Abstract: Type II supernovae (SNe II) originate from the explosion of hydrogen-rich supergiant massive stars. Their first electromagnetic signature is the shock breakout (SBO), a short-lived phenomenon that can last for hours to days depending on… read more here.

Abstract: We perform smoothed particle hydrodynamics (SPH) simulations to study the material ejection from a grooved tin surface under unsupported shocks with different shock breakout pressures. It is found that melting has a substantial impact on… read more here.

Abstract: The short Gamma-Ray Burst, GRB170817A, that followed the binary neutron star merger gravitational waves signal, GW170817, is not a usual sGRB. It is weaker by three orders of magnitude than the weakest sGRB seen before… read more here.
