Bluefors and Zurich Instruments have supported the growth of this field from the 2010s onwards by providing well-engineered and reliable measurement infrastructure [2]– [6]. Having a long and stable qubit lifetime is a critical system property. Therefore, considerable effort has already gone into measuring qubit energy-relaxation timescales and their fluctuations, see Refs. [7]–[10] among others. Accurately extracting the statistics of a quantum device requires users to perform time consuming measurements. One measurement challenge is that the detection of the state-dependent\r\nresponse of a superconducting resonator due to a dispersively-coupled qubit requires an inherently low signal level. Consequently, measurements must be performed using a microwave probe that contains only a few microwave photons. Improving the signal-to-noise ratio (SNR) by using near-quantum limited parametric amplifiers as well as the use of optimized signal processing enabled by efficient room temperature instrumentation help to reduce measurement time. An empirical observation for fixed frequency transmons from recent literature is that as the energy-relaxation time 𝑇𝑇1 increases, so do its natural temporal fluctuations [7], [10]. This necessitates many repeated measurements to understand the statistics (see for example, Ref. [10]). In addition, as state-of-the-art qubits increase in lifetime, longer\r\nmeasurement times are expected to obtain accurate statistics. As described below, the scaling of the widths of the qubit energy-relaxation distributions also reveal clues about the origin of the energy-relaxation.","lang":"eng"}],"citation":{"ieee":"S.

Transduction of microglia is mostly excluded from this strategy, likely due to the cells’ heterogeneous state upon environmental changes, which makes AAV design challenging. Here, we established the retina as a model system for microglial AAV validation and optimization. First, we show that AAV2/6 transduced microglia in both synaptic layers, where layer preference corresponds to the intravitreal or subretinal delivery method. Surprisingly, we observed significantly enhanced microglial transduction during photoreceptor degeneration. Thus, we modified the AAV6 capsid to reduce heparin binding by introducing four point mutations (K531E, R576Q, K493S, and K459S), resulting in increased microglial transduction in the outer plexiform layer. Finally, to improve microglial-specific transduction, we validated a Cre-dependent transgene delivery cassette for use in combination with the Cx3cr1CreERT2 mouse line. Together, our results provide a foundation for future studies optimizing AAV-mediated microglia transduction and highlight that environmental conditions influence microglial transduction efficiency.\r\n"}],"publisher":"Elsevier","project":[{"name":"Microglia action towards neuronal circuit formation and function in health and disease","grant_number":"715571","_id":"25D4A630-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"oa":1,"month":"12","page":"210-224","year":"2021","language":[{"iso":"eng"}],"isi":1,"tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"ec_funded":1,"date_updated":"2025-04-14T07:41:46Z","title":"Optimizing AAV2/6 microglial targeting identified enhanced efficiency in the photoreceptor degenerative environment","date_published":"2021-12-10T00:00:00Z","author":[{"full_name":"Maes, Margaret E","last_name":"Maes","orcid":"0000-0001-9642-1085","first_name":"Margaret E","id":"3838F452-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Gabriele M.","last_name":"Wögenstein","full_name":"Wögenstein, Gabriele M."},{"full_name":"Colombo, Gloria","last_name":"Colombo","orcid":"0000-0001-9434-8902","id":"3483CF6C-F248-11E8-B48F-1D18A9856A87","first_name":"Gloria"},{"orcid":"0000-0001-8293-4568","last_name":"Casado Polanco","id":"15240fc1-dbcd-11ea-9d1d-ac5a786425fd","first_name":"Raquel","full_name":"Casado Polanco, Raquel"},{"last_name":"Siegert","orcid":"0000-0001-8635-0877","id":"36ACD32E-F248-11E8-B48F-1D18A9856A87","first_name":"Sandra","full_name":"Siegert, Sandra"}],"department":[{"_id":"SaSi"},{"_id":"SiHi"}],"article_processing_charge":"Yes","external_id":{"isi":["000748748500019"]}},{"corr_author":"1","date_created":"2022-01-26T08:01:30Z","alternative_title":["Conference Series"],"type":"conference","conference":{"location":"Virtual","start_date":"2021-10-20","name":"FMCAD: Formal Methods in Computer-Aided Design","end_date":"2021-10-22"},"publication":"Proceedings of the 21st Conference on Formal Methods in Computer-Aided Design","status":"public","oa_version":"Published Version","_id":"10688","publication_identifier":{"isbn":["978-3-85448-046-4"]},"publication_status":"published","intvolume":" 2","day":"01","acknowledgement":"This research was performed while Bernhard Kragl was at IST Austria, supported in part by the Austrian Science Fund (FWF) under grant Z211-N23 (Wittgenstein Award).","has_accepted_license":"1","editor":[{"full_name":"Ruzica, Piskac","last_name":"Ruzica","first_name":"Piskac"},{"full_name":"Whalen, Michael W.","last_name":"Whalen","first_name":"Michael W."}],"ddc":["000"],"scopus_import":"1","doi":"10.34727/2021/isbn.978-3-85448-046-4_23","citation":{"mla":"Kragl, Bernhard, and Shaz Qadeer. “The Civl Verifier.” Proceedings of the 21st Conference on Formal Methods in Computer-Aided Design, edited by Piskac Ruzica and Michael W.

