The Subaru/XMM-Newton Deep Survey (SXDS) - V. Optically Faint Variable Object Survey
Tomoki Morokuma, Mamoru Doi, Naoki Yasuda +19
We present our survey for optically faint variable objects using multi-epoch (8-10 epochs over 2-4 years) -band imaging data obtained with Subaru Suprime-Cam over 0.918 deg…
The Subaru/XMM-Newton Deep Survey (SXDS) - VI. Properties of Active Galactic Nuclei Selected by Optical Variability
Tomoki Morokuma, Mamoru Doi, Naoki Yasuda +11
We present the properties of active galactic nuclei (AGN) selected by optical variability in the Subaru/XMM-Newton Deep Field (SXDF). Based on the locations of variable components…
The Subaru/XMM-Newton Deep Survey (SXDS). IV. Evolution of Lya Emitters from z=3.1 to 5.7 in the 1 deg^2 Field: Luminosity Functions and AGN
Masami Ouchi, Kazuhiro Shimasaku, Masayuki Akiyama +13
We present luminosity functions (LFs) and various properties of Lya emitters (LAEs) at z=3.1, 3.7, and 5.7, in a 1 deg^2 sky of the Subaru/XMM-Newton Deep Survey (SXDS) Field. We o…
The Reionization and Galaxy Evolution Probed by z=7 Lyman Alpha Emitters
Kazuaki Ota, Masanori Iye, Nobunari Kashikawa +10
We made a narrowband NB973 (bandwidth of 200A at 9755A) imaging of the Subaru Deep Field (SDF) and found two z=7 Lyman alpha emitter (LAE) candidates down to NB973=24.9. Carrying o…
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…
Deep Spectroscopy of Systematically Surveyed Extended Lyman-alpha Sources at z~3-5
Tomoki Saito, Kazuhiro Shimasaku, Sadanori Okamura +4
Spatially extended Ly-alpha sources that are faint and/or compact in coninuum are candidates for extremely young (~< 10^7 yrs) galaxies at high redshifts. We present medium-resolut…
