Status of the VERITAS Observatory
J. Holder, V. A. Acciari, E. Aliu +79
VERITAS, an Imaging Atmospheric Cherenkov Telescope (IACT) system for gammma-ray astronomy in the GeV-TeV range, has recently completed its first season of observations with a full…
VERITAS Observations of the gamma-Ray Binary LS I +61 303
V. A. Acciari, M. Beilicke, G. Blaylock +74
LS I +61 303 is one of only a few high-mass X-ray binaries currently detected at high significance in very high energy gamma-rays. The system was observed over several orbital cycl…
Observation of gamma-ray emission from the galaxy M87 above 250 GeV with VERITAS
V. A. Acciari, M. Beilicke, G. Blaylock +74
The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in Active Galactic Nuclei from radio waves to Te…
X-ray Observations of the Boundary Layer in Dwarf Novae at Low Accretion Rates
Dirk Pandel, France A. Cordova, Keith O. Mason +1
We present a spectral analysis of XMM-Newton data of ten dwarf novae, nine of which were observed during a quiescent state. The X-ray spectra indicate the presence of a hot, optica…
Irregular Mass Transfer in the Polars VV Puppis and V393 Pavonis during the Low State
Dirk Pandel, France A. Cordova
The polars VV Pup and V393 Pav were observed with XMM-Newton during states of low accretion rate with peak X-ray luminosities of ~1 x 10^30 and ~1 x 10^31 erg/s, respectively. In b…
X-ray and UV observations of the dwarf nova VW Hyi in quiescence
Dirk Pandel, France A. Cordova, Steve B. Howell
We present an analysis of X-ray and ultra-violet data of the dwarf nova VW Hyi that were obtained with XMM-Newton during the quiescent state. The X-ray spectrum indicates the prese…
