Exponentially Decaying Extended Emissions Following Short Gamma-Ray Bursts with Possible Luminosity -- E-folding Time Correlation
Yasuaki Kagawa, Daisuke Yonetoku, Tatsuya Sawano +3
The origin of extended emissions following prompt emissions of short gamma-ray bursts (SGRBs) is in mystery. The long-term activity of the extended emission is responsible for prom…
Systematic study for gas-to-dust ratio of short gamma-ray burst afterglows
Kazuki Yoshida, Daisuke Yonetoku, Makoto Arimoto +2
Extra-galactic X-ray absorption and optical extinction are often found in gamma-ray burst (GRB) afterglows and they could be tracers of both circumburst and host galaxy environment…
Development of wide-field low-energy X-ray imaging detectors for HiZ-GUNDAM
Kazuki Yoshida, Daisuke Yonetoku, Tatsuya Sawano +9
We are planning a future gamma-ray burst (GRB) mission HiZ-GUNDAM to probe the early universe beyond the redshift of z > 7. Now we are developing a small prototype model of wide-fi…
X-raying extended emission and rapid decay of short gamma-ray bursts
Yasuaki Kagawa, Daisuke Yonetoku, Tatsuya Sawano +5
Extended emission is a mystery in short gamma-ray bursts (SGRBs). By making time resolved spectral analyses of brightest nine events observed by XRT, we obviously cla…
High-z gamma-ray bursts for unraveling the dark ages mission HiZ-GUNDAM
Daisuke Yonetoku, Tatehiro Mihara, Tatsuya Sawano +28
We are now investigating and studying a small satellite mission HiZ-GUNDAM for future observation of gamma-ray bursts (GRBs). The mission concept is to probe "the end of dark ages…
