The GeV-scale gamma-ray excess observed from the region surrounding Galactic Center has been interpreted as either products of annihilating dark matter particles, or emission a large population faint and centrally-located millisecond pulsars. If pulsars are responsible for this signal, they should also produce detectable levels TeV-scale emission. In study, we employ template-based analysis sim...
X-ray binaries stand as the brightest Xray sources in the galaxy, showing both variable X-ray emission and extreme flares. Some of these systems have been recently discovered to be TeV gamma-ray emitters, with the high energy emission posited as resulting from particle acceleration in relativistic jets or from shocks between pulsar and stellar winds. VERITAS, an array of four 12m imaging atmosp...
The IceCube Neutrino Observatory is the world’s largest high energy neutrino telescope, using the Antarctic ice cap as a Cherenkov detector medium. DeepCore, the low energy extension to IceCube, is an infill array with a fiducial volume of around 30 MTon in the deepest, clearest ice, aiming for an energy threshold as low as 10 GeV and extending IceCube’s sensitivity to indirect dark matter sear...
The unidentified TeV gamma-ray source MGRO J1908+06/HESS J1908+063 was observed with the VERITAS Imaging Atmospheric Cherenkov Array during October 2007 and May-June 2008. This extended source is located on the galactic plane at a galactic longitude of 40.45 degrees and has a hard TeV spectrum with an index of Γ≈2.08 [1]. The Very High Energy (VHE) gamma-ray flux was measured by H.E.S.S. out to...
STACEE is a ground based γ-ray observatory that uses a heliostat array, built for solar energy research, to detect atmospheric Cherenkov radiation from γ-ray initiated extensive air showers. During the first half of 2001, a prototype detector, STACEE-48, was used to detect the blazar Markarian 421, which was in an extremely active state. Observations from March to May of 2001 yielded an integra...
