Detectability of Gravitational Waves from Core-Collapse Supernovae for the Einstein Telescope — Markus Bachlechner, Thilo Birkenfeld, •Timo Butz, and Achim Stahl — III. Physikalisches Institut B, RWTH Aachen

Core-collapse supernovae are interesting source candidates for gravitational wave detectors. Measurements of gravitational waves from such events can provide information on the physical processes occurring during the core-collapse of massive stars, especially with multi-messenger detections. The proposed Einstein Telescope, as the first of the third generation of gravitational wave detectors, is predicted to be an order of magnitude more sensitive in the whole frequency band compared to the previous generation. Therefore, an increased event rate due to the enlarged observable volume and the ability to study details of the underlying mechanism are expected.

This talk presents an analysis of the capability to detect core-collapse supernovae with the Einstein Telescope and prospects to extract information on the progenitor star.
