The violent hard X-ray variability of Mrk 421 observed by NuSTAR in 2013 April
(American Astronomical Society, 2015)
The well-studied blazar Markarian 421 (Mrk 421, z = 0.031) was the subject of an intensive multi-wavelength campaign when it flared in 2013 April. The recorded X-ray and very high-energy (E > 100 GeV) γ-ray fluxes are the ...
Particle diffusion and localized acceleration in inhomogeneous AGN jets. I. Steady-state spectra
(Oxford University Press, 2015)
We study the acceleration, transport, and emission of particles in relativistic jets. Localized stochastic particle acceleration, spatial diffusion, and synchrotron as well as synchrotron self-Compton (SSC) emission are ...
Hadronic models of blazars require a change of the accretion paradigm
(Oxford University Press, 2015)
We study hadronic models of broad-band emission of jets in radio-loud active galactic nuclei, and their implications for the accretion in those sources. We show that the models that account for broad-band spectra of blazars ...
Magnetic field amplification and flat spectrum radio quasars
(Oxford University Press, 2014)
We perform time-dependent, spatially resolved simulations of blazar emission to evaluate
several flaring scenarios related to magnetic-field amplification and enhanced particle acceleration.
The code explicitly accounts ...
