Quantum gravity represents the frontier where the very large meets the very small, attempting to unify Einstein's theory of gravity with the strange rules of quantum mechanics. This field explores the fundamental fabric of spacetime, seeking to understand how the universe behaves at its most extreme scales, from the heart of black holes to the moment of the Big Bang. Because these concepts often involve complex mathematics, they can feel distant to non-specialists, yet they hold the key to a complete picture of physical reality.

This paper describes and classifies five-dimensional maximal supergravities with gauge groups contained in , uncovering a new family of theories and identifying their supersymmetric anti-de Sitter vacua as dual to superconformal phases of the M5-brane field theory.
This paper provides comprehensive support material for the May 2025 Galileo Galilei Institute school on asymptotic symmetries and flat holography, offering a pedagogical introduction to gauge theories, the covariant phase space formalism, and BMS symmetries, alongside original derivations of the BMS group using Minkowski space and an integral Hamiltonian generator for scalar fields on null hypersurfaces.
This study employs pseudo-Newtonian potentials and dynamical analysis tools like Poincaré sections and Maximum Lyapunov Exponents to demonstrate how the spin of a central supermassive black hole, modeled by the Artemova-Bjornsson-Novikov potential within a prolate shell-like halo, modulates the transition between order and chaos in the orbits of nearby particles.
This study investigates the chaotic dynamics of galactic centers by modeling a spinning supermassive black hole and an asymmetric nuclear star cluster, revealing through stability analysis and basin of convergence methods how the black hole's spin significantly reshapes orbital stability and chaos in the presence of multipolar mass distributions.
This paper investigates how the thermal environment of the early Universe modifies the evaporation history of primordial black holes, thereby significantly altering the timing and spectral properties of the stochastic gravitational wave background they produce compared to standard vacuum evaporation models.
This paper numerically investigates the displacement memory effect induced by a wave pulse in regular black hole spacetimes, revealing that the resulting net displacement depends on the regularization parameter and pulse height, and differs significantly from that observed in singular black holes.
This study demonstrates that deviations from the standard primordial power spectrum can significantly enhance or suppress the detectability of non-trivial cosmic topologies in CMB temperature data, highlighting the critical need to account for primordial spectrum uncertainties in topology searches.
This paper investigates the dynamics and gravitational wave signatures of spinning particles in Deser-Woodard nonlocal gravity, demonstrating that specific nonlocal parameters significantly alter orbital stability and induce distinguishable phase shifts in gravitational waveforms compared to general relativity.
This paper investigates the dynamics of charged null dust collapse in spherical symmetry by establishing that any timelike curve can serve as a bounce hypersurface for such fluids and formulating a free boundary problem to describe the conditional formation of these surfaces within Reissner-Nordström spacetime.
This paper investigates the hydrodynamics of relativistic, charged, superheated bubbles in neutron star mergers, identifying unique pressure behaviors and metastable fluid regions distinct from supercooled bubbles while analyzing their impact on gravitational wave production efficiency.
