Workshop on Astro-Cosmo-Gravity

Talk

Relativistic density functionals based on baryon-meson Lagrangians can
be used to describe effectively dense matter in compact stars
including hyperonic and Delta-resonance degrees of
freedom. These can be supplemented with a first-order phase transition
to quark matter at high densities to describe hybrid compact stars.
I will discuss how the mass-radius and tidal deformability...

99. Directional dark matter searches with the NEWSdm Experiment

Workshop on Astro-Cosmo-Gravity

Talk

The nature of dark matter is one of the most relevant open problems both in cosmology and particle physics. Many different experimental techniques have been designed and built to detect Weakly Interactive Massive Particles (WIMPs) as dark matter candidates via their scattering with detector atoms. The NEWSdm experiment, located in the Gran Sasso underground laboratory in Italy, is based on a...

164. An overview of CTAO Science

Talk

The Cherenkov Telescope Array Observatory (CTAO) will be the next-generation ground-based gamma-ray observatory. CTAO is an array of Imaging Cherenkov Telescopes (IACTs) with sites in the northern and southern hemispheres covering the entire sky. Spanning the energy range from 20 GeV to 300 TeV and offering sensitivity one order of magnitude better than current-generation Imaging Cherenkov...

141. Formation of twin stars in low-mass X-ray binaries and in supernova explosions

Workshop on Astro-Cosmo-Gravity

Talk

We explore the conditions under which a first-order deconfinement phase transition in cold and warm neutron star cores would lead to the formation of a third family of compact stars and thus to cold and thermal twin stars. When this transition occurs in a low-mass X-ray binary system, possibly coupled with secondary kick mechanisms such as neutrino or electromagnetic rocket effects, it may...

142. X-ray Emission spectrum from strongly magnetized neutron stars due to axion to photon conversion

, We employ here the modified system of Tolman–Oppenheimer–Volkoff (TOV) equations due to the presence of a magnetic field to study the emission properties of the strongly magnetized neutron stars (NSs). We have considered the distance-dependent magnetic field in the modified TOV system of equations. We used three different equations of states (EoSs), namely APR, FPS, and SLY to solve these...
