We performed a detailed analysis of the detectability of a wide range of
gravitational waves derived from core-collapse supernova simulations using
gravitational-wave detector noise scaled to the sensitivity of the upcoming
fourth and fifth observing runs of the Advanced LIGO, Advanced Virgo, and
KAGRA. We use the coherent WaveBurst algorithm, which was used in the previous
observing runs to search for gravitational waves from core-collapse supernovae.
As coherent WaveBurst makes minimal assumptions on the morphology of a
gravitational-wave signal, it can play an important role in the first detection
of gravitational waves from an event in the Milky Way. We predict that signals
from neutrino-driven explosions could be detected up to an average distance of
10 kpc, and distances of over 100 kpc can be reached for explosions of rapidly
rotating progenitor stars. An estimated minimum signal-to-noise ratio of 10-25
is needed for the signals to be detected. We quantify the accuracy of the
waveforms reconstructed with coherent WaveBurst and we determine that the most
challenging signals to reconstruct are those produced in long-duration
neutrino-driven explosions and models that form black holes a few seconds after
the core bounce.
