The most characteristic high-energy phenomena in the Galactic center (GC) region is the presence of strong K-shell emission lines from highly ionized Si, S, Ar, Ca, Fe and Ni, whic…
ASTRO-H White Paper - Low-mass X-ray Binaries
C. Done, M. Tsujimoto, E. Cackett +20
There is still 10-20% uncertainty on the neutron star (NS) mass-radius relation. These uncertainties could be reduced by an order of magnitude through an unambiguous measure of M/R…
A fussy revisitation of antiprotons as a tool for Dark Matter searches
Mathieu Boudaud, Marco Cirelli, Gaëlle Giesen +1
Antiprotons are regarded as a powerful probe for Dark Matter (DM) indirect detection and indeed current data from PAMELA have been shown to lead to stringent constraints. However,…
A Suzaku view of IGR J16393-4643
Nazma Islam, Chandreyee Maitra, Pragati Pradhan +1
The pulsar IGR J16393-4643 belongs to a class of highly absorbed supergiant HMXBs, characterised by very high column density of absorbing matter. We present the results of the simu…
Jet-induced star formation by a microquasar
I. F. Mirabel, S. Chaty, L. F. Rodriguez +1
Theoretical and observational work show that jets from AGN can trigger star formation. However, in the Milky Way the first -and so far- only clear case of relativistic jets inducin…
Source identification in the IGR J17448-3232 field: discovery of the Scorpius galaxy cluster
Nicolas M. Barrière, John A. Tomsick, Daniel R. Wik +2
We use a 43-ks XMM-Newton observation to investigate the nature of sources first distinguished by a follow-up Chandra observation of the field surrounding INTEGRAL source IGR J1744…
Discovery of the VHE gamma-ray source HESS J1832-093 in the vicinity of SNR G22.7-0.2
H. E. S. S. Collaboration, :, A. Abramowski +218
The region around the supernova remnant (SNR) W41 contains several TeV sources and has prompted the H.E.S.S. Collaboration to perform deep observations of this field of view. This…
Gamma-ray flaring activity from the gravitationally lensed blazar PKS 1830-211 observed by Fermi LAT
The Fermi LAT Collaboration, A. A. Abdo, M. Ackermann +126
The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope routinely detects the highly dust-absorbed, reddened, and MeV-peaked flat spectrum radio quasar PKS 1830…

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…
The reflection of two past outbursts of Sagittarius A* observed by Chandra during the last decade
Maïca Clavel, R. Terrier, A. Goldwurm +4
The supermassive black hole at the Galactic center, Sagittarius A*, has experienced periods of higher activity in the past. The reflection of these past outbursts is observed in th…
