Project description
Unravelling the mystery of Neutron stars through gravitational waves
Neutron stars (NSs) are some of the densest objects in the Universe, yet their interiors remain a mystery. Recent theories suggest that heavy NSs could contain quark matter, and possibly even dark matter. With advancements in gravitational wave (GW) observatories like LIGO, scientists now have the opportunity to study the dynamic imprint of compact object binary mergers, offering new insights into NS composition. Supported by the Marie Skłodowska-Curie Actions programme, the CosmicBells project aims to fill this gap by examining how tidal oscillations in NSs influence GW signals. The project will use cutting-edge theoretical methods to predict gravitational-mode oscillations in exotic matter-admixed NSs, providing a unique opportunity to probe their mysterious interiors.
Objective
Neutron stars (NSs) are among the densest objects in our Universe, yet what constitutes their interior remains unanswered. Recent studies suggest the existence of quark matter inside the heaviest NSs, while there is growing speculation about the presence of dark matter inside them. In addition to state-of-the-art electromagnetic experiments like NICER, we are now, for the first time, able to observe the evolution of binary NSs using gravitational waves (GWs) as well. With the advancement of GW observatories like LIGO, and the upcoming third-generation detectors on the horizon, there is now a unique opportunity to explore NS composition through their dynamical imprint on GW signals from compact object (CO) binary mergers. Yet, most theoretical efforts are still focused on static properties of NSs, which are unable to provide detailed information on their composition. The CosmicBells project seeks to address this gap by answering the critical question: what can we learn about exotic matter inside NSs by observing the impact of tidal oscillations on the GW signals of CO binaries? As a Marie Curie Fellow I will achieve this goal by providing theoretical predictions on the properties of gravitational-mode (g-mode) oscillations in exotic matter admixed NSs using state-of-the-art field theoretical methods. I will also develop a few-body model to simulate the evolution of dynamically formed CO systems, focusing on the effect of g-mode tides. Working alongside Prof. Johan Samsing at the Niels Bohr Institute, I will be provided with the ideal research environment to carry out this project. The proposed research will present a novel method to study the impact of g-mode tides in CO systems, which might serve as beacons to pinpoint the existence of exotic matter in NSs.
