GRB 041006 was detected by HETE-2 at 12:18:08 UT on 06 October 2004. This GRB displays a soft X-ray emission, a precursor before the onset of the main event, and also a soft X-ray tail after the end...
HETE-2 Observations of the X-Ray Flash XRF 040916 (2007)
Arimoto, Makoto, Kawai, Nobuyuki, Yoshida, Atsumasa, Tamagawa, Toru, Shirasaki, Yuji, Suzuki, Motoko, ...
A long X-ray flash was detected and localized by the instruments aboard the High Energy Transient Explorer II (HETE-2) at 00:03:30 UT on 2004 September 16. The position was reported to the GRB...
A Comprehensive Study of Short Bursts from SGR 1806-20 and SGR 1900+14 Detected by HETE-2 (2007)
Nakagawa, Yujin E., Yoshida, Atsumasa, Hurley, Kevin, Atteia, Jean-Luc, Maetou, Miki, Tamagawa, Toru, ...
We present the results of temporal and spectral studies of the short burst (less than a few hundred milliseconds) from the soft gamma repeaters (SGRs) 1806-20 and 1900+14 using the HETE-2 samples. In...

An Optically Dark GRB Observed by HETE-2: GRB 051022 (2006)
Nakagawa, Yujin E., Yoshida, Atsumasa, Sugita, Satoshi, Tanaka, Kaoru, Ishikawa, Nobuyuki, Tamagawa, Toru, ...
GRB 051022 was detected at 13:07:58 on 22 October 2005 by HETE-2. The location of GRB 051022 was determined immediately by the flight localization system. This burst contains multiple pulses and has...
NGC 4151: an intrinsically average Seyfert 1 (2001)
Zdziarski, Andrzej A., Leighly, Karen M., Matsuoka, Masaru, Cappi, Massimo, Mihara, Tatehiro
We present a detailed analysis of a long, 100 ksec, observation of NGC 4151 by ASCA, contemporaneous with an observation by the CGRO/OSSE. We fit the data with physical models including an Fe K line...
X-ray Observations of the Broad-Line Radio Galaxy 3C 390.3 (1997)
Leighly, Karen M., O'Brien, Paul T., Edelson, Rick, George, Ian M., Malkan, Matthew A., Matsuoka, Masaru, ...
We present the data and preliminary analysis for a series of 90 ROSAT HRI and two ASCA observations of the broad-line radio galaxy 3C 390.3. These data were obtained during the period 1995 January 2...
Guainazzi, Matteo, Mihara, Tatehiro, Otani, Chiko, Matsuoka, Masaru
We present the results of an extensive analysis of the ``ASCA'' AO2 observation of the Seyfert 1 galaxy NGC4051. The target exhibits broadband [0.5--10 keV] variability by a factor $\sim 8$ on time...
