Wind-confined jet collimation revealed by the acceleration-phase photosphere of GRB 220426A
Felix Ryde, Asaf Pe'er
We analyze the prompt emission of the exceptionally bright GRB 220426A observed by {\it Fermi}/GBM, whose time-resolved spectra are among the narrowest measured in any GRB. Here we…
Characterizing the Scale Height and Filamentary Structure of Radiatively Cooled MADs
Akshay Singh, Damien Begue, Asaf Pe'er
Radiative cooling can strongly influence the structure and dynamics of black hole accretion disks. Here, we perform general relativistic magnetohydrodynamic (GR-MHD) simulations of…
Radiation-Driven Origin of Super-Equipartition Magnetic Fields in Accretion Discs and Outflows
Mukesh Kumar Vyas, Asaf Pe'er
Magnetic fields play a central role in accretion physics around black holes, yet their physical origin within accretion flows remains an open problem. In this work, we investigate…
Impact of Spectral Coverage on Parameter recovery in Blazar Modeling
N. Sahakyan, D. Bégué, P. Giommi +2
Understanding the impact of spectral coverage on parameter recovery is critical for accurate interpretation of blazar spectra. In this study, we examine how the data coverage influ…
Direct Solution of the Time-Dependent Covariant Radiative Transfer Equation and its Coupling to General Relativistic Magnetohydrodynamics with cuHARM
John Wallace, Damien Bégué, Asaf Pe'er
In this paper we present a major update to the general relativistic magnetohydrodynamics (GRMHD) code cuHARM, which adds fully covariant treatment of radiation transport and the su…
Bridging the Gap between Collisional and Collisionless Plasma Shocks: A Simulation Study using OSIRIS
Yossef Nissim Kindi, Asaf Pe'er, Antoine Bret +2
Shock waves in plasmas can be characterized by the mechanisms behind their formation. When binary collisions are frequent, dissipation is collision-driven and the shock width is a…
