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…

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…

Assessing the Significance of Apparent Correlations Between Radio and Gamma-ray Blazar Fluxes

V. Pavlidou, J. L. Richards, W. Max-Moerbeck +13

Whether a correlation exists between the radio and gamma-ray flux densities of blazars is a long-standing question, and one that is difficult to answer confidently because of vario…
