Théorie

Lorentz invariance is the cornerstone of modern physics.

Nuclear theory and experiments constrain dense matter near nuclear saturation density, while neutron star observations probe the higher densities found inside stars.

Tidal effects shape the late inspiral of binaries containing neutron stars and carry information about the neutron-star equation of state

We investigate the thermal evolution of quark stars with and without a hadronic crust using an equation of state derived from perturbative QCD that incorporates the runn

The construction of a reliable renormalization group (RG) flow for discrete gravity models that preserves their under

Neutrinos play an important role in compact star
astrophysics: neutrino-heating is one of the main ingredients in
core-collapse supernovae, neutrino-matter interactions determine the
composition of matter in binary neutron star mergers and have among
others a strong impact on conditions for heavy element nucleosynthesis
and neutron star cooling is dominated by neutrino emission except for
very old stars. Many works in the last decades have shown that in
dense matter medium effects considerably change the neutrino-matter

The Diffuse Supernova Neutrino Background (DSNB) constitutes a steady and isotropic flux of
neutrinos originating from all past core-collapse supernovae across the observable universe [1,
2]. The DSNB remains undetected despite decades of theoretical development and increasingly
stringent limits from Super-Kamiokande [3], which now lie only a few factors above theoretical
predictions. Its eventual observation would provide a unique probe of core-collapse dynamics
and neutrino properties integrated over cosmological distances [4], while any deviation from
