DOI: 10.1093/mnras/stab116
Abstract: We present 3D hydrodynamic simulations of neutrino-driven supernovae (SNe) with the PROMETHEUS-HOTB code, evolving the asymmetrically expanding ejecta from shock breakout until they reach the homologous expansion phase after roughly one year. Our calculations continue… read more here.

DOI: 10.1093/mnras/stx534
Abstract: We study the morphologies of core collapse supernova remnants (CCSNRs) and find that about third of CCSNRs in our sample have two opposite `ears' protruding from their main shell. We assume that the ears are… read more here.

DOI: 10.1103/physrevd.107.103025
Abstract: We perform multi-dimensional core-collapse supernova (CCSN) simulations in a massive scalar-tensor theory for the first time with a realistic equation of state and multi-energy neutrino radiation. Among the set of our models varying the scalar… read more here.

DOI: 10.1103/physrevd.96.123013
Abstract: A detection of a core-collapse supernova signal with an advanced LIGO and Virgo gravitational-wave detector network will allow us to measure astrophysical parameters of the source. In real advanced gravitational-wave detector data, there are transient… read more here.

DOI: 10.1103/physrevlett.130.211401
Abstract: One of the greatest uncertainties in any modeling of inner engine of core-collapse supernova (CCSN) is neutrino flavor conversions driven by neutrino self-interactions. We carry out large-scale numerical simulations of multi-energy, multi-angle, three-flavor framework, and… read more here.
