Particle diffusion and localized acceleration in inhomogeneous AGN jets - Part I: Steady-state spectra
Xuhui Chen, Martin Pohl, Markus Boettcher
We study the acceleration, transport, and emission of particles in relativistic jets. Localized stochastic particle acceleration, spatial diffusion, and synchrotron as well as sync…
The most powerful flaring activity from the NLSy1 PMN J0948+0022
F. D'Ammando, M. Orienti, J. Finke +73
We report on multifrequency observations performed during 2012 December-2013 August of the first narrow-line Seyfert 1 galaxy detected in gamma rays, PMN J0948+0022 ( = 0.5846).…
Investigating the TeV Morphology of MGRO J1908+06 with VERITAS
E. Aliu, S. Archambault, T. Aune +85
We report on deep observations of the extended TeV gamma-ray source MGRO J1908+06 made with the VERITAS very high energy (VHE) gamma-ray observatory. Previously, the TeV emission h…
Magnetic Field Amplification and Flat Spectrum Radio Quasars
Xuhui Chen, Ritaban Chatterjee, Haocheng Zhang +10
We perform time-dependent, spatially-resolved simulations of blazar emission to evaluate several flaring scenarios related to magnetic-field amplification and enhanced particle acc…
Synchrotron Polarization in Blazars
Haocheng Zhang, Xuhui Chen, Markus Boettcher
We present a detailed analysis of time- and energy-dependent synchrotron polarization signatures in a shock-in-jet model for gamma-ray blazars. Our calculations employ a full 3D ra…
