[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…
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…
Comprehensive Broadband X-ray and Multiwavelength Study of Active Galactic Nuclei in Local 57 Ultra/luminous Infrared Galaxies Observed with NuSTAR and/or Swift/BAT
Satoshi Yamada, Yoshihiro Ueda, Atsushi Tanimoto +4
We perform a systematic X-ray spectroscopic analysis of 57 local ultra/luminous infrared galaxy systems (containing 84 individual galaxies) observed with Nuclear Spectroscopic Tele…
X-ray Constraint on Location of AGN Torus in Circinus Galaxy
Ryosuke Uematsu, Yoshihiro Ueda, Atsushi Tanimoto +5
The location of the obscuring "torus" in an active galactic nucleus (AGN) is still an unresolved issue. The line widths of X-ray fluorescence lines originated from the torus, parti…
NuSTAR Discovery of a Compton-thick Dust-obscured Galaxy WISE J0825+3002
Yoshiki Toba, Satoshi Yamada, Yoshihiro Ueda +6
We report the discovery of a Compton-thick (CT) dust-obscured galaxy (DOG) at = 0.89, WISE J082501.48+300257.2 (WISE0825+3002), observed by Nuclear Spectroscopic Telescope Arra…
Torus Constraints in ANEPD-CXO245: A Compton-thick AGN with Double-Peaked Narrow Lines
Takamitsu Miyaji, Martín Herrera-Endoqui, Mirko Krumpe +18
We report on the torus constraints of the Compton-thick AGN with double-peaked optical narrow line region (NLR) emission lines, ANEPD-CXO245, at z=0.449 in the AKARI NEP Deep Field…
A NuSTAR and XMM-Newton Study of the Two Most Actively Star-forming Green Pea Galaxies (SDSS J0749+3337 and SDSS J0822+2241)
Taiki Kawamuro, Yoshihiro Ueda, Kohei Ichikawa +4
We explore X-ray evidence for the presence of active galactic nuclei (AGNs) in the two most actively star-forming Green Pea galaxies (GPs), SDSS J0749+3337 and SDSS J0822+2241, whi…
Hard X-ray View of HCG 16 (Arp 318)
Saeko Oda, Yoshihiro Ueda, Atsushi Tanimoto +1
We report the hard X-ray (3-50 keV) view of the compact group HCG 16 (Arp 318) observed with Nuclear Spectroscopic Telescope Array (NuSTAR). NGC 838 and NGC 839 are undetected at e…
Shedding Light on the Compton-thick Active Galactic Nucleus in the Ultra-luminous Infrared Galaxy UGC 5101 with Broadband X-ray Spectroscopy
Saeko Oda, Atsushi Tanimoto, Yoshihiro Ueda +3
We report the broadband X-ray spectra of the ultra-luminous infrared galaxy (ULIRG) UGC 5101 in the 0.25-100 keV band observed with Swift/Burst Alert Telescope (BAT), NuSTAR, Suzak…
Suzaku Follow-up of Heavily Obscured Active Galactic Nuclei Detected in Swift/BAT Survey: NGC 1106, UGC 03752, and NGC 2788A
Atsushi Tanimoto, Yoshihiro Ueda, Taiki Kawamuro +1
We present the broadband (0.5-100 keV) spectra of three heavily obscured Active Galactic Nuclei (AGNs), NGC 1106, UGC 03752, and NGC 2788A, observed with Suzaku and Swift/Burst Ale…
