Abelian envelopes of exact categories and highest weight categories

Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define admissible and weakly admissible subcategories in exact categories and prove that the former induce semi-orthogonal decompositions on the derived categories. We develop the theory of thin exact categories, an exact-category analogue of triangulated categories generated by exceptional […]

Revealing Ionization Conditions of Sz 102 with Spatially Resolved [Ne III] Microjets

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Chun-Fan Liu, Hsien Shang, Gregory J. Herczeg, Frederick M. Walter, | Summary: Forbidden neon emission lines from small-scale microjets can probe high-energy processes in low-mass young stellar systems. We obtained spatially resolved [Ne III] spectra of the microjets from the classical T Tauri Star Sz 102 […]

The Atacama Cosmology Telescope: Detection of mm-wave transient sources

Kavli Affiliate: David Spergel | First 5 Authors: Sigurd Naess, Nick Battaglia, J. Richard Bond, Erminia Calabrese, Steve K. Choi | Summary: We report on the serendipitous discovery of three transient mm-wave sources using data from the Atacama Cosmology Telescope. The first, detected at RA = 273.8138, dec = -49.4628 at ${sim}50sigma$ total, brightened from […]

FLTrust: Byzantine-robust Federated Learning via Trust Bootstrapping

Kavli Affiliate: Jia Liu | First 5 Authors: Xiaoyu Cao, Minghong Fang, Jia Liu, Neil Zhenqiang Gong, | Summary: Byzantine-robust federated learning aims to enable a service provider to learn an accurate global model when a bounded number of clients are malicious. The key idea of existing Byzantine-robust federated learning methods is that the service […]

The R-Process Alliance: Chemo-Dynamically Tagged Groups of Halo $r$-Process-Enhanced Stars Reveal a Shared Chemical-Evolution History

Kavli Affiliate: Anna Frebel | First 5 Authors: Dmitrii Gudin, Derek Shank, Timothy C. Beers, Zhen Yuan, Guilherme Limberg | Summary: We derive dynamical parameters for a large sample of 446 $r$-process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the $R$-Process Alliance, supplemented by […]

Observables for Recoil Identification in High-Definition Gas Time Projection Chambers

Kavli Affiliate: Cosmin Deaconu | First 5 Authors: Majd Ghrear, Sven E. Vahsen, Cosmin Deaconu, , | Summary: Directional detection of nuclear recoils is broadly desirable in nuclear and particle physics. At low recoil energies, this capability may be used to confirm the cosmological origin of a dark matter signal, to penetrate the so-called neutrino […]

RR Lyrae variables in Messier 53: Near-infrared Period–Luminosity relations and the calibration using Gaia Early Data Release 3

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs, Soung-Chul Yang, Gregory J. Herczeg | Summary: We present new near-infrared, $JHK_s$, Period–Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch $JHK_s$ observations, obtained with the WIRCam instrument on the […]
