Global alignments of parsec-scale AGN radio jets and their polarization planes
D. Blinov, C. Casadio, N. Mandarakas +1
A number of works reported on the existence of a large scale alignment of the polarization plane of extragalactic sources as well as the alignment of radio-sources structural axes.…
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…
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…
The radio/gamma-ray connection in Active Galactic Nuclei in the era of the Fermi Large Area Telescope
M. Ackermann, M. Ajello, A. Allafort +144
We present a detailed statistical analysis of the correlation between radio and gamma-ray emission of the Active Galactic Nuclei (AGN) detected by Fermi during its first year of op…
Simultaneous Planck, Swift, and Fermi observations of X-ray and gamma-ray selected blazars
P. Giommi, G. Polenta, A. Lahteenmaki +92
We present simultaneous Planck, Swift, Fermi, and ground-based data for 105 blazars belonging to three samples with flux limits in the soft X-ray, hard X-ray, and gamma-ray bands.…
The broadband emission properties of AGN jets
C. S. Chang, E. Ros, M. Kadler +7
The origin of the high-energy emission of blazars is still a matter of debate. To investigate the emission mechanism of extragalactic outflows and to pin down the location of the e…
