GeV photon absorption in cosmologically evolving quasar environments
A. Reimer
The question of a possible redshift-dependence of gamma-ray absorption due to gamma-gamma pair production of jet photons in the accretion disk and BLR radiation field in strong-lin…
Non-thermal high-energy emission from colliding winds of massive stars
A. Reimer, M. Pohl, O. Reimer
Colliding winds of massive star binary systems are considered as potential sites of non-thermal high-energy photon production. This is motivated merely by the detection of synchrot…
News from a Multi-Wavelength Monitoring Campaign on Mrk 421
Wei Cui
We conducted a daily monitoring campaign on Mrk 421 in 2003 and 2004 with the Whipple 10 m telescope and the large-area instruments aboard RXTE, simultaneously covering TeV and X-r…
Calibration of cameras of the H.E.S.S. detector
H. E. S. S. Collaboration, :, F. Aharonian
H.E.S.S. - the High Energy Stereoscopic System- is a new system of large atmospheric Cherenkov telescopes for GeV/TeV astronomy. Each of the four telescopes of 107 m^2 mirror area…
M87 as a misaligned Synchrotron-Proton Blazar
A. Reimer, R. J. Protheroe, A. -C. Donea
The giant radio galaxy M87 is usually classified as a Fanaroff-Riley class I source, suggesting that M87 is a mis-aligned BL Lac object. Its unresolved nuclear region emits strong…
