Rotating Weyssenhoff fluids in linearized Einstein-Cartan theory
Emmanuele Battista, Salvatore Capozziello, Francesco Giovinetti
The Weyssenhoff fluid expands the ordinary perfect-fluid description of general relativity by taking into account the intrinsic spin of its constituent particles. Within the linear…
Effective Matter Conversion in Gravitational Collapse and the Dynamical Formation of Regular Black Holes
Emmanuele Battista, Ali Ovgun, Vitalii Vertogradov
We study inverse source reconstruction in generalized Vaidya spacetimes. A prescribed density fixes the mass and tangential pressure, while a two-sector decomposition determines a…
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 of Kerr-Schild type in general relativity that satisfy the weak energy condition. O…
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…
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…
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…
Null geodesics, causal structure, and matter accretion in Lorentzian-Euclidean black holes
Salvatore Capozziello, Emmanuele Battista, Silvia De Bianchi
Recently, we introduced the Lorentzian-Euclidean black hole, a static and spherically symmetric solution of vacuum Einstein equations that exhibits a change in metric signature acr…
Atemporality from Conservation Laws of Physics in Lorentzian-Euclidean Black Hole
Silvia De Bianchi, Salvatore Capozziello, Emmanuele Battista
Recent results have shown that singularities can be avoided from the general relativistic standpoint in Lorentzian-Euclidean black holes by means of the transition from a Lorentzia…
Complex degenerate metrics in general relativity: a covariant extension of the Moore-Penrose algorithm
Arthur Garnier, Emmanuele Battista
The Moore-Penrose algorithm provides a generalized notion of an inverse, applicable to degenerate matrices. In this paper, we introduce a covariant extension of the Moore-Penrose m…
Signatures of modified gravity from the gravitational Aharonov-Bohm effect
Kimet Jusufi, Abdelrahman Yasser, Emmanuele Battista +1
To date, no observational confirmation of dark matter particles has been found. In this paper, we put forward an alternative approach to inferring evidence for dark matter through…
Dynamical features and shadows of quantum Schwarzschild black hole in effective field theories of gravity
Zi-Liang Wang, Emmanuele Battista
We investigate the properties of the Schwarzschild black hole geometry involving leading one-loop long-distance quantum effects, which arise within the framework of effective field…

Emmanuele Battista, Salvatore Capozziello, Abdelghani Errehymy
We explore wormhole solutions sourced by Casimir energy density involving generalized uncertainty principle corrections within the framework of Rastall-Rainbow gravity. The questio…
Avoiding singularities in Lorentzian-Euclidean black holes: the role of atemporality
Salvatore Capozziello, Silvia De Bianchi, Emmanuele Battista
We investigate a Schwarzschild metric exhibiting a signature change across the event horizon, which gives rise to what we term a Lorentzian-Euclidean black hole. The resulting geom…
Quantum Schwarzschild geometry in effective-field-theory models of gravity
Emmanuele Battista
The Schwarzschild geometry is investigated within the context of effective-field-theory models of gravity. Starting from its harmonic-coordinate expression, we derive the metric in…
One-loop effective action of the IKKT model for cosmological backgrounds
Emmanuele Battista, Harold C. Steinacker
We study cosmological solutions of the IKKT model with FLWR geometry, taking into account one-loop corrections. A previously discussed covariant quantum spacetime is found t…
