Temperature Structure in the Perseus Cluster Core Observed with Hitomi
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192
The present paper investigates the temperature structure of the X-ray emitting plasma in the core of the Perseus cluster using the 1.8--20.0 keV data obtained with the Soft X-ray S…
Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
D. Zaborov, A. M. Taylor, D. A. Sanchez +2
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies, providing new opportunities for studies of Active Ga…
Gamma-ray blazar spectra with H.E.S.S. II mono analysis: the case of PKS 2155-304 and PG 1553+113
H. E. S. S. Collaboration, :, H. Abdalla +332
The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies. The lowest energy threshold is obtained using monosc…
ASTRO-H White Paper - Shock and Acceleration
F. Aharonian, Y. Uchiyama, D. Khangulyan +4
We discuss the prospects for a progress to be brought by ASTRO-H in the understanding of the physics of particle acceleration in astrophysical environments. Particular emphasis wil…
ASTRO-H White Paper - Young Supernova Remnants
J. P. Hughes, S. Safi-Harb, A. Bamba +23
Thanks to the unprecedented spectral resolution and sensitivity of the Soft X-ray Spectrometer (SXS) to soft thermal X-ray emission, ASTRO-H will open a new discovery window for un…
ASTRO-H White Paper - Older Supernova Remnants and Pulsar Wind Nebulae
K. S. Long, A. Bamba, F. Aharonian +20
Most supernova remnants (SNRs) are old, in the sense that their structure has been profoundly modified by their interaction with the surrounding interstellar medium (ISM). Old SNRs…
The ASTRO-H X-ray Observatory
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +220
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will…
The structure and emission model of the relativistic jet in the quasar 3C 279 inferred from radio to high-energy gamma-ray observations in 2008-2010
M. Hayashida, G. M. Madejski, K. Nalewajko +90
We present time-resolved broad-band observations of the quasar 3C 279 obtained from multi-wavelength campaigns conducted during the first two years of the Fermi Gamma-ray Space Tel…
The cosmic-ray and gas content of the Cygnus region as measured in gamma rays by the Fermi Large Area Telescope
the Fermi LAT Collaboration
The Cygnus region hosts a giant molecular-cloud complex which actively forms massive stars. Interactions of cosmic rays with interstellar gas and radiation fields make it shine at…
Fermi Large Area Telescope Observations of the Cygnus Loop Supernova Remnant
H. Katagiri, L. Tibaldo, J. Ballet +7
We present an analysis of the gamma-ray measurements by the Large Area Telescope(LAT) onboard the \textit{Fermi Gamma-ray Space Telescope} in the region of the supernova remnant(SN…
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
Fermi LAT Collaboration
We report an analysis of the interstellar -ray emission in the third Galactic quadrant measured by the {Fermi} Large Area Telescope. The window encompassing the Galactic plane f…
A population of gamma-ray emitting globular clusters seen with the Fermi Large Area Telescope
The Fermi LAT collaboration
Globular clusters with their large populations of millisecond pulsars (MSPs) are believed to be potential emitters of high-energy gamma-ray emission. Our goal is to constrain the m…
Discovery of Diffuse Hard X-ray Emission around Jupiter with Suzaku
Yuichiro Ezoe, Kumi Ishikawa, Takaya Ohashi +4
We report the discovery of diffuse hard (1-5 keV) X-ray emission around Jupiter in a deep 160 ks Suzaku XIS data. The emission is distributed over ~16x8 Jovian radius and spatially…
