89. VERITAS Galactic Physics

The VERITAS array of four imaging atmospheric Cherenkov telescopes, located at the Fred Lawrence Whipple observatory in southern Arizona, has been in full operation since September 2007. Sensitive in the ~80 GeV to 30 TeV regime, VERITAS has recently (Summer 2012) completed a full array upgrade including the installation of new high quantum efficiency photomultiplier cameras. VERITAS has...

90. The TeV Gamma-ray Milky Way as seen by H.E.S.S.

H.E.S.S. is an imaging Cherenkov telescope array in Namibia that has been observing the TeV sky during the last decade and has accumulated 3000 hours of high-quality data in a Galactic plane survey covering the region l = 250 to 65 deg in longitude and |b| < 3.5 deg in latitude. A population of over 60 sources was discovered with pulsar wind nebulae and supernova remnants being the largest...

91. TeV and GeV emitting supernova remnants: radio observations

TeV and GeV gamma-ray emissions from supernova remnants have been recently discovered using high energy instruments, including Cerenkov air shower experiments such as H.E.S.S. and Veritas, and space missions, primarily Fermi. The origin of the GeV and TeV emission in most SNRs is not known yet- it could be high energy electrons or high energy protons. In either case, TeV and GeV supernova...

93. Dark matter Bremsstrahlung gamma ray signatures

We quantify the importance of the bremsstrahlung emission on the interstellar gas in computing indirect signatures of Dark Matter annihilation in the Galaxy, showing that it is the dominant component of the gamma-ray spectrum for some cases. We also find that, in regions in which bremsstrahlung dominates energy losses, the related γ-ray emission is only moderately sensitive to possible large...

92. Pulsar-wind Nebulae as a Dominant Population of Galactic VHE Sources

During the past decade TeV gamma-ray observatories have revealed a large number of very-high energy (VHE) sources. We will review the TeV and X-ray properties of the population of Galactic VHE sources focusing on pulsar wind-nebulae associations and unidentified TeV sources. Pulsar-wind nebulae (PWNe), shell-type supernova remnants (SNRs), and microquasar-type high-mass X-ray binaries (HMXBs)...
