A Search for Pulsations from Geminga Above 100 GeV with VERITAS
E. Aliu, S. Archambault, A. Archer +81
We present the results of 71.6 hours of observations of the Geminga pulsar (PSR J0633+1746) with the VERITAS very-high-energy gamma-ray telescope array. Data taken with VERITAS bet…
Investigating Broadband Variability of the TeV Blazar 1ES 1959+650
E. Aliu, S. Archambault, T. Arlen +92
We summarize broadband observations of the TeV-emitting blazar 1ES 1959+650, including optical R-band observations by the robotic telescopes Super-LOTIS and iTelescope, UV observat…
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).…
Very-high energy observations of the Galactic center region by VERITAS in 2010-2012
The VERITAS Collaboration
The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) gamma-ray observations. Potential sources of GeV/TeV gamma-ray emissio…
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…
