An Interior Solution for the Kerr Metric: A Novel Approach by Yu-Ching Chou

“…Our findings reveal anisotropic fluid properties and energy condition behaviors in specific space-time regions, providing insights into the strong-field regime of rotating black holes. The proposed solution offers a more realistic description of rotating black hole interiors, with implications for understanding compact astrophysical objects.…”

Complexity geometry and Schwarzian dynamics by Henry W. Lin, Leonard Susskind

“…In many setups, this “Schwarzian” variable can be interpreted as the extremal volume of the dual black hole, and the resulting dynamics is simply that of a 1D Newtonian particle in an exponential potential. …”

Can the New Neutrino Telescopes Reveal the Gravitational Properties of Antimatter? by Dragan Slavkov Hajdukovic

“…If there is such a gravitational repulsion, the gravitational field, deep inside the horizon of a black hole, might create neutrino-antineutrino pairs from the quantum vacuum. …”

Stabilization of spherically symmetric static Boson stars by Coleman-Weinberg self-interaction potential by Firoozeh Eidizadeh, Hossein Ghaffarnejad

“…Our motivation in this work is due to the great importance of relativistic boson stars as fierce competitors of black holes. From theoretical perspective, they described by complex Klein Gordon (KG) scalar fields interacting with curved background in general form. …”

Phase Transition and Entropy Force between Two Horizons in (n+2)-Dimensional de Sitter Space by Yang Zhang, Wen-qi Wang, Yu-bo Ma, Jun Wang

“…The result shows that the accelerating cosmic expansion can be attained by the entropy force arisen from the interaction between horizons of black holes and our universe, which provides a possible way to explain the physical mechanism for the accelerating cosmic expansion.…”

On Boundedness of Entropy of Photon Gas in Noncommutative Spacetime by Kazi Ashraful Alam, Mir Mehedi Faruk

“…As a result, the reported analogy between thermodynamics of photon gas in such NC spacetime and Bekenstein-Hawking entropy of black holes should be disregarded.…”

Distinguishing Compact Objects in Extreme-Mass-Ratio Inspirals by Gravitational Waves by Lujia Xu, Shucheng Yang, Wenbiao Han, Xingyu Zhong, Rundong Tang, Yuanhao Zhang

“…Therefore, our findings suggest that it is possible to distinguish primordial black holes from white dwarfs, and, under certain conditions, neutron stars can also be differentiated from primordial black holes.…”

Aspects of a novel nonlinear electrodynamics in flat spacetime and in a gravity-coupled scenario by Anjan Kar

“…Moreover, a minimal coupling of Einstein’s General Relativity (GR) with this NLE results in solutions of regular black holes or naked singularities, depending on whether the source is a nonlinear magnetic monopole or an electric charge, respectively.…”

A Cosmological Scaling Relation for Describing the Late Time Dynamics by Gerardo Cristofano, Orlando Luongo

“…A scaling relation between mass and minimal information of a given system is inferred from primordial black holes. Extending its validity, it is possible to describe different stages of the universe evolution. …”

Discovering and Characterizing Hidden Variables Using a Novel Neural Network Architecture: LO-Net by Soumi Ray, Tim Oates

“…Scientific inquiry has uncovered many such entities, such as black holes and dark matter. We claim that theoretical entities, or hidden variables, are important for the development of concepts within the lifetime of an individual and present a novel neural network architecture that solves three problems related to theoretical entities: (1) discovering that they exist, (2) determining their number, and (3) computing their values. …”

D’Alger à Damas, des auteurs en mal d’archives ? by Ines Horchani

“…In any case, marks from the colonial past are tangible and can resemble black holes, scars, rifts, or stratum… We will show that these authors from an Arab world, not yet completely restored from colonization, make quite variable usage of real archives (academic or non-academic) and also resort to the creation of imaginary archives. …”