Rubin Observatory is expected to discover tens of millions of quasars. A significant fraction of these could be powered by coalescing massive black hole (MBH) binaries, since many quasars are believed to be triggered by mergers. We show that under plausible assumptions about the luminosity functions, lifetimes, and binary fractions of quasars, we expect the full LSST quasar catalogue to contain between 20 and 100 million compact MBH binaries with masses M = 105–9M⊙, redshifts z = 0–6, and orbital periods P = 1–70 d. Their light-curves are expected to be distinctly periodic, which can be confidently distinguished from stochastic red-noise variability, because LSST will cover dozens, or even hundreds of cycles. A very small subset of 10–150 ultracompact (P ≲ 1 d) binary quasars among these will, over ∼5–15 yr, evolve into the mHz gravitational-wave frequency band and can be detected by LISA. They can therefore be regarded as ‘LISA verification binaries’, analogous to short-period Galactic compact-object binaries.

This paper reports the results of a study by the LISA Science Group, which was charged with assessing the additional science return of increasing the mission lifetime. We explore various observational scenarios to assess the impact of mission duration on the main science objectives of the mission. We find that the science investigations most affected by mission duration concern the search for seed black holes at cosmic dawn, as well as the study of stellar-origin black holes and of their formation channels via multi-band and multi-messenger observations.

Several scenarios have been proposed to date to explain massive BH formation, from the low-mass seed BH remnants of the first generation of stars to the massive seed BHs resulting from the rapid collapse of massive gas clouds. However, the plausibility of some of these scenarios to occur within the progenitors of high-z quasars has not yet been thoroughly explored. In this work, we investigate, by combining dark-matter only N-body simulations with a semi-analytic framework, whether the conditions for the formation of massive seed BHs from synchronised atomic-cooling halo pairs and/or dynamically-heated mini-haloes are fulfilled in the overdense regions where the progenitors of a typical high-redshift quasar host form and evolve. Our analysis shows that the peculiar conditions in such regions, i.e. strong halo clustering and high star formation rates, are crucial to produce a non-negligible number of massive seed BH host candidates: we find ≈1400 dynamically heated metal-free mini-haloes, including one of these which evolves to a synchronised pair and ends up in the massive quasar-host halo by z=6. This demonstrates that the progenitors of high-redshift quasar host haloes can harbour early massive seed BHs. Our results further suggest that multiple massive seed BHs may form in or near the quasar host's progenitors, potentially merging at lower redshifts and yielding gravitational wave events."}],"_id":"17610","publication_identifier":{"issn":["0035-8711","1365-2966"]},"publication_status":"published","day":"24","extern":"1","intvolume":" 503","scopus_import":"1","arxiv":1,"date_created":"2024-09-05T13:22:23Z","type":"journal_article","status":"public","publication":"Monthly Notices of the Royal Astronomical Society","oa_version":"Preprint","quality_controlled":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","doi":"10.1093/mnras/stab692","article_type":"original","citation":{"mla":"Lupi, Alessandro, et al. “Forming Massive Seed Black Holes in High-Redshift Quasar Host Progenitors.” Monthly Notices of the Royal Astronomical Society, vol. 503, no. 4, Oxford University Press, 2021, pp. 5046–60, doi:10.1093/mnras/stab692.","ama":"Lupi A, Haiman Z, Volonteri M.

