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…
Inter-Plasmoid Compton Scattering and the Compton Dominance of BL Lacs
I. M. Christie, M. Petropoulou, L. Sironi +1
Blazar emission models based on magnetic reconnection succeed in reproducing many observed spectral and temporal features, including the short-duration luminous flaring events. Pla…
The Role of Magnetic Field Geometry in the Evolution of Neutron Star Merger Accretion Discs
I. M. Christie, A. Lalakos, A. Tchekhovskoy +4
Neutron star mergers are unique laboratories of accretion, ejection, and r-process nucleosynthesis. We used 3D general relativistic magnetohydrodynamic simulations to study the rol…
Radiative Signatures of Plasmoid-Dominated Reconnection in Blazar Jets
I. M. Christie, M. Petropoulou, L. Sironi +1
The multi-wavelength spectral and temporal variability observed in blazars set tight constraints on current theoretical emission models. Here, we investigate the relativistic magne…
