HST Confirms Sub-5 kpc Dual Quasar Pairs at Cosmic Noon
Qian Wang, Xuheng Ding, John Silverman +12
During cosmic noon (), when both star formation and black hole growth peaked, galaxy mergers are predicted to trigger dual active galactic nuclei (AGN) that eventually co…
SHELLQs-JWST: Revealing the Spectra of Extended Emission in 12 z > 6 Quasar Host Galaxies using the JWST NIRSpec Fixed Slit
Camryn L. Phillips, Michael A. Strauss, Masafusa Onoue +15
We present an analysis of the rest frame optical JWST NIRSpec Fixed Slit spectra of extended host galaxy emission in 12 quasars from the Subaru High-z Exploration of Low-Luminosity…
Extended Components of Little Red Dots in the Rest-Frame Optical
Yiyang Zhang, Xuheng Ding, Lilan Yang +26
Recent JWST observations have revealed a population of red, compact, high-redshift objects called Little Red Dots (LRDs), whose host components have remained largely unconstrained,…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XXIV. 54 New Quasars and Candidate Obscured Quasars at
Yoshiki Matsuoka, Kazushi Iwasawa, Masafusa Onoue +18
We present spectroscopic identification of 43 quasars and 11 candidate obscured quasars in the epoch of reionization (EoR) at , along with 29 galaxies at simil…
SHELLQs-JWST perspective on the intrinsic mass relation between supermassive black holes and their host galaxies at z > 6
John Silverman, Junyao Li, Xuheng Ding +36
The relation between the masses of supermassive black holes (SMBHs) and their host galaxies encodes information on their mode of growth, especially at the earliest epochs. The Jame…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) XXII. Chandra observations of narrow-line quasar candidates at z>6
K. Iwasawa, R. Gilli, F. Vito +13
We report on Chandra X-ray observations of four narrow-line quasar candidates at z~6, selected from the SHELLQs project, based on the Subaru Hyper Suprime-Cam survey. These objects…
SHELLQs. Bridging the Gap: JWST Unveils Obscured Quasars in the Most Luminous Galaxies at z > 6
Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +17
The unprecedented sensitivity of the James Webb Space Telescope (JWST) has uncovered a surprisingly abundant population of mildly obscured, low-luminosity active galactic nuclei (A…
SHELLQs-JWST Unveils the Host Galaxies of 12 Quasars at z>6
Xuheng Ding, Masafusa Onoue, John D. Silverman +35
The advent of JWST has opened new horizons in the study of quasar host galaxies during the reionization epoch (z>6). Building upon our previous initial measurements of stellar ligh…
Disk-jet coupling across the spectral transition in supermassive black holes
Jia-Lai Kang, Chris Done, Scott Hagen +5
Accretion flows in both stellar and supermassive black holes show a distinct spectral transition. This is seen directly in binaries and changing look AGN, and also in a recent samp…
