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)…
VLBA monitoring of Mrk 421 at 15 GHz and 24 GHz during 2011
R. Lico, M. Giroletti, M. Orienti +13
High-resolution radio observations are ideal for constraining the value of physical parameters in the inner regions of active-galactic-nucleus jets and complement results on multiw…
Multiwavelength Intraday Variability of the BL Lac S5 0716+714
Alok C. Gupta, T. P. Krichbaum, P. J. Wiita +31
We report results from a 1 week multi-wavelength campaign to monitor the BL Lac object S5 0716+714 (on December 9-16, 2009). In the radio bands the source shows rapid (~ (0.5-1.5)…
SBS 0846+513: a new gamma-ray emitting Narrow-Line Seyfert 1 galaxy
F. D'Ammando, M. Orienti, J. Finke +11
We report Fermi-LAT observations of the radio-loud AGN SBS 0846+513 (z=0.5835), optically classified as a Narrow-Line Seyfert 1 galaxy, together with new and archival radio-to-X-ra…
