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…
ALMA Observations of Lyman-alpha Blob 1: Multiple major-mergers and widely distributed interstellar media
Hideki Umehata, Ian Smail, Charles C. Steidel +11
We present observations of a giant Lyman-alpha blob in the SSA22 proto-cluster at z=3.1, SSA22-LAB1, taken with the Atacama Large Millimeter/submillimeter Array (ALMA). Dust contin…
A massive quiescent galaxy confirmed in a protocluster at z=3.09
Mariko Kubo, Hideki Umehata, Yuichi Matsuda +10
We report a massive quiescent galaxy at spectroscopically confirmed at a protocluster in the SSA22 field by detecting the Balmer and Ca {\fo…
On the Nature of AGN and Star Formation Enhancement in the SSA22 Protocluster: The HST WFC3 IR View
Erik B. Monson, Bret D. Lehmer, Keith Doore +9
We examine possible environmental sources of the enhanced star formation and active galactic nucleus (AGN) activity in the SSA22 protocluster using Hubble WFC3 F160W ($\…
Interrelation of the environment of Ly emitters and massive galaxies at
Kei Ito, Nobunari Kashikawa, Masayuki Tanaka +7
We present a comparison of the spatial distributions of Ly emitters (LAEs) and massive star-forming and quiescent galaxies (SFGs and QGs) at . We use the photometric re…
Faint Quasars Live in the Same Number Density Environments as Lyman Break Galaxies at z ~ 4
Hisakazu Uchiyama, Masayuki Akiyama, Jun Toshikawa +16
Characterizing high-z quasar environments is key to understanding the co-evolution of quasars and the surrounding galaxies. To restrict their global picture, we statistically exami…
