Pinpointing the TeV gamma-ray emission region in M87 using TeV and 43 GHz radio monitoring
R. M. Wagner, M. Beilicke, F. Davies +8
The TeV radio galaxy M87 is the first radio galaxy detected in the TeV regime. The structure of its jet, which is not pointing towards our line of sight, is spatially resolved in X…
A search for VHE counterparts of Galactic Fermi bright sources and MeV to TeV spectral characterization
P. H. Thomas Tam, Stefan Wagner, Omar Tibolla +1
Very high-energy (VHE; E>100 GeV) gamma-rays have been detected from a wide range of astronomical objects, such as pulsar wind nebulae (PWNe), supernova remnants (SNRs), giant mole…
Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
LAT Collaboration, E. Angelakis, C. Bailyn +39
Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…
Constraints on cosmological parameters from the EBL attenuation of VHE spectra of extragalactic sources
Bagmeet Behera, Stefan J. Wagner
The Extragalactic Background Light (EBL) causes attenuation of the VHE spectra of extragalactic sources, via pair-production. The amount of attenuation depends on the distance of t…
Correlation between the synchrotron and the inverse-Compton components, in the longterm light curve of GeV blazars
Bagmeet Behera, Marcus Hauser, Stefan J. Wagner
To explore the correlation in the GeV band (i.e. the inverse-Compton component) with the optical band (i.e. the synchrotron component) of blazars that are bright in high energies,…
A new strategy to select candidate blazars for VHE observation
Bagmeet Behera, Stefan J. Wagner
A new strategy to select candidate blazars for VHE observations, that gives an inherently complete sample from an all-sky compilation (excluding a narrow region around the galactic…
