Nobunari Kashikawa,Kazuhiro Shimasaku,Matthew A. Malkan,Mamoru Doi,Yuichi Matsuda,Masami Ouchi,Yoshiaki Taniguchi,Chun Ly,Tohru Nagao,Masanori Iye,Kentaro Motohara,Takashi Murayama,Kouji Murozono,Kyoji Nariai,Kouji Ohta,Sadanori Okamura,Toshiyuki Sasaki,Yasuhiro Shioya,Masayuki Umemura +18 more
TL;DR: In this article, an extensive search for Lyα emitters (LAEs) at z = 6.5 in the Subaru Deep Field was conducted, which revealed an apparent deficit at the bright end of ∼ 0.75 mag fainter L*, compared with that observed at z=5.7.

TL;DR: In this paper, a 64-night spectroscopic monitoring campaign at the Lick Observatory 3m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0: 05) Seyfert 1 galaxies with expected masses in the range of 10 6 -10 7, and also the well-studied nearby active galactic nucleus (AGN) NGC 5548.

TL;DR: In this article, a 64-night spectroscopic monitoring campaign at the Lick Observatory 3m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0.05) Seyfert 1 galaxies with expected masses in the range ~10^6-10^7 M_sun and also the well-studied nearby active galactic nucleus (AGN) NGC 5548.
Journal ArticleDOI
The peculiar type Ia SN 1991T : detonation of a white dwarf ?
Alexei V. Filippenko,Michael Richmond,Thomas Matheson,Joseph C. Shields,E. Margaret Burbidge,Ross D. Cohen,Mark Dickinson,Matthew A. Malkan,Brant O. Nelson,Jochen Pietz,David J. Schlegel,Patrick Schmeer,Hyron Spinrad,Charles C. Steidel,Hien D. Tran,William Wren +15 more
TL;DR: SN 1991T was a peculiar object whose premaximum optical spectrum did not resemble that of any known supernova; it appears to have been dominated by lines of iron-group elements.
Journal ArticleDOI
Lyα Emitters at z = 5.7 in the Subaru Deep Field
Kazuhiro Shimasaku,Nobunari Kashikawa,Mamoru Doi,Chun Ly,Matthew A. Malkan,Yuichi Matsuda,Masami Ouchi,Tomoki Hayashino,Masanori Iye,Kentaro Motohara,Takashi Murayama,Tohru Nagao,Kouji Ohta,Sadanori Okamura,Toshiyuki Sasaki,Yasuhiro Shioya,Yoshiaki Taniguchi +16 more
TL;DR: Shimasaku et al. as discussed by the authors measured rest-frame Lyα equivalent widths (EWs) for the confirmed LAEs, to find that the median among the 28 objects satisfying the photometric selection criteria is W i0 = 233 ˚ A.
