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…
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…
VLBA observations of a rare multiple quasar imaging event caused by refraction in the interstellar medium
A. B. Pushkarev, Y. Y. Kovalev, M. L. Lister +9
We report on the first detection of the theoretically-predicted rare phenomenon of multiple parsec-scale imaging of an active galactic nucleus induced by refractive effects due to…
The Luminosity Function of Fermi-detected Flat-Spectrum Radio Quasars
M. Ajello, M. S. Shaw, R. W. Romani +8
Fermi has provided the largest sample of γ-ray selected blazars to date. In this work we use a complete sample of FSRQs detected during the first year of operation to determine the…
The radio/gamma-ray connection in Active Galactic Nuclei in the era of the Fermi Large Area Telescope
M. Ackermann, M. Ajello, A. Allafort +144
We present a detailed statistical analysis of the correlation between radio and gamma-ray emission of the Active Galactic Nuclei (AGN) detected by Fermi during its first year of op…
Simultaneous Planck, Swift, and Fermi observations of X-ray and gamma-ray selected blazars
P. Giommi, G. Polenta, A. Lahteenmaki +92
We present simultaneous Planck, Swift, Fermi, and ground-based data for 105 blazars belonging to three samples with flux limits in the soft X-ray, hard X-ray, and gamma-ray bands.…
