Environment-based selection effects of Planck clusters
Ralf Kosyra, Daniel Gruen, Stella Seitz +5
We investigate whether the large scale structure environment of galaxy clusters imprints a selection bias on Sunyaev Zel'dovich (SZ) catalogs. Such a selection effect might be caus…
The 64 Mpixel wide field imager for the Wendelstein 2m Telescope: Design and Calibration
Ralf Kosyra, Claus Goessl, Ulrich Hopp +4
The Wendelstein Observatory of Ludwig Maximilians University of Munich has recently been upgraded with a modern 2m robotic telescope. One Nasmyth port of the telescope has been equ…
Weak lensing analysis of SZ-selected clusters of galaxies from the SPT and Planck surveys
D. Gruen, S. Seitz, F. Brimioulle +8
We present the weak lensing analysis of the Wide-Field Imager SZ Cluster of galaxy (WISCy) sample, a set of 12 clusters of galaxies selected for their Sunyaev-Zel'dovich (SZ) effec…
MAGIC Observations of PG 1553+113 during a Multiwavelength Campaign in July 2006
MAGIC Collaboration, Albert
The active galactic nucleus PG 1553+113 was observed by the MAGIC telescope in July 2006 during a multiwavelength campaign, in which telescopes in the optical, X-ray, and very high…
MAGIC observations of the unidentified TeV gamma-ray source TeV J2032+4130
J. Albert
We observed the first known very high energy (VHE) gamma-ray emitting unidentified source, TeV J2032+4130, for 94 hours with the MAGIC telescope. The source was detected with a sig…
Simultaneous multiwavelength observations of the blazar 1ES1959+650 at a low TeV flux
G. Tagliaferri, L. Foschini, G. Ghisellini +7
We present the results from a multiwavelength campaign on the TeV blazar 1ES 1959+650, performed in May, 2006. Data from the optical, UV, soft- and hard-X-ray and very high energy…
