BASS XLI: the correlation between Mid-infrared emission lines and Active Galactic Nuclei emission
M. Bierschenk, C. Ricci, M. J. Temple +22
We analyze the Spitzer spectra of 140 active galactic nuclei (AGN) detected in the hard X-rays (14-195 keV) by the Burst Alert Telescope (BAT) on board Swift. This sample allows us…
Ongoing and fossil large-scale outflows detected in a high-redshift radio galaxy: [C II] observations of TN J09242201 at
Kianhong Lee, Masayuki Akiyama, Kotaro Kohno +13
We present Atacama Large Millimeter/submillimeter Array observations of the [C II] 158 m line and the underlying continuum emission of TN J09242201, which is one of the most…
Observational Properties of AGN Obscuration During the Peak of Accretion Growth
Bovornpratch Vijarnwannaluk, Masayuki Akiyama, Malte Schramm +11
We investigated the gas obscuration and host galaxy properties of active galactic nuclei (AGN) during the peak of cosmic accretion growth of supermassive black holes (SMBHs) at red…
[O IV] and [Ne V]-weak AGNs Hidden by Compton-thick Material in Late Mergers
Satoshi Yamada, Yoshihiro Ueda, Taiki Kawamuro +10
We study "buried" active galactic nuclei (AGNs) almost fully covered by circumnuclear material in ultra-/luminous infrared galaxies (U/LIRGs), which show weak ionized lines from na…
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 <…
Origin of an Orbiting Star Around the Galactic Supermassive Black Hole
Shogo Nishiyama, Tomohiro Kara, Brian Thorsbro +6
The tremendous tidal force that is linked to the supermassive black hole (SMBH) at the center of our galaxy is expected to strongly subdue star formation in its vicinity. Stars wit…