In particular, ultracold atoms in optical lattices provide a highly controllable and adaptable platform to study such new types of quantum matter. However, finding a clear route to realize non-Abelian quantum Hall states in these systems remains challenging. Here we use the density-matrix renormalization-group (DMRG) method to study the Hofstadter-Bose-Hubbard model at filling factor 𝜈=1 and find strong indications that at 𝛼=1/6 magnetic flux quanta per plaquette the ground state is a lattice analog of the continuum non-Abelian Pfaffian. We study the on-site correlations of the ground state, which indicate its paired nature at 𝜈=1, and find an incompressible state characterized by a charge gap in the bulk. We argue that the emergence of a charge density wave on thin cylinders and the behavior of the two- and three-particle correlation functions at short distances provide evidence for the state being closely related to the continuum Pfaffian. The signatures discussed in this letter are accessible in current cold atom experiments and we show that the Pfaffian-like state is readily realizable in few-body systems using adiabatic preparation schemes."}],"publisher":"American Physical Society","month":"04","year":"2021","language":[{"iso":"eng"}],"oa":1,"article_processing_charge":"No","external_id":{"arxiv":["2011.02477"]},"issue":"16","title":"Bosonic Pfaffian state in the Hofstadter-Bose-Hubbard model","date_updated":"2024-10-08T09:55:46Z","date_published":"2021-04-15T00:00:00Z","author":[{"first_name":"F.

The idea behind expansion microscopy is to embed the biological sample in a swellable gel, and then to expand it isotropically, thereby increasing the distance between the fluorophores. This approach breaks the diffraction barrier by simply separating the emission point-spread-functions of the fluorophores. The resolution attainable in expansion microscopy is thus directly dependent on the separation that can be achieved, i.e. on the expansion factor. The original implementation of the technique achieved an expansion factor of fourfold, for a resolution of 70–80 nm. The subsequently developed X10 method achieves an expansion factor of 10-fold, for a resolution of 25–30 nm. This technique can be implemented with minimal technical requirements on any standard fluorescence microscope, and is more easily applied for multi-color imaging than either deterministic or stochastic super-resolution approaches. This renders X10 expansion microscopy a highly promising tool for new biological discoveries, as discussed here, and as demonstrated by several recent applications."}],"publisher":"Elsevier","year":"2021","month":"01","page":"33-56","language":[{"iso":"eng"}],"department":[{"_id":"JoDa"}],"article_processing_charge":"No","external_id":{"pmid":["33478696"]},"title":"Simple multi-color super-resolution by X10 microscopy","date_updated":"2024-10-09T20:59:36Z","date_published":"2021-01-01T00:00:00Z","author":[{"full_name":"Truckenbrodt, Sven M","id":"45812BD4-F248-11E8-B48F-1D18A9856A87","first_name":"Sven M","last_name":"Truckenbrodt"},{"full_name":"Rizzoli, Silvio O.","first_name":"Silvio O.","last_name":"Rizzoli"}]},{"file_date_updated":"2021-02-04T10:34:22Z","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"date_updated":"2021-02-04T10:34:22Z","file_size":683634,"checksum":"7985d7dff94c086e35b94a911d78d9ad","relation":"main_file","content_type":"application/pdf","file_id":"9088","access_level":"open_access","success":1,"date_created":"2021-02-04T10:34:22Z","file_name":"2021_NatureNeuroScience_Bozelos.pdf","creator":"dernst"}],"doi":"10.1038/s41583-020-00408-6","volume":22,"citation":{"ieee":"P.

