[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…
Probing the origin of the two-component structure of broad line region by reverberation mapping of an extremely variable quasar
Shumpei Nagoshi, Fumihide Iwamuro, Satoshi Yamada +5
The physical origins of quasar components, such as the broad line region (BLR) and dust torus, remain under debate. To gain insights into them, we focused on Changing-State Quasars…
ALMA Lensing Cluster Survey: Properties of Millimeter Galaxies Hosting X-ray Detected Active Galactic Nuclei
Ryosuke Uematsu, Yoshihiro Ueda, Kotaro Kohno +10
We report the multi-wavelength properties of millimeter galaxies hosting X-ray detected active galactic nuclei (AGNs) from the ALMA Lensing Cluster Survey (ALCS). ALCS is an extens…
Hard X-Ray to Radio Multiwavelength SED Analysis of Local U/LIRGs in GOALS Sample with Self-consistent AGN Model Including Polar-dust Component
Satoshi Yamada, Yoshihiro Ueda, Martín Herrera-Endoqui +7
We conduct a hard X-ray to radio multiwavelength spectral energy distribution (SED) decomposition for 57 local luminous and ultraluminous infrared galaxies (U/LIRGs) observed with…
Optical IFU Observations of GOALS Sample with KOOLS-IFU on Seimei Telescope: Initial results of 9 U/LIRGs at 0.04
Yoshiki Toba, Satoshi Yamada, Kazuya Matsubayashi +23
We present ionized gas properties of 9 local ultra/luminous infrared galaxies (U/LIRGs) at 0.04 through IFU observations with KOOLS-IFU on Seimei Telescope. The observed targ…
A hard X-ray view of Luminous and Ultra-luminous Infrared Galaxies in GOALS: I - AGN obscuration along the merger sequence
C. Ricci, G. C. Privon, R. W. Pfeifle +25
The merger of two or more galaxies can enhance the inflow of material from galactic scales into the close environments of Active Galactic Nuclei (AGN), obscuring and feeding the su…
