operations on the label sets of the corresponding input pairs. Thus, our method is capable of producing a sample containing the intersection, union or set-difference of labels present in two input samples. As we show, these set operations generalize to labels unseen during training. This enables performing augmentation on examples of novel categories, thus, facilitating multi-label few-shot classifier learning. We conduct numerous experiments showing promising results for the label-set manipulation capabilities of the proposed approach, both directly (using the classification and retrieval metrics), and in the context of performing data augmentation for multi-label few-shot learning. We propose a benchmark for this new and challenging task and show that our method compares favorably to all the common baselines.","lang":"eng"}],"arxiv":1,"oa":1,"year":"2020","date_published":"2020-01-09T00:00:00Z","extern":"1","month":"01","external_id":{"arxiv":["1902.09811"]},"oa_version":"Preprint","day":"09"},{"OA_type":"green","quality_controlled":"1","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","date_updated":"2026-06-25T08:39:30Z","publication_identifier":{"eissn":["1432-1297"],"issn":["0020-9910"]},"title":"Invariance of white noise for KdV on the line","issue":"1","scopus_import":"1","page":"203-282","citation":{"ieee":"R.
