Gamma-ray signatures from pair cascades in recombination-line radiation fields
Christoph Wendel, Josefa Becerra González, Amit Shukla +2
Beams of ultra-relativistic electrons in blazar jets develop pair cascades interacting with ambient soft photons. Employing coupled kinetic equations with escape terms, we model th…
Electron-beam interaction with emission-line clouds in blazars
Christoph Wendel, Josefa Becerra González, David Paneque +1
Context: An electron-positron beam escaping from the magnetospheric vacuum gap of an accreting black hole interacts with recombination-line photons from surrounding gas clouds. Inv…
MAGIC observations of variable very-high-energy gamma-ray emission from PKS1510-089 during May 2015 outburst
Julian Sitarek, Josefa Becerra González, Vandad Fallah Ramazani Elina Lindfors +11
PKS1510-089 is a flat spectrum radio quasar located at a redshift of 0.36. It is one of only a few such sources detected in very-high-energy (VHE, >100 GeV) gamma rays. Though PKS1…
First study of Mrk 501 through the eyes of NuSTAR, VERITAS and the LIDAR-corrected eyesight of MAGIC
Koji Noda, Amy Furniss, Josefa Becerra González +2
The blazar Mrk 501 is among the brightest X-ray and TeV sources in the sky, and among the few sources whose spectral energy distributions can be characterized by current instrument…
