Probing Shock Properties with Non-thermal X-ray Filaments in Cas A

Miguel Araya, David Lomiashvili, Chulhoon Chang +2

Thin non-thermal X-ray filaments are often seen in young supernova remnants. We used data from the 1 Ms Chandra observation of Cassiopeia A to study spectral properties of some of…

Simultaneous multi-frequency observation of the unknown redshift blazar PG 1553+113 in March-April 2008

MAGIC Collaboration, J. Aleksić, H. Anderhub +161

The blazar PG 1553+113 is a well known TeV gamma-ray emitter. In this paper, we determine its spectral energy distribution using simultaneous multi-frequency data in order to study…

Multiwavelength observations of a TeV-Flare from W Comae

VERITAS collaboration, V. A. Acciari, E. Aliu +167

We report results from an intensive multiwavelength campaign on the intermediate-frequency-peaked BL Lacertae object W Com (z=0.102) during a strong outburst of very high energy ga…

AGILE detection of a rapid gamma-ray flare from the blazar PKS 1510-089 during the GASP-WEBT monitoring

F. D'Ammando, G. Pucella, C. M. Raiteri +103

We report the detection by the AGILE satellite of a rapid gamma-ray flare from the powerful gamma-ray quasar PKS 1510-089, during a pointing centered on the Galactic Center region…

On the very high energy (>25GeV) pulsed emission in the Crab pulsar

Machabeli George, Osmanov Zaza

We have examined the recently detected very high energy (VHE) pulsed radiation from the Crab pulsar. According to the observational evidence, the observed emission (>25GeV) peaks a…

On particle acceleration and very high energy gamma-ray emission in Crab-like pulsars

Zaza Osmanov, Frank M. Rieger

The origin of very energetic charged particles and the production of very high-energy (VHE) gamma-ray emission remains still a challenging issue in modern pulsar physics. By applyi…

Multiwavelength Observations of Markarian 421 in 2005 - 2006

D. Horan, V. A. Acciari, S. M. Bradbury +71

Since September 2005, the Whipple 10m Gamma-ray Telescope has been operated primarily as a blazar monitor. The five Northern Hemisphere blazars that have already been detected at t…

The Synchrotron Emission Mechanism in the Recently Detected Very High Energy Radiation from the Crab Pulsar

Machabeli George, Osmanov Zaza

Interpretation of the recently discovered very high energy (VHE) pulsed emission from the Crab pulsar is presented. By taking into account the fact that Crab pulsar's radiation for…

Is very high energy emission from the BL Lac 1ES 0806+524 centrifugally driven?

Z. Osmanov

We investigate the role of centrifugal acceleration of electrons in producing the very high energy (VHE) radiation from the BL Lac object 1ES 0806+524, recently detected by VERITAS…
