Statistical studies of X-ray selected Active Galactic Nuclei (AGN) indicate that the fraction of obscured AGN increases with increasing redshift, and the results suggest that a sig…
Finding of a population of active galactic nuclei showing a significant luminosity decline in the past yrs
J. Pflugradt, K. Ichikawa, M. Akiyama +4
Recent observations have revealed an interesting active galactic nuclei (AGN) subclass that shows strong activity at large scales ( kpc) but weaker at small scales ( pc…
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…
