Kavli Affiliate: Jinyi Shangguan | Summary:Little red dots (LRDs) are a newly identified class of broad-line active galactic nuclei (AGN) with a distinctive v-shape spectrum characterized by red optical and blue UV continuum emission. Their high abundance at redshifts of $zsim6-8$ and decline at lower redshifts suggest a transient origin. We propose that the spectral […]

Kavli Affiliate: Xian Chen | First 5 Authors: Jie Cao, Chloe Qianhui Zhao, Xian Chen, Shuman Wang, Christian Schunn | Summary: Producing large volumes of high-quality, timely feedback poses significant challenges to instructors. To address this issue, automation technologies-particularly Large Language Models (LLMs)-show great potential. However, current LLM-based research still shows room for improvement in […]
Kavli Affiliate: Hu Zhan | First 5 Authors: Hang Zhou, Xin Wang, Matthew A. Malkan, Tommaso Treu, Yiming Yang | Summary: The MAMMOTH-MOSFIRE program is a deep Keck MOSFIRE K-band spectroscopic follow-up of emission-line galaxies identified in the MAMMOTH-Grism HST WFC3/G141 slitless spectroscopic survey, targeting the core regions of three most massive galaxy protoclusters at […]
Kavli Affiliate: Hu Zhan | First 5 Authors: Hang Zhou, Hang Zhou, , , | Summary: The MAMMOTH-MOSFIRE program is a deep Keck/MOSFIRE K-band spectroscopic follow-up of emission-line galaxies identified in the MAMMOTH-Grism HST/WFC3 G141 slitless spectroscopic survey, targeting the core regions of three most massive galaxy protoclusters at cosmic noon. To introduce this program, […]
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 […]
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 […]
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 […]
