No Evidence for Variability of Intervening Absorption Lines toward GRB 060206: Implications for the Mg II Incidence Problem
Kentaro Aoki, Tomonori Totani, Takashi Hattori +6
We examine variability of absorption line strength of intervening systems along the line of sight to GRB 060206 at , by the low-resolution optical spectra obtained by the…
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 Cosmic MeV Gamma-ray Background and Hard X-ray Spectra of Active Galactic Nuclei: Implications for the Origin of Hot AGN Coronae
Yoshiyuki Inoue, Tomonori Totani, Yoshihiro Ueda
The origin of the extragalactic gamma-ray background radiation at 1-10 MeV is still unknown. Although the cosmic X-ray background (CXB) up to a few hundreds keV can be accounted fo…
Supernovae in the Subaru Deep Field: An Initial Sample, and Type Ia Rate, out to Redshift 1.6
Dovi Poznanski, Dan Maoz, Naoki Yasuda +12
Large samples of high-redshift supernovae (SNe) are potentially powerful probes of cosmic star formation, metal enrichment, and SN physics. We present initial results from a new de…
Intracluster Short Gamma-Ray Bursts by Compact Binary Mergers
Yuu Niino, Tomonori Totani
One of the possible origins of short gamma-ray bursts (SGRBs) is merging of compact binaries, and the effect of large kick velocity is a signature that can be used as an observatio…
