Observing Supernova Neutrino Light Curves with Super-Kamiokande. V. Distance Estimation with Neutrinos Alone
arxiv(2024)
摘要
Neutrinos are pivotal signals in multi-messenger observations of supernovae.
Recent advancements in the analysis method of supernova neutrinos, especially
in quantitative analysis, have significantly broadened scientific
possibilities. This study demonstrates the feasibility of estimating distances
to supernovae using quantitative analysis techniques for supernova neutrinos.
This estimation utilizes the direct relationship between the radius of a
neutron star and the distance to the supernova. The radius of a neutron star is
determined with an approximate uncertainty of 10
X-rays and gravitational waves. By integrating this information, the distance
to the supernova can be estimated with an uncertainty of within 15
confidence level. It has been established that neutrinos can pinpoint the
direction of supernovae, and when combined with distance estimates,
three-dimensional localization becomes achievable. This capability is vital for
follow-up observations using multi-messenger approaches. Moreover, more precise
distance determinations to supernovae through follow-up observations, such as
optical observations, allow for accurate measurements of neutron star radii.
This data, via the neutron star mass-radius relationship, could provide various
insights into nuclear physics.
