Calibrating the power of relativistic jets
L. Foschini, M. L. Lister, T. Hovatta +12
There are several methods to calculate the radiative and kinetic power of relativistic jets, but their results can differ by one or two orders of magnitude. Therefore, it is necess…
The relativistic jet of the -ray emitting narrow-line Seyfert 1 galaxy PKS J12220413
Daniel Kynoch, Hermine Landt, Martin J. Ward +5
We present a multi-frequency study of PKS J12220413 (4C04.42), currently the highest redshift -ray emitting narrow-line Seyfert 1 (-NLS1). We assemble a broad spectral…
Using evolutionary algorithms to model relativistic jets: Application to NGC 1052
C. M. Fromm, Z. Younsi, A. Bazcko +9
High-resolution Very-Long-Baseline Interferometry observations of NGC 1052 show a two sided jet with several regions of enhanced emission and a clear emission gap between the two j…
High-Energy Polarimetry - a new window to probe extreme physics in AGN jets
B. Rani, H. Zhang, S. D. Hunter +31
The constantly improving sensitivity of ground-based and space-borne observatories has made possible the detection of high-energy emission (X-rays and gamma-rays) from several thou…
RoboPol: A four-channel optical imaging polarimeter
A. N. Ramaprakash, C. V. Rajarshi, H. K. Das +30
We present the design and performance of RoboPol, a four-channel optical polarimeter operating at the Skinakas Observatory in Crete, Greece. RoboPol is capable of measuring both re…
F-GAMMA: Multi-frequency radio monitoring of Fermi blazars. The 2.64 to 43 GHz Effelsberg light curves from 2007-2015
E. Angelakis, L. Fuhrmann, I. Myserlis +7
The advent of the Fermi-GST with its unprecedented capability to monitor the entire 4 pi sky within less than 2-3 hours, introduced new standard in time domain gamma-ray astronomy.…
