AGN number fraction in galaxy groups and clusters at z < 1.4 from the Subaru Hyper Suprime-Cam survey
Aoi Hashiguchi, Yoshiki Toba, Naomi Ota +20
One of the key questions on active galactic nuclei (AGN) in galaxy clusters is how AGN could affect the formation and evolution of member galaxies and galaxy clusters in the histor…
Discovery of the lensed quasar eRASS1 J050129.5-073309 with eROSITA and
D. Tubín-Arenas, G. Lamer, M. Krumpe +9
We report the discovery and spectroscopic identification of the bright doubly lensed quasar eRASS1 J050129.5-073309 at redshift , selected from the first all-sky survey of…
Multicolor and multi-spot observations of Starlink's Visorsat
Takashi Horiuchi, Hidekazu Hanayama, Masatoshi Ohishi +25
This study provides the results of simultaneous multicolor observations for the first Visorsat (STARLINK-1436) and the ordinary Starlink satellite, STARLINK-1113 in the , , $…
JWST and ALMA imaging of dust-obscured, massive substructures in a typical star-forming disk galaxy
Wiphu Rujopakarn, Christina C. Williams, Emanuele Daddi +8
We present an identification of dust-attenuated star-forming galactic-disk substructures in a typical star-forming galaxy (SFG), UDF2, at . To date, substructures contai…
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…
Discovery of the luminous X-ray ignition eRASSt J234402.9352640; I. Tidal disruption event or a rapid increase in accretion in an active galactic nucleus?
D. Homan, M. Krumpe, A. Markowitz +17
In November 2020, a new, bright object, eRASSt J234402.9352640, was discovered in the second all-sky survey of SRG/eROSITA. The object brightened by a factor of at least 150 in…
