The X-ray statistical properties of dust-obscured galaxies detected by eROSITA

Akatoki Noboriguchi, Kohei Ichikawa, Yoshiki Toba +15

Dust-obscured galaxies (DOGs) are considered to be in a co-evolution phase, with the associated active galactic nuclei (AGN) obscured by dust and gas. Although the DOGs are thought…

An X-ray bright ERO hosting a type 2 QSO

P. Severgnini, A. Caccianiga, V. Braito +8

We present the XMM-Newton and the optical-VLT spectra along with the optical and the near-infrared photometric data of one of the brightest X-ray (F(2-10 keV)~1e-13 erg/s cm^2) ext…

Host Galaxies of the High-redshift AGNs in the GOODS Fields

Masayuki Akiyama

The star-formation rates and the stellar masses of the host galaxies of AGNs at high-redshifts are keys to understanding the evolution of the relation between the mass of the spher…

Down-Sizing in Galaxy Formation at z~1 in the Subaru/XMM-Newton Deep Survey (SXDS)

Tadayuki Kodama

We use the deep wide-field optical imaging data of the Subaru/XMM-Newton Deep Survey (SXDS) to discuss the luminosity (mass) dependent galaxy colours down to z'=25.0 (5 x 10^9 h_{7…

Deep-Imaging Observations of a Candidate of an Absorbed QSO at z=0.653, AX J131831+3341

M. Akiyama, K. Ohta, N. Tamura +12

The results of deep-imaging observations of a candidate of an absorbed QSO at z=0.653, AX J131831+3341, are presented. AX J131831+3341 was found during the course of optical follow…
