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

Blazars are a class of active galactic nuclei (AGNs) characterized by high flux variability at
all wavelengths and compact (milliarcsecond scale) radio emission of extreme brightness
temperatures, often exceeding the Compton limit (Urry 1999). Their radio spectra are
generally well described by a power-law shape, with a “flat” spectral index α< 0. 5 (where
the flux density Fν∝ ν− α). Multi-epoch Very Long Baseline Interferometry (VLBI)
observations often show superluminal expansion, and the radio and optical emission is …

Multi-Wavelength Observations of Blazar AO 0235+ 164 in the 2008-2009 Flaring State

Abstract 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 continuous coverage by Fermi, contemporaneous observations were carried
out from the radio to γ-ray bands between 2008 September and 2009 February. In this
paper, we summarize the rich multi-wavelength data collected during the campaign
(including F-GAMMA, GASP-WEBT, Kanata, OVRO, RXTE, SMARTS, Swift, and other …
