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…

Serendipitous Discovery of an Optically-Dark Ultra-Luminous Infrared Galaxy at = 3.4

N. H. Hayatsu, Zhi-Yu Zhang, R. J. Ivison +10

Dusty, submillimeter-selected galaxies without optical counterparts contribute a non-negligible fraction of the star formation in the early universe. However, such a population is…

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…

Age dependence of Lyα escape fraction of Lyα emitters and their significant role in cosmic reionization

Shunta Shimizu, Nobunari Kashikawa, Satoshi Kikuta +4

We study the Ly escape fraction, of Ly emitters (LAEs) identified by Subaru/HSC narrowband imaging at , using publicly availabl…
