Compact stars as probes of nuclear and particle physics in light of multi-messenger astronomy
by Seminar Hall 31, 2nd Floor, Main Building
Abstract:
Neutron stars are effectively cosmic laboratories to study the behaviour of matter under extreme conditions, far beyond the reach of present terrestrial nuclear or heavy-ion experiments. It is conjectured that exotic particles such as strange baryons or deconfined quark matter may appear in the ultra-high density environment of the neutron star interior, and this could in turn affect their observable properties. With the recent detection of gravitational waves from mergers of neutron stars in binary, a new window has opened up for multi-messenger astronomy complementary to conventional multi-wavelength electromagnetic observations, and provide important constraints on the theories of dense matter. I will discuss some of our recent investigations related to the implications of these recent multi-messenger observations on our understanding of nuclear and particle physics.
