Model analysis of the very high energy detections of the starburst galaxies M82 and NGC 253
E. de Cea del Pozo, D. F. Torres, A. Y. Rodriguez +1
In the light of recent results detecting the nearest starburst galaxies M 82 and NGC 253 at very high energy (VHE), we present a multi-wavelength model succesfully explaining their…
Fermi observations of Cassiopeia and Cepheus: diffuse gamma-ray emission in the outer Galaxy
LAT collaboration
We present the analysis of the interstellar gamma-ray emission measured by the Fermi Large Area Telescope toward a region in the second Galactic quadrant at 100 deg < l < 145 deg a…
Detection of Gamma-Ray Emission from the Starburst Galaxies M82 and NGC 253 with the Large Area Telescope on Fermi
Fermi LAT Collaboration, A. A. Abdo
We report the detection of high-energy gamma-ray emission from two starburst galaxies using data obtained with the Large Area Telescope on board the Fermi Gamma-ray Space Telescope…
Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN
LAT Collaboration, G. Ghisellini, L. Maraschi +1
We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z…
Fermi Large Area Telescope Observations of the Crab Pulsar and Nebula
The Fermi LAT collaboration, the Fermi Pulsar Timing Consortium, : +1
We report on gamma-ray observations of the Crab Pulsar and Nebula using 8 months of survey data with the Fermi Large Area Telescope (LAT). The high quality light curve obtained usi…
Fermi LAT Observations of LS 5039
The Fermi LAT collaboration
The first results from observations of the high mass X-ray binary LS 5039 using the Fermi Gamma-ray Space Telescope data between 2008 August and 2009 June are presented. Our result…
Simultaneous Multiwavelength observation of Mkn 501 in a low state in 2006
The MAGIC Collaboration, H. Anderhub, R. Sato +4
We present results of the multiwavelength campaign on the TeV blazar Mkn 501 performed in 2006 July, including MAGIC for the VHE gamma-ray band and Suzaku for the X-ray band. A VHE…
Fermi-LAT Discovery of Extended Gamma-ray Emission in the Direction of Supernova Remnant W51C
Fermi LAT collaboration
The discovery of bright gamma-ray emission coincident with supernova remnant (SNR) W51C is reported using the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescop…
The First Fermi Large Area Telescope Catalog of Gamma-ray Pulsars
A. A. Abdo
The dramatic increase in the number of known gamma-ray pulsars since the launch of the Fermi Gamma-ray Space Telescope (formerly GLAST) offers the first opportunity to study a popu…
Fermi LAT Observation of Diffuse Gamma-Rays Produced Through Interactions between Local Interstellar Matter and High Energy Cosmic Rays
A. A. Abdo
Observations by the Large Area Telescope (LAT) on the \textit{Fermi} mission of diffuse -rays in a mid-latitude region in the third quadrant (Galactic longitude from $200\ar…

Simultaneous Multiwavelength Observations of Markarian 421 During Outburst
The VERITAS Collaboration, I. de la Calle Perez, A. Ibarra +2
We report on the results of two coordinated multiwavelength campaigns that focused on the blazar Markarian 421 during its 2006 and 2008 outbursts. These campaigns obtained UV and X…
Microquasar observations with the MAGIC telescope
T. Y. Saito, R. Zanin, P. Bordas +7
Microquasars, X-ray binaries displaying relativistic jets driven by accretion onto a compact object, are some of the most efficient accelerators in the Galaxy. Theoretical models p…

First bounds on the VHE gamma-ray emission from isolated Wolf-Rayet binary systems
Diego F. Torres, Javier Rico, Vincenzo Vitale
Different theoretical models predict VHE gamma-ray emission to arise in tight binary star systems (high mass-loss and high wind speeds), which has not been confirmed experimentally…
