Quantitative comparisons of VHE gamma-ray blazar flares with relativistic reconnection models
J. Jormanainen, T. Hovatta, I. M. Christie +3
The origin of extremely fast variability is one of the long-standing questions in the gamma-ray astronomy of blazars. While many models explain the slower, lower energy variability…
Striped Jets in Post Neutron Star Merger Systems
Emma Kaufman, I. M. Christie, A. Lalakos +2
Models invoking magnetic reconnection as the particle acceleration mechanism within relativistic jets often adopt a gradual energy dissipation profile within the jet. However, such…
Bridging Bondi and Event Horizon Scales: 3D GRMHD Simulations Reveal X-Shaped Radio Galaxy Morphology
Aretaios Lalakos, Ore Gottlieb, Nick Kaaz +6
X-shaped radio galaxies (XRGs) produce misaligned X-shaped jet pairs and make up of radio galaxies. XRGs are thought to emerge in galaxies featuring a binary superma…
Confronting observations of VHE gamma-ray blazar flares with reconnection models
J. Jormanainen, T. Hovatta, E. Lindfors +3
Several models have been suggested to explain the fast gamma-ray variability observed in blazars, but its origin is still debated. One scenario is magnetic reconnection, a process…
The observability of plasmoid-powered -ray flares with the Fermi Large Area Telescope
Manuel Meyer, Maria Petropoulou, Ian Christie
The exact mechanism for the production of fast -ray variability in blazars remains debated. Magnetic reconnection, in which plasmoids filled with relativistic particles and magn…
Inverse Compton Signatures of Gamma-Ray Burst Afterglows
Hao Zhang, Ian Christie, Maria Petropoulou +2
The afterglow emission from gamma-ray bursts (GRBs) is believed to originate from a relativistic blast wave driven into the circumburst medium. Although the afterglow emission from…
