# Detection Prospects of Core-Collapse Supernovae with Supernova-Optimized Third-Generation Gravitational-wave Detectors

## TL;DR

This paper optimizes third-generation gravitational-wave detectors for core-collapse supernova detection, finding that even with improvements, detection within our galaxy remains most feasible, with low event rates.

## Contribution

The study provides a detailed optimization of third-generation detectors specifically for core-collapse supernovae and explores technological beyond-third-generation enhancements.

## Key findings

- Detection range limited to our galaxy for current designs.
- Strain sensitivity of 3×10⁻²⁷ Hz⁻¹/² needed for one event per year.
- Beyond-third-generation improvements increase detection probability to one in twenty years.

## Abstract

We optimize the third-generation gravitational-wave detector to maximize the range to detect core-collapse supernovae. Based on three-dimensional simulations for core-collapse and the corresponding gravitational-wave waveform emitted, the corresponding detection range for these waveforms is limited to within our galaxy even in the era of third-generation detectors. The corresponding event rate is two per century. We find from the waveforms that to detect core-collapse supernovae with an event rate of one per year, the gravitational-wave detectors need a strain sensitivity of 3$\times10^{-27}~$Hz$^{-1/2}$ in a frequency range from 100~Hz to 1500~Hz. We also explore detector configurations technologically beyond the scope of third-generation detectors. We find with these improvements, the event rate for gravitational-wave observations from CCSN is still low, but is improved to one in twenty years.
