Ordered magnetic fields around the 3C 84 central black hole
G. F. Paraschos, J. -Y. Kim, M. Wielgus +279
3C84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region nec…
Broadband Multi-wavelength Properties of M87 during the 2018 EHT Campaign including a Very High Energy Flaring Episode
J. C. Algaba, M. Balokovic, S. Chandra +738
The nearby elliptical galaxy M87 contains one of the only two supermassive black holes whose emission surrounding the event horizon has been imaged by the Event Horizon Telescope (…
Particle Acceleration via Transient Stagnation Surfaces in MADs During Flux Eruptions
V. Mpisketzis, G. F. Paraschos, H. Ho-Yin Ng +1
In this study, we focus on the simulation of accretion processes in Magnetically Arrested Disks (MADs) and investigate the dynamics of plasma during flux eruption events. We employ…
Flares from plasmoids and current sheets around Sgr A*
I. Dimitropoulos, A. Nathanail, M. Petropoulou +2
The supermassive black hole Sgr A* at the center of our galaxy produces repeating near-infrared flares that are observed by ground and space based instruments. This activity has be…
Using evolutionary algorithms to model relativistic jets: Application to NGC 1052
C. M. Fromm, Z. Younsi, A. Bazcko +9
High-resolution Very-Long-Baseline Interferometry observations of NGC 1052 show a two sided jet with several regions of enhanced emission and a clear emission gap between the two j…
Secondary black hole-induced magnetic reconnection in OJ 287: Implications for X-ray and radio emission
S. Boula, A. Nathanail
OJ 287, a nearby blazar, has exhibited remarkable variability in its optical light curve since 1888, characterized by ~12-year quasi-periodic outbursts. These events are attributed…
Disk mass after a binary neutron star merger as a constraining parameter for short Gamma Ray Bursts
V. Mpisketzis, A. Nathanail
Context. The coincident detection of GW170817 and GRB170817A marked a milestone for the connection between binary neutron star (BNS) mergers and short gamma-ray bursts (sGRBs). The…
