Probing dipolar power asymmetry with galaxy clustering and intrinsic alignments
Keita Minato, Atsushi Taruya, Teppei Okumura +1
We investigate the prospects for probing large-scale statistical anisotropy through galaxy clustering and intrinsic alignments (IA) in Stage IV galaxy surveys. Specifically, we con…
The X-ray statistical properties of dust-obscured galaxies detected by eROSITA
Akatoki Noboriguchi, Kohei Ichikawa, Yoshiki Toba +15
Dust-obscured galaxies (DOGs) are considered to be in a co-evolution phase, with the associated active galactic nuclei (AGN) obscured by dust and gas. Although the DOGs are thought…
Discovery of merging twin quasars at z = 6.05
Yoshiki Matsuoka, Takuma Izumi, Masafusa Onoue +14
We report the discovery of two quasars at a redshift of = 6.05, in the process of merging. They were serendipitously discovered from the deep multi-band imaging data collected…
Quasar Luminosity Function at z = 7
Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa +41
We present the quasar luminosity function (LF) at , measured with 35 spectroscopically confirmed quasars at . The sample of 22 quasars from the Subaru High-…
eROSITA Final Equatorial-Depth Survey (eFEDS): eFEDS X-ray view of WERGS Radio Galaxies selected by the Subaru/HSC and VLA/FIRST survey
Kohei Ichikawa, Takuji Yamashita, Andrea Merloni +19
We construct the eROSITA X-ray catalog of radio galaxies discovered by the WERGS survey that is made by the cross-matching of the wide-area Subaru/HSC optical survey and VLA/FIRST…
Extreme nature of four blue-excess dust-obscured galaxies revealed by optical spectroscopy
Akatoki Noboriguchi, Tohru Nagao, Yoshiki Toba +13
We report optical spectroscopic observations of four blue-excess dust-obscured galaxies (BluDOGs) identified by Subaru Hyper Suprime-Cam. BluDOGs are a sub-class of dust-obscured g…
