Reanalysis of Stage-III cosmic shear surveys: A comprehensive study of shear diagnostic tests

Kavli Affiliate: Chihway Chang | First 5 Authors: Jazmine Jefferson, Jazmine Jefferson, , , | Summary: In recent years, shear catalogs have been released by various Stage-III weak lensing surveys including the Kilo-Degree Survey, the Dark Energy Survey, and the Hyper Suprime-Cam Subaru Strategic Program. These shear catalogs have undergone rigorous validation tests to ensure […]

The Relative Contributions of Accretion Disk versus Jet to the Optical and Mid-infrared Variability of Seyfert Galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Vineet Ojha, Vineet Ojha, , , | Summary: We performed a comprehensive analysis of flux and color variability in a redshift-matched sample of Seyfert galaxies, comprising 23 gamma-ray-detected narrow-line Seyfert 1 galaxies (gNLS1s), 190 non-gamma-ray-detected narrow-line Seyfert 1 galaxies (ngNLS1s), and 10 gamma-ray-detected broad-line Seyfert 1 […]

SAPPHIRES: Extremely Metal-Poor Galaxy Candidates with $12+{rm log(O/H)}<7.0$ at $zsim5-7$ from Deep JWST/NIRCam Grism Observations

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tiger Yu-Yang Hsiao, Fengwu Sun, Xiaojing Lin, Dan Coe, Eiichi Egami | Summary: Population III stars, the hypothetical first generation metal-free stars, have yet to be discovered. Even after three years of successful JWST operations, studies have shown that most galaxies identified to date at $z > […]

The eROSITA Final Equatorial Depth Survey (eFEDS): SDSS spectroscopic observations of X-ray sources

Kavli Affiliate: Claudio Ricci | First 5 Authors: Catarina Aydar, Andrea Merloni, Tom Dwelly, Johan Comparat, Mara Salvato | Summary: We present one of the largest uniform optical spectroscopic surveys of X-ray selected sources to date that were observed as a pilot study for the Black Hole Mapper (BHM) survey. The BHM program of the […]

Meta-Learning the Optimal Mixture of Strategies for Online Portfolio Selection

Kavli Affiliate: Jia Liu | First 5 Authors: Jiayu Shen, Jia Liu, Zhiping Chen, , | Summary: This paper presents an innovative online portfolio selection model, situated within a meta-learning framework, that leverages a mixture policies strategy. The core idea is to simulate a fund that employs multiple fund managers, each skilled in handling different […]

The Disks In Scorpius-Centaurus Survey (DISCS) I: Four Newly-Resolved Debris Disks in Polarized Intensity Light

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Justin Hom, Thomas M. Esposito, Katie A. Crotts, Gaspard DuchĂȘne, Jennifer Patience | Summary: The presence of infrared excesses around stars directly correlates to spatially-resolved imaging detections of circumstellar disks at both mm and optical/near-infrared wavelengths. High contrast imagers have resolved dozens of circumstellar disks with scattered […]

Redshift Assessment Infrastructure Layers (RAIL): Rubin-era photometric redshift stress-testing and at-scale production

Kavli Affiliate: Eric Charles | First 5 Authors: The RAIL Team, Jan Luca van den Busch, Eric Charles, Johann Cohen-Tanugi, Alice Crafford | Summary: Virtually all extragalactic use cases of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) require the use of galaxy redshift information, yet the vast majority of its […]

Evidence of a fraction of LIGO/Virgo/KAGRA events coming from active galactic nuclei

Kavli Affiliate: Xian Chen | First 5 Authors: Liang-Gui Zhu, Xian Chen, , , | Summary: The formation channels of the gravitational-wave (GW) sources detected by LIGO/Virgo/KAGRA (LVK) remain poorly constrained. Active galactic nucleus (AGN) has been proposed as one of the potential hosts but the fraction of GW events originating from AGNs has not […]
