Determining the core-collapse supernova explosion mechanism with current and future gravitational-wave observatories
Jade Powell, Alberto Iess, Miquel Llorens-Monteagudo +5
Gravitational waves are emitted from deep within a core-collapse supernova, which may enable us to determine the mechanism of the explosion from a gravitational-wave detection. Pre…
Assessment of a new sub-grid model for magnetohydrodynamical turbulence. II. Kelvin-Helmholtz instability
Miquel Miravet-Tenés, Pablo Cerdá-Durán, Martin Obergaulinger +1
The modelling of astrophysical systems such as binary neutron star mergers or the formation of magnetars from the collapse of massive stars involves the numerical evolution of magn…
An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the Third Observing Run of Advanced LIGO and Advanced Virgo
Marek J. Szczepańczyk, Yanyan Zheng, Javier M. Antelis +35
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed optically within 30 Mpc during the third observing run of A…
Nucleosynthesis in jet-driven and jet-associated supernovae
M. Obergaulinger, M. Reichert
In contrast to regular core-collapse supernovae, explosions of rapidly rotating massive stars can develop jets, fast collimated outflows directed along the rotational axis. Dependi…
Time integration for neutrino radiation transport using minimally implicit Runge-Kutta methods
Samuel Santos-Pérez, Martin Obergaulinger, Isabel Cordero-Carrión
The evolution of many astrophysical systems is dominated by the interaction between matter and radiation such as photons or neutrinos. The dynamics can be described by the evolutio…
Inference of proto-neutron star properties in core-collapse supernovae from a gravitational-wave detector network
T. Bruel, M-A. Bizouard, M. Obergaulinger +6
The next Galactic core-collapse supernova (CCSN) will be a unique opportunity to study within a fully multi-messenger approach the explosion mechanism responsible for the formation…
