The Simultaneous Low State Spectral Energy Distribution of 1ES 2344+514 from Radio to Very High Energies

MAGIC Collaboration, J. Aleksić, L. A. Antonelli +191

[Abridged] Context. To construct and interpret the spectral energy distribution (SED) of BL Lacertae objects, simultaneous broad-band observations are mandatory. Aims. We present t…

Radio and gamma-ray follow-up of the exceptionally high activity state of PKS 1510-089 in 2011

M. Orienti, S. Koyama, F. D'Ammando +24

We investigate the radio and gamma-ray variability of the flat spectrum radio quasar PKS 1510-089 in the time range between 2010 November and 2012 January. In this period the sourc…

Radio-to-gamma-ray Monitoring of the Narrow-Line Seyfert 1 Galaxy PMN J0948+0022 from 2008 to 2011

L. Foschini, E. Angelakis, L. Fuhrmann +39

We present more than three years of observations at different frequencies, from radio to high-energy gamma-rays, of the Narrow-Line Seyfert 1 (NLS1) Galaxy PMN J0948+0022 (z=0.585)…

Multi-wavelength observations of blazar AO 0235+164 in the 2008-2009 flaring state

M. Ackermann, M. Ajello, J. Ballet +208

The blazar AO 0235+164 (z = 0.94) has been one of the most active objects observed by Fermi Large Area Telescope (LAT) since its launch in Summer 2008. In addition to the continuou…

APEX sub-mm monitoring of gamma-ray blazars

S. Larsson, L. Fuhrmann, A. Weiss +13

So far, no systematic long-term blazar monitoring programs and detailed variability studies exist at sub-mm wavelengths. Here, we present a new sub-mm blazar monitoring program usi…

Unification and physical interpretation of the radio spectra variability patterns in Fermi blazars and jet emission from NLSy1s

E. Angelakis, L. Fuhrmann, I. Nestoras +10

The F-GAMMA program is among the most comprehensive programs that aim at understanding the physics in active galactic nuclei through the multi-frequency monitoring of Fermi blazars…
