Accurate Determination of Chemical Abundances near a Supermassive Black Hole
The XRISM collaboration
The metal abundances in galactic nuclei carry key information on the history of star formation and mass transfer in central regions of galaxies. X-ray fluorescence analysis is a un…
IMPACTX: An X-ray Spectral Model for Polar Dust and Clumpy Torus
Kanta Fujiwara, Yoshihiro Ueda, Shoji Ogawa +2
We construct a generic X-ray spectral model for the reflection component from the clumpy torus and dusty gas in the polar region (polar dusty gas) in an active galactic nucleus (AG…
ALMA Lensing Cluster Survey: Molecular Gas Properties of Line-Emitting Galaxies from a Blind Survey
Kanako Narita, Bunyo Hatsukade, Seiji Fujimoto +16
We present results of a blind search for line-emitting galaxies using ALMA Lensing Cluster Survey data. We detected seven line emitters, one of which is [C\,{\sc ii}] at $z = 6.071…
AGN outflows and their properties in Mrk 766 as revealed by KOOLS-IFU on the Seimei Telescope
Kyuseok Oh, Yoshihiro Ueda, Satoshi Yamada +10
We present the emission-line flux distributions and their ratios, as well as the gas outflow features, of the innermost 2 kpc region of the type 1 Seyfert galaxy Mrk 766, using the…
ALMA Lensing Cluster Survey: Physical characterization of near-infrared-dark intrinsically faint ALMA sources at z=2-4
Akiyoshi Tsujita, Kotaro Kohno, Shuo Huang +33
We present results from Atacama Large Millimeter/submillimeter Array (ALMA) spectral line-scan observations at 3-mm and 2-mm bands of three near-infrared-dark (NIR-dark) galaxies b…
ALMA/SCUBA-2 COSMOS Survey: Properties of X-ray- and SED-selected AGNs in Bright Submillimeter Galaxies
Ryosuke Uematsu, Yoshihiro Ueda, David M. Alexander +11
We investigate the properties of active galactic nuclei (AGNs) in the brightest submillimeter galaxies (SMGs) in the COSMOS field. We utilize the bright sample of ALMA/SCUBA-2 COSM…
