Multiwavelength observations of the gamma-ray emitting narrow-line Seyfert 1 PMN J0948+0022 in 2011
F. D'Ammando, J. Larsson, M. Orienti +13
We report on radio-to-gamma-ray observations during 2011 May-September of PMN J0948+0022, the first narrow-line Seyfert 1 (NLSy1) galaxy detected in gamma-rays by Fermi-LAT. Strong…
Connecting radio variability to the characteristics of gamma-ray blazars
Joseph L. Richards, Talvikki Hovatta, Walter Max-Moerbeck +3
We present results from four years of twice-weekly 15 GHz radio monitoring of about 1500 blazars with the Owens Valley Radio Observatory 40 m telescope. Using the intrinsic modulat…
MAGIC observations and multifrequency properties of the Flat Spectrum Radio Quasar 3C 279 in 2011
J. Aleksić, S. Ansoldi, L. A. Antonelli +168
We study the multifrequency emission and spectral properties of the quasar 3C 279. We observed 3C 279 in very high energy (VHE, E>100GeV) gamma rays, with the MAGIC telescopes duri…
The Cosmic Evolution of Fermi BL Lacertae Objects
M. Ajello, R. W. Romani, D. Gasparrini +14
Fermi has provided the largest sample of gamma-ray selected blazars to date. In this work we use a uniformly selected set of 211 BL Lacertae (BL Lac) objects detected by it Fermi d…
An Exceptional Radio Flare in Markarian 421
Joseph L. Richards, Talvikki Hovatta, Matthew L. Lister +9
In September 2012, the high-synchrotron-peaked (HSP) blazar Markarian 421 underwent a rapid wideband radio flare, reaching nearly twice the brightest level observed in the centimet…
Intrinsic brightness temperatures of blazar jets at 15 GHz
T. Hovatta, E. M. Leitch, D. C. Homan +5
We have developed a new Bayesian Markov Chain Monte Carlo method to deconvolve light curves of blazars into individual flares, including proper estimation of the fit errors. We use…
