Time-evolution of Peak Energy and Luminosity Relation within Pulses for GRB 061007: Probing Fireball Dynamics

Masanori Ohno, Kunihito Ioka, Kazutaka Yamaoka +3

We perform a time-resolved spectral analysis of bright, long Gamma-ray burst GRB 061007 using Suzaku/WAM and Swift/BAT. Thanks to the large effective area of the WAM, we can invest…

Fermi LAT Observations of the Vela Pulsar

A. A. Abdo

The Vela pulsar is the brightest persistent source in the GeV sky and thus is the traditional first target for new gamma-ray observatories. We report here on initial Fermi Large Ar…

Stationary isothermic surfaces and some characterizations of the hyperplane in the N-dimensional Euclidean space

Rolando Magnanini, Shigeru Sakaguchi

We consider an entire graph S of a continuous real function over (N-1)-dimensional Euclidean space with N larger than or equal to 3. Let D be a domain in N-dimensional Euclidean sp…

Electron acceleration at a low-Mach-number perpendicular collisionless shock

Takayuki Umeda, Masahiro Yamao, Ryo Yamazaki

A full particle simulation study is carried out on the electron acceleration at a collisionless, relatively low Alfven Mach number (M_A=5), perpendicular shock. Recent self-consist…

Hard X-ray Properties of the Merging Cluster Abell 3667 as Observed with Suzaku

Kazuhiro Nakazawa, Craig L. Sarazin, Madoka Kawaharada +10

Wide-band Suzaku data on the merging cluster Abell 3667 were examined for hard X-ray emission in excess to the known thermal component. Suzaku detected X-ray signals in the wide en…

Detection of Polarimetric Variations Associated with the Shortest Time-Scale Variability in S5 0716714

Mahito Sasada, Makoto Uemura, Akira Arai +7

We present the result of near-infrared and optical observations of the BL Lac object S5 0716714 carried out by the KANATA telescope. S5 0716714 has both a long term high-…
