A variability and localization study of 3EG J1746-2851
Martin Pohl
I have studied the variability properties and localization of 3EG J1746-2851 based on EGRET data of the observing periods 1-4. Using corrections for know systematic problems and pe…
The Outer Tracker Detector of the HERA-B Experiment. Part II: Front-End Electronics
H. Albrecht et al.
The HERA-B Outer Tracker is a large detector with 112674 drift chamber channels. It is exposed to a particle flux of up to 2x10^5/cm^2/s thus coping with conditions similar to thos…
A Million-Second Chandra View of Cassiopeia A
Una Hwang, J. Martin Laming, Carles Badenes +20
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW count…
Complementary constraints from FR IIb radio galaxies and X-ray gas mass fractions in clusters on non-standard cosmological models
Dirk Puetzfeld, Martin Pohl, Zong-Hong Zhu
We use recent measurements of the dimensionless coordinate distances from Fanaroff-Riley Type IIb radio galaxies and the X-ray gas mass fractions in clusters to constrain the param…
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…
