TDLI Meeting Room 300-1

Abstract

Core-collapse supernova marks the death of massive stars with a zero-age-main-sequence mass of 8-100 solar masses, and is one of the most important objects in modern astronomy. The ability of emitting gravitational waves, neutrinos, and electromagnetic waves makes core-collapse supernovae excellent targets for multi-messenger astronomical surveys. In this talk, I will present the consequences of a first-order QCD phase transition in core-collapse supernovae, studied with state-of-the-art two-dimensional hydrodynamic simulations. In particular, I will talk about how the detection of multi-messenger signals can probe the phase transition and provide important information on supernova physics.

Biography

I did my phD at the Chinese University of Hong Kong and I am currently a post-doc at The Oskar Klein Centre and Department of Astronomy in Stockholm University, Sweden. I majorly work on computer simulations of stellar evolution and supernovae and their multi-messenger (gravitational-wave and neutrino) signals. For more information, visit joshuashzha.github.io. Now I am visiting TDLi institute for a month and wish to talk and collaborate with TDLI researchers.
