We report on the search for gamma ray bursts (GRBs) in energy range 1–100 GeV coincidence with prompt emission detected by satellites using Astrophysical Radiation Ground-based Observatory at YangBaJing (ARGO-YBJ) air shower detector. Thanks to its mountain location (Yangbajing, Tibet, People's Republic of China, 4300 m above sea level), active surface (∼6700 m2 Resistive Plate Chambers), and large field view (∼2 sr, limited only atmospheric absorption), ARGO-YBJ detector is particularly...
We present relativistic, radiation magnetohydrodynamic simulations of supercritical neutron star accretion columns in Cartesian geometry, including temperature-dependent, polarization-averaged Rosseland mean opacities accounting for classical electron scattering a magnetic field. Just as our previous pure Thomson simulations, vertical oscillations the shock and horizontally propagating entropy waves (photon bubbles) are all simulations. However, at high fields $\gtrsim10^{12}$~G, produce...
