A hadronic minute-scale GeV flare from quasar 3C 279?
M. Petropoulou, K. Nalewajko, M. Hayashida +1
The flat spectrum radio quasar 3C 279 is a known -ray variable source that has recently exhibited minute-scale variability at energies MeV. One-zone leptonic models for b…
Systematic Study of Gamma-ray bright Blazars with Optical Polarization and Gamma-ray Variability
Ryosuke Itoh, Krzysztof Nalewajko, Yasushi Fukazawa +18
Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence f…
First NuSTAR observations of the BL Lac - type blazar PKS~2155-304: constraints on the jet content and distribution of radiating particles
G. M. Madejski, K. Nalewajko, K. K. Madsen +35
We report the first hard X-ray observations with NuSTAR of the BL Lac type blazar PKS 2155-304, augmented with soft X-ray data from XMM-Newton and gamma-ray data from the Fermi Lar…
Applying Relativistic Reconnection to Blazar Jets
Krzysztof Nalewajko
Rapid and luminous flares of non-thermal radiation observed in blazars require an efficient mechanism of energy dissipation and particle acceleration in relativistic active galacti…
Minute-Timescale >100 MeV gamma-ray variability during the giant outburst of quasar 3C 279 observed by Fermi-LAT in 2015 June
LAT Collaboration
On 2015 June 16, Fermi-LAT observed a giant outburst from the flat spectrum radio quasar 3C 279 with a peak MeV flux of $\sim3.6\times10^{-5}\;{\rm photons}\;{\rm cm}^{-2}\;…
Kinetic study of radiation-reaction-limited particle acceleration during the relaxation of unstable force-free equilibria
Yajie Yuan, Krzysztof Nalewajko, Jonathan Zrake +2
Many powerful and variable gamma-ray sources, including pulsar wind nebulae, active galactic nuclei and gamma-ray bursts, seem capable of accelerating particles to gamma-ray emitti…
