Little Red Dots: Rapidly Growing Black Holes Reddened by Extended Dusty Flows

Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhengrong Li, Kohei Inayoshi, Kejian Chen, Kohei Ichikawa, Luis C. Ho | Summary: The James Webb Space Telescope (JWST) observations have revolutionized extragalactic research, particularly with the discovery of little red dots (LRD), which we propose are dust-reddened broad-line active galactic nuclei (AGNs). Their unique v-shape […]

The white-light superflares from cool stars in GWAC triggers

Kavli Affiliate: Jing Wang | First 5 Authors: Guang-Wei Li, Liang Wang, Hai-Long Yuan, Li-Ping Xin, Jing Wang | Summary: M-type stars are the ones that flare most frequently, but how big their maximum flare energy can reach is still unknown. We present 163 flares from 162 individual M2 through L1-type stars that triggered the […]

Spectroastrometry and Reverberation Mapping (SARM) of Active Galactic Nuclei. I. The H$β$ Broad-line Region Structure and Black Hole Mass of Five Quasars

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yan-Rong Li, Chen Hu, Zhu-Heng Yao, Yong-Jie Chen, Hua-Rui Bai | Summary: We conduct a reverberation mapping (RM) campaign to spectroscopically monitor a sample of selected bright active galactic nuclei with large anticipated broad-line region (BLR) sizes adequate for spectroastrometric observations by the GRAVITY instrument on […]

Circumnuclear Dust in Luminous Early-Type Galaxies — I. Sample Properties and Stellar Luminosity Models

Kavli Affiliate: Luis C. Ho | First 5 Authors: Jared R. Davidson, Benjamin D. Boizelle, Jonelle L. Walsh, Aaron J. Barth, Emma Rasmussen | Summary: Dusty circumnuclear disks (CNDs) in luminous early-type galaxies (ETGs) show regular, dynamically cold molecular gas kinematics. For a growing number of ETGs, Atacama Large Millimeter/sub-millimeter Array (ALMA) CO imaging and […]

Investigating the interplay between AGN coronal properties and hard X-ray variability with NuSTAR

Kavli Affiliate: Claudio Ricci | First 5 Authors: Roberto Serafinelli, Alessandra De Rosa, Alessia Tortosa, Luigi Stella, Fausto Vagnetti | Summary: Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short time scales. However, the driver of the X-ray variability is still poorly understood. Previous results suggest that the hot […]

TVR-Ranking: A Dataset for Ranked Video Moment Retrieval with Imprecise Queries

Kavli Affiliate: Jing Wang | First 5 Authors: Renjie Liang, Li Li, Chongzhi Zhang, Jing Wang, Xizhou Zhu | Summary: In this paper, we propose the task of textit{Ranked Video Moment Retrieval} (RVMR) to locate a ranked list of matching moments from a collection of videos, through queries in natural language. Although a few related […]
