H.E.S.S. detection of TeV emission from the interaction region between the supernova remnant G349.7+0.2 and a molecular cloud
H. E. S. S. Collaboration, :, A. Abramowski +224
G349.7+0.2 is a young Galactic supernova remnant (SNR) located at the distance of 11.5 kpc and observed across the entire electromagnetic spectrum from radio to high energy (HE) Ga…
The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
ASTRO-H White Paper - Broad-band Spectroscopy and Polarimetry
P. Coppi, L. Stawarz, C. Done +13
The broad energy range spanned by ASTRO-H instruments, from ~0.3 to 600 keV, with its high spectral resolution calorimeter and sensitive hard X-ray imaging, offers unique opportuni…
ASTRO-H White Paper - New Spectral Features
R. K. Smith, H. Odaka, M. Audard +27
This white paper addresses selected new (to X-ray astronomy) physics and data analysis issues that will impact ASTRO-H SWG observations as a result of its high-spectral-resolution…
ASTRO-H White Paper - Accreting Pulsars, Magnetars, and Related Sources
S. Kitamoto, T. Enoto, S. Safi-Harb +18
As the endpoints of massive star evolution, neutron stars are enigmatic celestial objects characterized by extremely dense and exotic nuclear matter, magnetospheres with positrons…
H.E.S.S. reveals a lack of TeV emission from the supernova remnant Puppis A
H. E. S. S. Collaboration, :, A. Abramowski +224
Puppis A is an interesting ~4 kyr-old supernova remnant (SNR) that shows strong evidence of interaction between the forward shock and a molecular cloud. It has been studied in deta…
Diffuse Galactic gamma-ray emission with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +225
Diffuse -ray emission is the most prominent observable signature of celestial cosmic-ray interactions at high energies. While already being investigated at GeV energies over sev…
The high-energy -ray emission of AP Librae
H. E. S. S. Collaboration, Fermi-LAT collaborations
The -ray spectrum of the low-frequency-peaked BL Lac (LBL) object AP Librae is studied, following the discovery of very-high-energy (VHE; ) -ray emission up…
Search for dark matter annihilation signatures in H.E.S.S. observations of Dwarf Spheroidal Galaxies
H. E. S. S. Collaboration, :, A. Abramowski +229
Dwarf spheroidal galaxies of the Local Group are close satellites of the Milky Way characterized by a large mass-to-light ratio and are not expected to be the site of non-thermal h…
The origin of ultra-fast outflows in AGN: Monte-Carlo simulations of the wind in PDS 456
Kouichi Hagino, Hirokazu Odaka, Chris Done +4
Ultra-fast outflows (UFOs) are seen in many AGN, giving a possible mode for AGN feedback onto the host galaxy. However, the mechanism(s) for the launch and acceleration of these ou…
Discovery of Recombining Plasma in the Supernova Remnant 3C 391
Tamotsu Sato, Katsuji Koyama, Tadayuki Takahashi +2
Recent X-ray study of middle-aged supernova remnants (SNRs) reveals strong radiative recombination continua (RRCs) associated with overionized plasmas, of which the origin still re…
Long-term monitoring of PKS 2155304 with ATOM and H.E.S.S.: investigation of optical/-ray correlations in different spectral states
