Computational astrophysics

Computational astrophysics is the study of the phenomena that occur in space using computer simulations. This can involve modelling processes that take place over millions of years, such as colliding galaxies or the slow destruction of a star by a black hole. This also includes understanding the high-energy phenomena that take place in stars.

    Simulations of early galaxy formation suggest that the dynamics of structure formation, rather than the Lyman–Werner flux, drives the formation of massive black holes in the early Universe.

    A state-of-the-art magnetohydrodynamic simulation of a solar flare from emergence to eruption is able to reproduce observations at visible, UV and X-ray wavelengths, and suggests that non-thermal particles at high energy may play a less prominent role than usually assumed in flare models.

    A model of optical polarization provides a framework for studying the composition and dynamical evolution of the ejecta from the kilonova explosion accompanying the gravitational-wave event GW 170817, as well as future kilonovae.

    Blue supergiant stars (BSGs) can undergo core collapse, resulting in a type II supernova explosion. Here, Tobias Fischer et al. identify a novel phase transition from nuclear matter to a quark–gluon plasma for particularly massive BSGs (>50 M) that explains their explosion.
