Searching for a Companion Star of Tycho's Type Ia Supernova with Optical Spectroscopic Observations
Yutaka Ihara, Jin Ozaki, Mamoru Doi +4
We report our first results of photometric and spectroscopic observations for Tycho's supernova remnant (SNR Tycho) to search for the companion star of a type Ia supernova (SN Ia).…
Wide-field Survey around Local Group Dwarf Spheroidal Galaxy Leo II: Spatial Distribution of Stellar Content
Yutaka Komiyama, Mamoru Doi, Hisanori Furusawa +12
We carried out a wide-field V, I imaging survey of the Local Group dwarf spheroidal galaxy Leo II using the Subaru Prime Focus Camera on the 8.2-m Subaru Telescope. The survey cove…
SuprimeCam Observation of Sporadic Meteors during Perseids 2004
M. Iye, M. Tanaka, M. Yanagisawa +6
We report the serendipitous findings of 13 faint meteors and 44 artificial space objects by Subaru SuprimeCam imaging observations during 11-16 August 2004. The meteors, at about 1…
A Subaru/Suprime-Cam Survey of M31's spheroid along the South-East minor axis
Mikito Tanaka, Masashi Chiba, Yutaka Komiyama +2
We have used Suprime-Cam on the Subaru Telescope to conduct a V- and I-band imaging survey of fields sampling the spheroid of the Andromeda galaxy along its south-east minor axis.…
The First Release COSMOS Optical and Near-IR Data and Catalog
P. Capak, H. Aussel, M. Ajiki +54
We present imaging data and photometry for the COSMOS survey in 15 photometric bands between 0.3um and 2.4um. These include data taken on the Subaru 8.3m telescope, the KPNO and CT…
The Habitat Segregation between Lyman Break Galaxies and Lyman alpha Emitters around a QSO at z~5
Nobunari Kashikawa, Tetsu Kitayama, Mamoru Doi +3
We carried out a target survey for Lyman break galaxies (LBGs) and Lyman alpha emitters (LAEs) around QSO SDSS J0211-0009 at z=4.87. The deep and wide broadband and narrowband imag…