However, during the discovery of cost-efficient routes for the transaction, critical information may be revealed about the transacting entities. This paper initiates the study of privacy-preserving route discovery mechanisms for payment channel networks. In particular, we present LightPIR, an approach which allows a client to learn the shortest (or cheapest in terms of fees) path between two nodes without revealing any information about the endpoints of the transaction to the servers. The two main observations which allow for an efficient solution in LightPIR are that: (1) surprisingly, hub labelling algorithms – which were developed to preprocess “street network like” graphs so one can later efficiently compute shortest paths – also perform well for the graphs underlying payment channel networks, and that (2) hub labelling algorithms can be conveniently combined with private information retrieval. LightPIR relies on a simple hub labeling heuristic on top of existing hub labeling algorithms which leverages the specific topological features of cryptocurrency networks to further minimize storage and bandwidth overheads. In a case study considering the Lightning network, we show that our approach is an order of magnitude more efficient compared to a privacy-preserving baseline based on using private information retrieval on a database that stores all pairs shortest paths.","lang":"eng"}],"external_id":{"isi":["000853016800008"],"arxiv":["2104.04293"]},"article_processing_charge":"No","department":[{"_id":"KrPi"}],"author":[{"id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","first_name":"Krzysztof Z","last_name":"Pietrzak","orcid":"0000-0002-9139-1654","full_name":"Pietrzak, Krzysztof Z"},{"last_name":"Salem","first_name":"Iosif","full_name":"Salem, Iosif"},{"first_name":"Stefan","last_name":"Schmid","full_name":"Schmid, Stefan"},{"first_name":"Michelle X","id":"2D82B818-F248-11E8-B48F-1D18A9856A87","last_name":"Yeo","orcid":"0009-0001-3676-4809","full_name":"Yeo, Michelle X"}],"main_file_link":[{"url":"https://arxiv.org/abs/2104.04293","open_access":"1"}],"date_published":"2021-06-21T00:00:00Z","title":"LightPIR: Privacy-preserving route discovery for payment channel networks","date_updated":"2026-04-07T13:29:44Z","ec_funded":1,"quality_controlled":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","doi":"10.23919/IFIPNetworking52078.2021.9472205","citation":{"ieee":"K.

The Lyα emitter (LAE) fraction, XLAE, is a potentially powerful probe of the evolution of the intergalactic neutral hydrogen gas fraction. However, uncertainties in the measurement of XLAE are still under debate.\r\nAims. Thanks to deep data obtained with the integral field spectrograph Multi Unit Spectroscopic Explorer (MUSE), we can measure the evolution of the LAE fraction homogeneously over a wide redshift range of z ≈ 3–6 for UV-faint galaxies (down to UV magnitudes of M1500 ≈ −17.75). This is a significantly fainter range than in former studies (M1500 ≤ −18.75) and it allows us to probe the bulk of the population of high-redshift star-forming galaxies.\r\nMethods. We constructed a UV-complete photometric-redshift sample following UV luminosity functions and measured the Lyα emission with MUSE using the latest (second) data release from the MUSE Hubble Ultra Deep Field Survey.\r\nResults. We derived the redshift evolution of XLAE for M1500 ∈ [ − 21.75; −17.75] for the first time with a equivalent width range EW(Lyα) ≥ 65 Å and found low values of XLAE ≲ 30% at z ≲ 6. The best-fit linear relation is XLAE = 0.07+0.06−0.03z − 0.22+0.12−0.24. For M1500 ∈ [ − 20.25; −18.75] and EW(Lyα) ≥ 25 Å, our XLAE values are consistent with those in the literature within 1σ at z ≲ 5, but our median values are systematically lower than reported values over the whole redshift range. In addition, we do not find a significant dependence of XLAE on M1500 for EW(Lyα) ≥ 50 Å at z ≈ 3–4, in contrast with previous work. The differences in XLAE mainly arise from selection biases for Lyman Break Galaxies (LBGs) in the literature: UV-faint LBGs are more easily selected if they have strong Lyα emission, hence XLAE is biased towards higher values when those samples are used.\r\nConclusions. Our results suggest either a lower increase of XLAE towards z ≈ 6 than previously suggested, or even a turnover of XLAE at z ≈ 5.5, which may be the signature of a late or patchy reionization process. We compared our results with predictions from a cosmological galaxy evolution model. We find that a model with a bursty star formation (SF) can reproduce our observed LAE fractions much better than models where SF is a smooth function of time.","lang":"eng"}],"publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"_id":"11503","intvolume":" 638","day":"03","extern":"1","publication_status":"published","acknowledgement":"We thank the anonymous referee for constructive comments and suggestions.

