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…

Resolving galactic-scale obscuration of X-ray AGN at with COSMOS-Web

John D. Silverman, Vincenzo Mainieri, Xuheng Ding +25

A large fraction of the accreting supermassive black hole population is shrouded by copious amounts of gas and dust, particularly in the distant () Universe. While much…

eROSITA Final Equatorial-Depth Survey (eFEDS): eFEDS X-ray view of WERGS Radio Galaxies selected by the Subaru/HSC and VLA/FIRST survey

Kohei Ichikawa, Takuji Yamashita, Andrea Merloni +19

We construct the eROSITA X-ray catalog of radio galaxies discovered by the WERGS survey that is made by the cross-matching of the wide-area Subaru/HSC optical survey and VLA/FIRST…

Keck, Gemini, and Palomar 200-inch visible photometry of red and very-red Neptunian Trojans

B. T. Bolin, C. Fremling, A. Morbidelli +9

Neptunian Trojans (NTs), trans-Neptunian objects in 1:1 mean-motion resonance with Neptune, are generally thought to have been captured from the original trans-Neptunian protoplane…

Overmassive black holes in dwarf galaxies out to z0.9 in the VIPERS survey

M. Mezcua, M. Siudek, H. Suh +3

Supermassive black holes (SMBHs) are thought to originate from early Universe seed black holes of mass -10 M and grown through cosmic time. S…

A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). IV. Rapidly Growing (Super-)Massive Black Holes in Extremely Radio-Loud Galaxies

Kohei Ichikawa, Takuji Yamashita, Yoshiki Toba +19

We present the optical and infrared properties of 39 extremely radio-loud galaxies discovered by cross-matching the Subaru/Hyper Suprime-Cam (HSC) deep optical imaging survey and V…
