On the phenomenological classification of continuum radio spectra variability patterns of Fermi blazars
E. Angelakis, L. Fuhrmann, I. Nestoras +9
The F-GAMMA program is a coordinated effort to investigate the physics of Active Galactic Nuclei (AGNs) via multi-frequency monitoring of {\em Fermi} blazars. The current study is…
MAGIC and Multi-Wavelength Observations of three HBLs in 2008
S. Rügamer, E. Angelakis, D. Bastieri +9
The high-frequency peaked blazars and known TeV emitters 1ES 1011+496, Mrk 180 and 1ES 2344+514 have been observed in the course of multi-wavelength campaigns in 2008, covering the…
The July 2010 outburst of the NLS1 PMN J0948+0022
L. Foschini, G. Ghisellini, L. Maraschi +23
We report about the multiwavelength campaign on the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z = 0.5846) performed in 2010 July-September and triggered by high activity…
Structural variability of 3C 111 on parsec scales
C. Großberger, M. Kadler, J. Wilms +15
We discuss the parsec-scale structural variability of the extragalactic jet 3C 111 related to a major radio flux density outburst in 2007. The data analyzed were taken within the s…
MAGIC and Multi-Wavelength Observations of Mrk 180 and 1ES 2344+514 in 2008
S. Rügamer, E. Angelakis, D. Bastieri +14
Simultaneous multi-wavelength (MW) campaigns are the most promising approaches to investigate the still unrevealed nature of blazars, active galactic nuclei which are variable on a…
The Cosmic Background Imager 2
Angela C. Taylor, Michael E. Jones, James R. Allison +14
We describe an upgrade to the Cosmic Background Imager instrument to increase its surface brightness sensitivity at small angular scales. The upgrade consisted of replacing the thi…