Lyman α (Ly α) emitters (LAEs) at z ∼ 2–6. We find typical stellar masses of 109.3 ± 0.6 M⊙ and star formation rates (SFR) of SFRSED=4.4+10.5−2.4 M⊙ yr−1 and SFRLyα=5.9+6.3−2.6 M⊙ yr−1, combined with very blue UV slopes of β=−2.1+0.5−0.4, but with significant variations within the population. MUV and β are correlated in a similar way to UV-selected sources, but LAEs are consistently bluer. This suggests that LAEs are the youngest and/or most dust-poor subset of the UV-selected population. We also study the Ly α rest-frame equivalent width (EW0) and find 45 ‘extreme’ LAEs with EW0 > 240 Å (3σ), implying a low number density of (7 ± 1) × 10−7 Mpc−3. Overall, we measure little to no evolution of the Ly α EW0 and scale length parameter (w0), which are consistently high (EW0=140+280−70 Å, w0=129+11−11 Å) from z ∼ 6 to z ∼ 2 and below. However, w0 is anticorrelated with MUV and stellar mass. Our results imply that sources selected as LAEs have a high Ly α escape fraction (fesc,Ly α) irrespective of cosmic time, but fesc,Ly α is still higher for UV-fainter and lower mass LAEs. The least massive LAEs (<109.5 M⊙) are typically located above the star formation ‘main sequence’ (MS), but the offset from the MS decreases towards z ∼ 6 and towards 1010 M⊙. Our results imply a lack of evolution in the properties of LAEs across time and reveals the increasing overlap in properties of LAEs and UV-continuum selected galaxies as typical star-forming galaxies at high redshift effectively become LAEs.","lang":"eng"}],"publisher":"Oxford University Press"},{"article_processing_charge":"No","external_id":{"arxiv":["1909.11672"]},"title":"The X-ray and radio activity of typical and luminous Ly α emitters from z ∼ 2 to z ∼ 6: Evidence for a diverse, evolving population","keyword":["Space and Planetary Science","Astronomy and Astrophysics","galaxies: active","galaxies: evolution","galaxies: high-redshift","quasars: supermassive black holes","galaxies: star formation","cosmology: observations","X-rays: galaxies"],"issue":"3","date_updated":"2022-08-18T11:25:31Z","date_published":"2020-04-01T00:00:00Z","main_file_link":[{"url":"https://arxiv.org/abs/1909.11672","open_access":"1"}],"author":[{"full_name":"Calhau, João","first_name":"João","last_name":"Calhau"},{"first_name":"David","last_name":"Sobral","full_name":"Sobral, David"},{"first_name":"Sérgio","last_name":"Santos","full_name":"Santos, Sérgio"},{"orcid":"0000-0003-2871-127X","last_name":"Matthee","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","full_name":"Matthee, Jorryt J"},{"last_name":"Paulino-Afonso","first_name":"Ana","full_name":"Paulino-Afonso, Ana"},{"full_name":"Stroe, Andra","first_name":"Andra","last_name":"Stroe"},{"last_name":"Simmons","first_name":"Brooke","full_name":"Simmons, Brooke"},{"full_name":"Barlow-Hall, Cassandra","last_name":"Barlow-Hall","first_name":"Cassandra"},{"full_name":"Adams, Benjamin","first_name":"Benjamin","last_name":"Adams"}],"abstract":[{"text":"Despite recent progress in understanding Ly α emitters (LAEs), relatively little is known regarding their typical black hole activity across cosmic time. Here, we study the X-ray and radio properties of ∼4000 LAEs at 2.2 < z < 6 from the SC4K survey in the COSMOS field. We detect 254 (6.8per cent±0.4per cent) LAEs individually in the X-rays (S/N > 3) with an average luminosity of 1044.31±0.01ergs−1 and average black hole accretion rate (BHAR) of 0.72±0.01 M⊙ yr−1, consistent with moderate to high accreting active galactic neuclei (AGNs). We detect 120 sources in deep radio data (radio AGN fraction of 3.2per cent±0.3per cent). The global AGN fraction (8.6per cent±0.4per cent) rises with Ly α luminosity and declines with increasing redshift. For X-ray-detected LAEs, Ly α luminosities correlate with the BHARs, suggesting that Ly α luminosity becomes a BHAR indicator. Most LAEs (93.1per cent±0.6per cent) at 2 < z < 6 have no detectable X-ray emission (BHARs < 0.017 M⊙ yr−1). The median star formation rate (SFR) of star-forming LAEs from Ly α and radio luminosities is 7.6+6.6−2.8 M⊙ yr−1. The black hole to galaxy growth ratio (BHAR/SFR) for LAEs is <0.0022, consistent with typical star-forming galaxies and the local BHAR/SFR relation.

