A proto-cluster of massive quiescent galaxies at z=4
Masayuki Tanaka, Masato Onodera, Rhythm Shimakawa +7
We report on discovery of a concentration of massive quiescent galaxies located at z=4. The concentration is first identified using high-quality photometric redshifts based on deep…
New technique to select recent fast-quenching galaxies at using the optical colors
Mariko Kubo, Tohru Nagao, Hisakazu Uchiyama +4
Many massive quiescent galaxies have been discovered at thanks to multi-wavelength deep and wide surveys, however, substantial deep near-infrared spectroscopic observations a…
An enhanced abundance of bright galaxies in protocluster candidates at z~3-5
Jun Toshikawa, Stijn Wuyts, Nobunari Kashikawa +11
We present a protocluster search covering to based on the combination of the Hyper SuprimeCam Subaru Strategic Programme and the CFHT Large Area -band Deep Sur…
A massive quiescent galaxy in a group environment at
Takumi Kakimoto, Masayuki Tanaka, Masato Onodera +10
We report on the spectroscopic confirmation of a massive quiescent galaxy at in the COSMOS field. The object was first identified as a galaxy with suppressed…
Size - Stellar Mass Relation and Morphology of Quiescent Galaxies at in Public Fields
Kei Ito, Francesco Valentino, Gabriel Brammer +19
We present the results of a systematic study of the rest-frame optical morphology of quiescent galaxies at using the Near-Infrared Camera (NIRCam) onboard . Based…
Revisiting the Properties of X-ray AGN in the SSA22 Protocluster: Normal SMBH and Host-Galaxy Growth for AGN in a Overdensity
Erik B. Monson, Keith Doore, Rafael T. Eufrasio +6
We analyze the physical properties of 8 X-ray selected active galactic nuclei (AGN) and one candidate protoquasar system (ADF22A1) in the SSA22 protocluster by fitting t…
An Atlas of Color-selected Quiescent Galaxies at in Public Fields
Francesco Valentino, Gabriel Brammer, Katriona M. L. Gould +24
We present the results of a systematic search for candidate quiescent galaxies in the distant Universe in eleven fields with publicly available observations collected during…
COSMOS2020: Discovery of a protocluster of massive quiescent galaxies at
Kei Ito, Masayuki Tanaka, Francesco Valentino +9
Protoclusters of galaxies have been found in the last quarter century. However, most of them have been found through the overdensity of star-forming galaxies, and there had been no…
