Long-term optical monitoring of TeV emitting Blazars
K. Nilsson, E. Lindfors, L. O. Takalo +17
We present 10 years of R-band monitoring data of 31 northern blazars which were either detected at very high energy (VHE) gamma rays or listed as potential VHE gamma-ray emitters.…
Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy gamma-rays
MAGIC Collaboration, J. Aleksić, S. Ansoldi +157
The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) gamma-ray emitter by MAGIC, is one of the few non-blazar AGN detected in the VHE regime. In ord…
New distances of unresolved dwarf elliptical galaxies in the vicinity of the Local Group
Rami Rekola, Helmut Jerjen, Chris Flynn
We present Surface Brightness Fluctuation distances of nine early-type dwarf galaxies and the S0 galaxy NGC 4150 in the Local Volume based on deep B- and R-band CCD images obtained…
Optical and radio variability of the BL Lac object AO 0235+16: a possible 5-6 year periodicity
C. M. Raiteri, M. Villata, H. D. Aller +33
New optical and radio data on the BL Lacertae object AO 0235+16 have been collected in the last four years by a wide international collaboration, which confirm the intense activity…
Day-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands
R. C. Hartman, M. Villata, T. J. Balonek +36
Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and gamma rays (CGRO/EGRET) for 1999 Jan-Feb and 2000 Jan-Mar. During both of those epochs the gamma-ra…
