Emergence of Gravity's Dynamical and Topological Sectors from Pre-geometry
Andrea Addazi, Giuseppe Meluccio
We identify the complete set of fundamental building blocks for a 4D pre-geometric theory of gravity. Based on a gauge theory of or coupled to a Higgs-like fiel…
Poincaré asymptotic expansion in black hole theory
Giampiero Esposito, Marco Refuto
In studying the dynamics of fields in black hole theory, the method of separation of variables makes it possible to isolate the radial part of the full solution in many important p…
Gravitational lensing by extremal rotating black holes in the strong deflection limit
Fabiano Feleppa, Valerio Bozza, Welmoed Marit de Graaf
In the strong deflection regime, light rays passing close to an astrophysical black hole may remain trapped near unstable photon orbits for a long time before escaping to infinity.…
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.…
Primary Constraints of Newer General Relativity
Carmen Ferrara, Alexey Golovnev, María José Guzmán
We study the primary constraint structure of Newer General Relativity, a gravity theory based on a torsionless teleparallel geometry. The gravitational action is built from a scala…
Mechanical Long Baseline Differential Gradiometers as Low Frequency Gravitational Wave Detectors
Enrico Calloni, Annalisa Allocca, Antonino Chiummo +12
We present a new differential mechanical gradiometer for the detection of low-frequency Gravitational Waves. The frequency range is 0.05 to 1 Hz, a frequency gap not covered either…
Friedmann cosmology with fluids and hyperfluids
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
We discuss flat Friedmann-Lemaitre-Robertson-Walker (FLRW) metric-affine cosmology where the metric and connection as well as the matter energy-momentum and hypermomentum all obey…
Extended Theories of Electrodynamics in Gravity
Francesco Bajardi, Micol Benetti, Salvatore Capozziello +1
Within the general framework of gravity, we introduce a function of the electromagnetic curvature invariant that couples minimally to gravitation to ensure a…
Energy Conditions in Gauss-Bonnet Gravity
Francesco Bajardi
We study the Energy Conditions in modified gravity, with being the topological Gauss-Bonnet term. Then we use the cosmographic parameters to constrain the functional for…
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…
Constraining -Exponential Inflation with the latest ACT observations
Jureeporn Yuennan, Farruh Atamurotov, Salvatore Capozziello +1
Recent observations from the Atacama Cosmology Telescope (ACT), especially when combined with DESI baryon acoustic oscillation data, indicate a scalar spectral index higher t…
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…
Confronting eikonal and post-Kerr methods with numerical evolution of scalar field perturbations in spacetimes beyond Kerr
Ciro De Simone, Sebastian H. Völkel, Kostas D. Kokkotas +2
The accurate computation of quasinormal modes from rotating black holes beyond general relativity is crucial for testing fundamental physics with gravitational waves. In this study…
