Dust-obscured Galaxies with Broken Power-law Spectral Energy Distributions Discovered by UNIONS
Taketo Yoshida, Tohru Nagao, Yoshiki Toba +11
We report on the spectral energy distributions (SEDs) of infrared-bright dust-obscured galaxies (DOGs) with . Using photometry from the deep and wide…
J1406+0102: Dust Obscured Galaxy Hiding Super Eddington Accretion System with Bright Radio Emission
Hikaru Fukuchi, Kohei Ichikawa, Masayuki Akiyama +7
Recent high- quasar observations strongly indicate that super-Eddington accretion is a crucial phase to describe the presence of supermassive black holes (SMBHs) with $M_\mathrm…
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…
A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). X. The Massive and Passive Nature of Radio Galaxies at
Yuta Yamamoto, Tohru Nagao, Takuji Yamashita +8
High- radio galaxies (HzRGs) are considered important objects for understanding the formation and evolution of massive galaxies in the early universe. However, till date, detail…
Environments around quasars at 3 revealed by wide-field imaging with Subaru HSC and CFHT
Yuta Suzuki, Hisakazu Uchiyama, Yoshiki Matsuoka +7
We examine the local density environments around 67 quasars at , by combining the imaging data of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) and Canada-France-Haw…
