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…
H1821+643: The most X-ray and infrared luminous AGN in the Swift/BAT survey in the process of rapid stellar and supermassive black hole mass assembly
Hikaru Fukuchi, Kohei Ichikawa, Masayuki Akiyama +6
H1821+643 is the most X-ray luminous non-beamed AGN of erg s in the Swift/BAT ultra-hard X-ray survey and it is also a hyper-lumin…
The Kiloparsec-scale Neutral Atomic Carbon Outflow in the Nearby Type-2 Seyfert Galaxy NGC 1068: Evidence for Negative AGN Feedback
Toshiki Saito, Shuro Takano, Nanase Harada +13
Active galactic nucleus (AGN) feedback is postulated as a key mechanism for regulating star formation within galaxies. Studying the physical properties of the outflowing gas from A…
On the Connection between Supermassive Black Hole and Galaxy Growth in the Reionization Epoch
Junyao Li, John D. Silverman, Takuma Izumi +6
The correlation between the mass of supermassive black holes (SMBHs; ) and their host galaxies () in the reionization epoch provides valuab…
Extremely Buried Nucleus of IRAS 172080014 Observed at Sub-Millimeter and Near-Infrared Wavelengths
Shunsuke Baba, Masatoshi Imanishi, Takuma Izumi +6
The ultraluminous infrared galaxy IRAS 172080014 is a late-stage merger that hosts a buried active galactic nucleus (AGN). To investigate its nuclear structure, we performed hig…
The MBHBM Project -- II. Molecular Gas Kinematics in the Lenticular Galaxy NGC 3593 Reveal a Supermassive Black Hole
Dieu D. Nguyen, Martin Bureau, Sabine Thater +15
As part of the Measuring Black Holes in Below Milky Way-mass (M) galaxies (MBHBM) Project, we present a dynamical measurement of the supermassive black hole (SMBH)…
