The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125 (2008)
Updike, Adria C., Haislip, Joshua B., Nysewander, Melissa C., Fruchter, Andrew S., Kann, D. Alexander, Klose, Sylvio, ...
We report on multi-wavelength observations, ranging from the X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the presence of absorption...

We have performed a joint analysis of prompt emission from four bright short gamma-ray bursts (GRBs) with the Suzaku-WAM and the Konus-Wind experiments. This joint analysis allows us to investigate...
Observations of the Prompt Gamma-Ray Emission of GRB 070125 (2007)
Bellm, Eric C., Hurley, Kevin, Pal'shin, Valentin, Yamaoka, Kazutaka, Bandstra, Mark S., Boggs, Steven E., ...
The long, bright gamma-ray burst GRB 070125 was localized by the Interplanetary Network. We present light curves of the prompt gamma-ray emission as observed by Konus-WIND, RHESSI, Suzaku-WAM, and...
Yonetoku, Daisuke, Tanabe, Sachiko, Murakami, Toshio, Emura, Naomi, Aoyama, Yuka, Kidamura, Takashi, ...
We observed an X-ray afterglow of GRB 060904A with the Swift and Suzaku satellites. We found rapid spectral softening during both the prompt tail phase and the decline phase of an X-ray flare in the...
Urata, Yuji, Yamazaki, Ryo, Sakamoto, Takanori, Huang, Kuiyun, Zheng, Weikang, Sato, Goro, ...
We study the ``normal'' decay phase of the X-ray afterglows of gamma-ray bursts (GRBs), which follows the shallow decay phase, using the events simultaneously observed in the R-band. The classical...
A multi band study of the optically dark GRB 051028 (2007)
Urata, Yuji, Huang, Kui-Yun, Kuo, Ping-Hung, Ip, Wing-Huen, Qiu, Yulei, Masuno, Keisuke, ...
Observations were made of the optical afterglow of GRB 051028 with the Lulin observatory's 1.0 m telescope and the WIDGET robotic telescope system. R band photometric data points were obtained on...
The X-ray observatory Suzaku (2007)
Mitsuda, Kazuhisa, Bautz, Mark, Inoue, Hajime, Kelley, Richard L., Koyama, Katsuji, Kunieda, Hideyo, ...
Ota, Naomi, Fukazawa, Yasushi, Fabian, Andrew C., Kanemaru, Takehiro, Kawaharada, Madoka, Kawano, Naomi, ...
The Centaurus cluster (z=0.0104) was observed with the X-ray Imaging Spectrometer (XIS) onboard the Suzaku X-ray satellite in three pointings, one centered on the cluster core and the other two...
Matsushita, Kyoko, Fukazawa, Yasushi, Hughes, John P., Kitaguchi, Takao, Makishima, Kazuo, Nakazawa, Kazuhiro, ...
The metallicity distribution in the Fornax cluster was studied with the XIS instrument onboard the Suzaku satellite. K-shell lines of O and Mg were resolved clearly, and the abundances of O, Mg, Si,...
Subaru optical observations of the two middle-aged pulsars PSR B0656+14 and Geminga (2005)
Shibanov, Yuri A., Zharikov, Sergei V., Komarova, Viktoria N., Kawai, Nobuyuki, Urata, Yuji, Koptsevich, Alexey B., ...
We carried out a deep subarcsecond BRI imaging of the two middle-aged pulsars to establish their properties in the optical range. Both pulsars are detected at >10 sigma level. Geminga is for the...
