Energy conditions in static, spherically symmetric spacetimes and effective geometries
Zi-Liang Wang, Emmanuele Battista
Classical energy conditions are investigated in generic static and spherically symmetric spacetimes. In setups with nonconstant , the appearance of horizons can sign…
Equivalence Principle violation in metric-affine gravity and finite-temperature effects
Emmanuele Battista, Roberto Campagnola, Salvatore Capozziello +1
Possible violations of the equivalence principle are investigated within the framework of metric-affine gravity and their connection to finite-temperature effects are highlighted.…
Families of regular spacetimes and energy conditions
Zi-Liang Wang, Emmanuele Battista
We present a systematic method for constructing static, spherically symmetric regular spacetimes in general relativity satisfying the weak energy condition. Our approach relies on…
Shadow signatures and energy accumulation in Lorentzian-Euclidean black holes
Emmanuele Battista, Salvatore Capozziello, Che-Yu Chen
The Lorentzian-Euclidean black hole has been recently introduced as a geodesically complete spacetime featuring a signature shift at the event horizon where causal geodesics are pr…
Minisuperspace Cosmology in Extended Geometric Trinity of Gravity
Emmanuele Battista, Salvatore Capozziello, Stefano Pastore
We investigate Extended Geometric Trinity of Gravity at both classical and quantum cosmological levels using the minisuperspace approach. Adopting Noether symmetries to select viab…
NovaMoon: A Strategic Lunar Reference Station for Positioning, Timing, and Largely Enhanced Science in the Earth-Moon System
Serena Molli, Agnès Fienga, Pascale Defraigne +82
The renewed interest in lunar exploration and the development of future lunar communication and navigation services highlight the need for a precise, stable, and interoperable geod…
