Optical and Near-Infrared Photometric Observation during the Superoutburst of the WZ Sge-Type Dwarf Nova, V455 Andromedae (2009)

Matsui, R., Uemura, M., Arai, A., Sasada, M., Ohsugi, T., Yamashita, T., ...

We report on optical and infrared photometric observations of a WZ Sge-type dwarf nova, V455 And during a superoutburst in 2007. These observations were performed with the KANATA (V, J, and K_s...

Early phase observations of extremely luminous Type Ia Supernova 2009dc (2009)

Yamanaka, M., Kawabata, K. S., Kinugasa, K., Tanaka, M., Imada, A., Maeda, K., ...

We present early phase observations in optical and near-infrared wavelengths for the extremely luminous Type Ia supernova (SN Ia) 2009dc. The decline rate of the light curve is $\Delta...

The Interplanetary Network Supplement to the HETE-2 Gamma-Ray Burst Catalog (2009)

Hurley, K., Barraud, C., Pelangeon, A., Boer, M., Vanderspek, R., ...

Between 2000 November and 2006 May, one or more spacecraft of the interplanetary network (IPN) detected 226 cosmic gamma-ray bursts that were also detected by the FREGATE experiment aboard the...

Fermi/Large Area Telescope Discovery of Gamma-Ray Emission from a Relativistic Jet in the Narrow-Line Quasar PMN J0948+0022 (2009)

Abdo, A. A., Ackermann, M., Ajello, M., Axelsson, M., Baldini, L., Ballet, J., ...

We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope of high-energy γ-ray emission from the peculiar quasar PMN J0948+0022 (z = 0.5846). The optical...

X-ray Diagnostics of Thermal Conditions of the Hot Plasmas in the Centaurus Cluster (2009)

Takahashi, I., Kawaharada, M., Makishima, K., Matsushita, K., Fukazawa, Y., Ikebe, Y., ...

X-ray data of the Centaurus cluster, obtained with {\it XMM-Newton} for 45 ksec, were analyzed. Deprojected EPIC spectra from concentric thin shell regions were reproduced equally well by a...

Detection of Hard X-Rays from the Compton-Thick Seyfert 2 Galaxy NGC 2273 with Suzaku (2008)

Awaki, H., Terashima, Y., Higaki, Y., Fukazawa, Y.

We have obtained a broad-band spectrum of the Compton-thick Seyfert 2 galaxy NGC 2273 with Suzaku. The spectrum reveals the first detection of hard X-rays above ~10 keV from NGC 2273. The broad-band...

The NeXT Mission (2008)

Takahashi, T., Kelley, R., Mitsuda, K., Kunieda, H., Petre, R., White, N., ...

The NeXT (New exploration X-ray Telescope), the new Japanese X-ray Astronomy Satellite following Suzaku, is an international X-ray mission which is currently planed for launch in 2013. NeXT is a...

In-Orbit Performance of the Hard X-ray Detector on board Suzaku (2006)

Kokubun, M., Makishima, K., Takahashi, T., Murakami, T., Tashiro, M., Fukazawa, Y., ...

The in-orbit performance and calibration of the Hard X-ray Detector (HXD) on board the X-ray astronomy satellite Suzaku are described. Its basic performances, including a wide energy bandpass of...

Design and Performance of the Soft Gamma-ray Detector for the NeXT mission (2006)

Tajima, H., Kamae, T., Madejski, G., Mitani, T., Nakazawa, K., Tanaka, T., ...

The Soft Gamma-ray Detector (SGD) on board the NeXT (Japanese future high energy astrophysics mission) is a Compton telescope with narrow field of view (FOV), which utilizes Compton kinematics to...

A method for estimating optimal unrolling times for nested loops (1997)

A. Koseki, H. Komastu, Y. Fukazawa

Loop unrolling is one of the most promising paral-lelization techniques, because the nature of programs causes most of the processing time to be spent in their loops. Unrolling not only the innermost...
