Enhanced adiabatic index for hot neutron-rich matter from microscopic nuclear forces

**theory**and find that the results are systematically larger than from typical mean

**field**models. We start by constructing the finite-temperature equation of state from chiral two- and three-nucleon forces, which we then use to fit a class of extended Skyrme energy density functionals. This allows for modeling the thermal index across the full range of densities and temperatures that may be probed in simulations of core-collapse supernovae and neutron star mergers, including the low-density inhomogeneous mixed phase. For uniform matter we compare the results to analytical expressions for $\Gamma_{\mathrm{th}}$ based on Fermi liquid

**theory**. The correlation between the thermal index and the effective masses at nuclear saturation density is studied systematically through Bayesian modeling of the nuclear equation of state. We then study the behavior of $\Gamma_{\mathrm{th}}$ in both relativistic and non-relativistic mean

Interpreting cosmological tensions from the effective **field** **theory** of

**field**

**theory**(EFT). We apply the EFT approach, which allows to investigate the evolution equations at the background and perturbation levels in a systematic way, and examine the conditions followed by the coefficients of various possibly involved operators such that cosmological tensions can be relaxed. Following these observations we construct concrete models of Lagrangians of torsional gravity. Specifically, we consider the parametrization $f(T)=-T -2\Lambda/M_P^2 +\alpha T^\beta$, where two out of the three parameters are independent (in which an additional term of the form $cT^{1/2}$ can be added). This model can efficiently fit observations solving all statistical tensions. To our knowledge, this is the first time where a modified gravity

**theory**can alleviate both $H_0$ and $\sigma_8$ tensions simultaneously, hence offering an additional argument in favor of gravitational modification.
