Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski, Hollis B. Akins, Fergus Cullen | Summary: We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a $z=9.288$ broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam photometry, follow-up NIRSpec/PRISM spectroscopy […]

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: 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 […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Marzena Śniegowska, Benny Trakhtenbrot, Lydia Makrygianni, Iair Arcavi, Claudio Ricci | Summary: AT 2019aalc is a peculiar sequence of highly variable emission events observed towards the nucleus of the broad-line AGN SDSS J152416.66+045119.0. The system exhibited two distinct UV/optical flares (the first detected in 2019, the second […]
Kavli Affiliate: Xuebing Wu | First 5 Authors: Jingbo Sun, Jingbo Sun, , , | Summary: The search for robust evidence of intermediate-mass black holes (IMBHs) is crucial for understanding black hole seeding process and the formation of supermassive black holes in the early Universe. NGC 4395 and POX 52 are two prototypical IMBH hosts, […]
