The speed of sound in the core of neutron stars is a key quantity for providing a characteristic signature of a possible phase transition or the occurance of non-standard degrees of freedom in dense baryonic matter. The first part of this talk presents a status summary of results from a systematic Bayes inference analysis of the equation-of-state based on observational data. In the second part...
Terrestrial experiments, particularly heavy-ion collision experiments, suggest the appearance of strangeness containing particles, such as hyperons, in dense matter. The ultrahigh density core of Neutron Stars is the ideal environment to search for strange matter. Over the past decade, astrophysical observations of Neutron Stars across multiple wavelengths of the electromagnetic spectrum have...
The particle content of the interior of neutron stars is still unknown, especially in the case of very massive stars. It is clear that if hyperons or quarks are present, they will affect the dynamics of the merger of two neutron stars. The impact on the observables and even more the prospects for detectability are possibly very interesting, but also uncertain. In this talk, I will illustrate...
The coalescence of a binary system of neutron stars represents a natural laboratory to study hot and ultra-dense matter. Under these extreme conditions, exotic species like hyperons may be present. In this work, we present a comprehensive study of hyperons in neutron star mergers, focusing on the thermal impact they have on the Equation of State. The presence of the hyperons in a hot dense...
In the emerging field of astrophysics, understanding the intricate nature of neutron stars (NSs) and their equations of state (EoS) remains a challenging task. This talk presents an integrated approach based on deep learning and Bayesian neural networks (BNNs) to unravel the NS composition.
Our research is built upon two key studies. The first exploits BNNs' unique capability to provide...
