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…
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…
BASS XXXII: Studying the Nuclear Mm-wave Continuum Emission of AGNs with ALMA at Scales 100-200 pc
Taiki Kawamuro, Claudio Ricci, Masatoshi Imanishi +25
To understand the origin of nuclear ( 100 pc) millimeter-wave (mm-wave) continuum emission in active galactic nuclei (AGNs), we systematically analyzed sub-arcsec resolut…
AGN-driven Cold Gas Outflow of NGC 1068 Characterized by Dissociation-Sensitive Molecules
Toshiki Saito, Shuro Takano, Nanase Harada +11
Recent developments in (sub-)millimeter facilities have drastically changed the amount of information obtained from extragalactic spectral scans. In this paper, we present a featur…
High-resolution ALMA study of CO (2-1) line and dust continuum emissions in cluster galaxies at z = 1.46
Ryota Ikeda, Ken-ichi Tadaki, Daisuke Iono +11
We present new Atacama Large Millimeter/submillimeter Array (ALMA) results obtained from spatially resolved CO =2-1 line ( resolution) and 870 m continuum ( res…
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…
