A detailed study of massive galaxies in a protocluster at z=3.13
Ke Shi, Jun Toshikawa, Zheng Cai +2
We present a detailed study of Near-IR selected galaxies in a protocluster field at z = 3.13. Protocluster galaxies are selected using the available mutliwavelength data with the p…
Extended Lyman-alpha emission from a high-z DLA at z=3.115
Nobunari Kashikawa, Toru Misawa, Yosuke Minowa +5
We searched for star formation activity associated with high-z Damped Lyman-alpha systems (DLAs) with Subaru telescope. We used a set of narrow-band (NB) filters whose central wave…
A Ly-alpha Emitter with an Extremely Large Rest-frame Equivalent Width of ~900A at z=6.5: A Candidate of Population III-dominated Galaxy?
Nobunari Kashikawa, Tohru Nagao, Jun Toshikawa +13
We have identified a very interesting Ly-alpha emitter, whose Ly-alpha emission line has an extremely large observed equivalent width of EW_0=436^{+422}_{-149}A, which corresponds…
Discovery of a protocluster at z~6
Jun Toshikawa, Nobunari Kashikawa, Kazuaki Ota +10
We report the discovery of a protocluster at z~6 containing at least eight cluster member galaxies with spectroscopic confirmations in the wide-field image of the Subaru Deep Field…
Completing the Census of Ly-alpha Emitters at the Reionization Epoch
Nobunari Kashikawa, Kazuhiro Shimasaku, Yuichi Matsuda +16
We carried out extended spectroscopic confirmations of Ly-alpha emitters (LAEs) at z=6.5 and 5.7 in the Subaru Deep Field. Now, the total number of spectroscopically confirmed LAEs…