Asteroseismology is the most precise method of providing such information for field star populations en masse, but existing samples for the most part have been limited to a few narrow fields of view by the CoRoT and Kepler missions. In an effort to provide well-characterized stellar parameters across a wide range in Galactic position, we present the second data release of red giant asteroseismic parameters for the K2 Galactic Archaeology Program (GAP). We provide ${\\nu }_{\\max }$ and ${\\rm{\\Delta }}\\nu $ based on six independent pipeline analyses; first-ascent red giant branch (RGB) and red clump (RC) evolutionary state classifications from machine learning; and ready-to-use radius and mass coefficients, κR and κM, which, when appropriately multiplied by a solar-scaled effective temperature factor, yield physical stellar radii and masses. In total, we report 4395 radius and mass coefficients, with typical uncertainties of 3.3% (stat.) ± 1% (syst.) for κR and 7.7% (stat.) ± 2% (syst.) for κM among RGB stars, and 5.0% (stat.) ± 1% (syst.) for κR and 10.5% (stat.) ± 2% (syst.) for κM among RC stars. We verify that the sample is nearly complete—except for a dearth of stars with ${\\nu }_{\\max }\\lesssim 10\\mbox{--}20\\,\\mu \\mathrm{Hz}$—by comparing to Galactic models and visual inspection. Our asteroseismic radii agree with radii derived from Gaia Data Release 2 parallaxes to within 2.2% ± 0.3% for RGB stars and 2.0% ± 0.6% for RC stars."}],"article_processing_charge":"No","external_id":{"arxiv":["2012.04051"]},"date_published":"2020-12-01T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2012.04051"}],"author":[{"first_name":"Joel C.","last_name":"Zinn","full_name":"Zinn, Joel C."},{"first_name":"Dennis","last_name":"Stello","full_name":"Stello, Dennis"},{"full_name":"Elsworth, Yvonne","last_name":"Elsworth","first_name":"Yvonne"},{"full_name":"García, Rafael A.","first_name":"Rafael A.","last_name":"García"},{"last_name":"Kallinger","first_name":"Thomas","full_name":"Kallinger, Thomas"},{"last_name":"Mathur","first_name":"Savita","full_name":"Mathur, Savita"},{"full_name":"Mosser, Benoît","last_name":"Mosser","first_name":"Benoît"},{"full_name":"Bugnet, Lisa Annabelle","first_name":"Lisa Annabelle","id":"d9edb345-f866-11ec-9b37-d119b5234501","last_name":"Bugnet","orcid":"0000-0003-0142-4000"},{"full_name":"Jones, Caitlin","last_name":"Jones","first_name":"Caitlin"},{"full_name":"Hon, Marc","first_name":"Marc","last_name":"Hon"},{"full_name":"Sharma, Sanjib","first_name":"Sanjib","last_name":"Sharma"},{"last_name":"Schönrich","first_name":"Ralph","full_name":"Schönrich, Ralph"},{"first_name":"Jack T.","last_name":"Warfield","full_name":"Warfield, Jack T."},{"full_name":"Luger, Rodrigo","first_name":"Rodrigo","last_name":"Luger"},{"full_name":"Pinsonneault, Marc H.","last_name":"Pinsonneault","first_name":"Marc H."},{"full_name":"Johnson, Jennifer A.","last_name":"Johnson","first_name":"Jennifer A."},{"full_name":"Huber, Daniel","first_name":"Daniel","last_name":"Huber"},{"full_name":"Aguirre, Victor Silva","first_name":"Victor Silva","last_name":"Aguirre"},{"first_name":"William J.","last_name":"Chaplin","full_name":"Chaplin, William J."},{"first_name":"Guy R.","last_name":"Davies","full_name":"Davies, Guy R."},{"full_name":"Miglio, Andrea","first_name":"Andrea","last_name":"Miglio"}],"keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"issue":"2","date_updated":"2022-08-22T07:04:45Z","title":"The K2 galactic archaeology program data release 2: Asteroseismic results from campaigns 4, 6, and 7","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.3847/1538-4365/abbee3","article_type":"original","article_number":"23","citation":{"apa":"Zinn, J.
