Abstract:
The next Galactic supernova is expected to bring great opportunities
for the direct detection of gravitational waves (GW), full flavour
neutrinos, and multiwavelength photons. To maximize the science return
from such a rare event, it is essential to have established classes of
possible situations and preparations for appropriate observations. To
this end, we use a long-term numerical simulation of the core-collapse
supernova (CCSN) of a 17M☉ red supergiant progenitor to
self-consistently model the multimessenger signals expected in GW,
neutrino, and electromagnetic messengers. This supernova model takes
into account the formation and evolution of a protoneutron star,
neutrino-matter interaction, and neutrino transport, all within a
two-dimensional shock hydrodynamics simulation. With this, we
separately discuss three situations: (i) a CCSN at the Galactic
Center, (ii) an extremely nearby CCSN within hundreds of parsecs, and
(iii) a CCSN in nearby galaxies within several Mpc. These distance
regimes necessitate different strategies for synergistic observations.
In a Galactic CCSN, neutrinos provide strategic timing and pointing
information. We explore how these in turn deliver an improvement in
the sensitivity of GW analyses and help to guarantee observations of
early electromagnetic signals. To facilitate the detection of
multimessenger signals of CCSNe in extremely nearby and extragalactic
distances, we compile a list of nearby red supergiant candidates and a
list of nearby galaxies with their expected CCSN rates. By exploring
the sequential multimessenger signals of a nearby CCSN, we discuss
preparations for maximizing successful studies of such an
unprecedented stirring event.
Description:
In Table 2, we compiled a list of nearby RSGs from the literature.
RSGs associated with OB associations and other RSGs. Our final RSG
list consists of 212 RSG candidates.
To estimate the CCSN rate of each galaxy, we adopt a subset of the
Karachentsev catalogue for which the star formation rate can be
observationally estimated. The resulting CCSN rates are summarized in
the final column of Table 3.
