Constraints on the Intergalactic Magnetic Field with Gamma-Ray Observations of Blazars

Justin D. Finke, Luis C. Reyes, Markos Georganopoulos +4

Distant BL Lacertae objects emit rays which interact with the extragalactic background light (EBL), creating electron-positron pairs, and reducing the flux measured by ground-b…

Investigating powerful jets in radio-loud Narrow Line Seyfert 1s

M. Orienti, F. D'Ammando, J. Larsson +5

We report results on multiband observations from radio to gamma-rays of the two radio-loud narrow-line Seyfert 1 (NLSy1) galaxies PKS 2004-447 and J1548+3511. Both sources show a c…

Fourier Analysis of Blazar Variability: Klein-Nishina Effects and the Jet Scattering Environment

Justin D. Finke, Peter A. Becker

The strong variability of blazars can be characterized by power spectral densities (PSDs) and Fourier frequency-dependent time lags. In previous work, we created a new theoretical…

From Radio to TeV: The surprising Spectral Energy Distribution of AP Librae

D. A. Sanchez, B. Giebels, P. Fortin +10

Following the discovery of high-energy (HE; ) and very-high-energy (VHE; ) -ray emission from the low-frequency-peaked BL~Lac (LBL) object AP…

Suzaku and Fermi Observations of Gamma-Ray Bright Radio Galaxies: Origin of the X-ray Emission and Broad-Band Modeling

Y. Fukazawa, S. Tokuda, R. Itoh +3

We performed a systematic X-ray study of eight nearby -ray bright radio galaxies with {\em Suzaku} for understanding the origin of their X-ray emissions. The {\em Suzaku} spectr…

Near-Equipartition Jets with Log-Parabola Electron Energy Distribution and the Blazar Spectral-Index Diagrams

Charles D. Dermer, Dahai Yan, Li Zhang +2

Fermi-LAT analyses show that the gamma-ray photon spectral indices Gamma_gamma of a large sample of blazars correlate with the vFv peak synchrotron frequency v_s according to the r…
