Multiwavelength SED Analysis of X-Ray Selected AGNs at in Stripe 82 Region
Kenta Setoguchi, Yoshihiro Ueda, Yoshiki Toba +3
We perform a systematic, multiwavelength spectral energy distribution (SED) analysis of X-ray detected Active Galactic Nuclei (AGNs) at with SDSS counterparts in the St…
Apparent effect of dust extinction on the observed outflow velocity of ionized gas in galaxy mergers
Naomichi Yutani, Yoshiki Toba, Keiichi Wada
In this study, we examine photoionization outflows during the late stages of galaxy mergers, with a specific focus on the relation between observed velocity of outflowing gas and t…
Black hole mass and Eddington ratio distributions of less-luminous quasars at in the Subaru Hyper Suprime-Cam Wide field
Wanqiu He, Masayuki Akiyama, Motohiro Enoki +11
We investigate the black hole mass function (BHMF) and Eddington ratio distribution function (ERDF) of broad-line AGNs at z=4, based on a sample of 52 quasars with i<23.2 at 3.50 <…
Subaru High- Exploration of Low-luminosity Quasars (SHELLQs). XVII. Black Hole Mass Distribution at Estimated via Spectral Comparison with Low- Quasars
Ayumi Takahashi, Yoshiki Matsuoka, Masafusa Onoue +9
We report the distribution of black hole (BH) masses and Eddingont ratios estimated for a sample of 131 low luminosity quasars in the early cosmic epoch (). Our work…
New technique to select recent fast-quenching galaxies at using the optical colors
Mariko Kubo, Tohru Nagao, Hisakazu Uchiyama +4
Many massive quiescent galaxies have been discovered at thanks to multi-wavelength deep and wide surveys, however, substantial deep near-infrared spectroscopic observations a…
A new discovery space opened by eROSITA: Ionised AGN outflows from X-ray selected samples
Blessing Musiimenta, Marcella Brusa, Teng Liu +21
In the context of an evolutionary model, the outflow phase of an Active Galactic Nuclei (AGN) occurs at the peak of its activity, once the central SMBH is massive enough to generat…
