DESCRIPTION:Speakers: Ritam Mallick (IISER Bhopal\, Índia)\n\nNeutron sta
 rs (NSs) are among the most fascinating and extreme astrophysical objects 
 in the Universe\, providing a unique natural laboratory to study matter un
 der conditions unattainable on Earth. Over the last decade\, rapid advance
 s in multi-messenger astronomy have transformed our understanding of dense
  matter physics\, connecting astrophysics\, nuclear physics\, particle phy
 sics\, and general relativity in unprecedented ways. Recent observations f
 rom the Neutron Star Interior Composition Explorer (NICER)\, which measure
 s neutron star masses and radii with high precision\, together with gravit
 ational-wave detections from binary neutron star mergers such as GW170817\
 , have placed stringent constraints on the equation of state (EoS) of matt
 er at supranuclear densities. These observations have opened a new era in 
 the study of compact stars\, where electromagnetic and gravitational-wave 
 signals jointly provide insights into the microscopic properties of ultra-
 dense matter. In this presentation\, I will discuss how future detections 
 of post-merger gravitational-wave signals from binary neutron star mergers
  may help uncover one of the long-standing questions in nuclear and partic
 le physics: the existence of phase transitions in matter at extreme densit
 ies\, including the possible emergence of exotic phases such as deconfined
  quark matter. I will also discuss how modern machine learning techniques 
 can be utilised to solve the inverse problem of neutron stars — namely\,
  constraining the underlying microphysics and dense-matter equation of sta
 te directly from astrophysical observations. Particular emphasis will be p
 laced on combining NICER and gravitational-wave observations to infer neut
 ron star properties in a model-informed yet data-driven framework.\n\nhttp
