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 Lensing Cluster Survey: Full SED Analysis of z~0.5-6 Lensed Galaxies Detected with Millimeter Observations
Ryosuke Uematsu, Yoshihiro Ueda, Kotaro Kohno +17
Sub/millimeter galaxies are a key population for the study of galaxy evolution because the majority of star formation at high redshifts occurred in galaxies deeply embedded in dust…
[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…

We perform a systematic, multiwavelength spectral energy distribution (SED) analysis of X-ray detected Active Galactic Nuclei (AGNs) at with SDSS counterparts in the St…
Circumnuclear Multi-phase Gas in the Circinus Galaxy. V. The Origin of the X-Ray Polarization in the Circinus Galaxy
Atsushi Tanimoto, Keiichi Wada, Yuki Kudoh +3
The Imaging X-ray Polarimetry Explorer (IXPE) detected X-ray polarization in the nearest Seyfert 2 galaxy, the Circinus galaxy, for the first time. To reproduce the IXPE results, w…
Broadband X-ray Spectral Study of Nuclear Structure in Local Obscured Radio Galaxies
Yuya Nakatani, Yoshihiro Ueda, Claudio Ricci +6
Radio galaxies are a key population to understand the importance of relativistic jets in AGN feedback. We present the results of a systematic, broadband X-ray spectral analysis of…
