Detection of stellar light from quasar host galaxies at redshifts above 6
Xuheng Ding, Masafusa Onoue, John D. Silverman +41
The detection of starlight from the host galaxies of quasars during the reionization epoch () has been elusive, even with deep HST observations. The current highest redshift q…
COSMOS-Web: An Overview of the JWST Cosmic Origins Survey
Caitlin M. Casey, Jeyhan S. Kartaltepe, Nicole E. Drakos +82
We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hour treasury program conducted by the James Webb Space Telescope in its first cycle of observations…
Opening the era of quasar host studies at high redshift with JWST
Xuheng Ding, John D. Silverman, Masafusa Onoue
We measure the host galaxy properties of five quasars with selected from SDSS and AEGIS, which fall within the JWST/HST CEERS survey area. A PSF library is constr…
A machine learning approach to assessing the presence of substructure in quasar host galaxies using the Hyper Suprime-Cam Subaru Strategic Program
Chris Nagele, John D. Silverman, Tilman Hartwig +4
The conditions under which galactic nuclear regions become active are largely unknown, although it has been hypothesized that secular processes related to galaxy morphology could p…
A Candidate of a Least-Massive Black Hole at the First 1.1 Billion Years of the Universe
Masafusa Onoue, Kohei Inayoshi, Xuheng Ding +6
We report a candidate of a low-luminosity active galactic nucleus (AGN) at z=5 that was selected from the first near-infrared images of the JWST CEERS project. This source, named C…
Impact of gravitational lensing on black hole mass function inference with third-generation gravitational wave detectors
Xianlong He, Kai Liao, Xuheng Ding +4
The recent rapid growth of the black hole (BH) catalog from gravitational waves (GWs), has allowed us to study the substructure of black hole mass function (BHMF) beyond the simple…
Concordance between observations and simulations in the evolution of the mass relation between supermassive black holes and their host galaxies
Xuheng Ding, John D. Silverman, Tommaso Treu +7
We carry out a comparative analysis of the relation between the mass of supermassive black holes (BHs) and the stellar mass of their host galaxies at using well-matched…
Inferences on relations between distant supermassive black holes and their hosts complemented by the galaxy fundamental plane
John Silverman, Junyao Li, Xuheng Ding
The realization of fundamental relations between supermassive black holes and their host galaxies would have profound implications in astrophysics. To add further context to studie…
