ALMA Observations for CO Emission from Luminous Lyman-break Galaxies at -

Yoshiaki Ono, Seiji Fujimoto, Yuichi Harikane +14

We present our new Atacama Large Millimeter/submillimeter Array (ALMA) observations targeting CO(6-5) emission from three luminous Lyman break galaxies (LBGs) at $z_{\rm spec} = 6.…

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…

The Obscured Fraction of Quasars at Cosmic Noon

Bovornpratch Vijarnwannaluk, Masayuki Akiyama, Malte Schramm +6

Statistical studies of X-ray selected Active Galactic Nuclei (AGN) indicate that the fraction of obscured AGN increases with increasing redshift, and the results suggest that a sig…

Deciphering the extreme X-ray variability of the nuclear transient eRASSt J045650.3-203750: A likely repeating partial tidal disruption event

Zhu Liu, A. Malyali, M. Krumpe +17

(Abridged) In this paper, we present the results of an exceptional repeating X-ray nuclear transient, eRASSt J045650.3-203750 (hereafter J0456-20), uncovered by SRG/eROSITA in a qu…

Exploratory Study of Transverse Proximity Effect around BAL Quasars

Toru Misawa, Rikako Ishimoto, Satoshi Kobu +5

We aim to find out the reason why there exists an anisotropic HI absorption around quasars; i.e., the environments around quasars are highly biased toward producing strong HI absor…
