Hawking-Unruh Hadronization and Strangeness Production in High Energy Collisions by Paolo Castorina, Helmut Satz

“…Indeed, the interpretation of quark (q)-antiquark (q̅) pairs production, by the sequential string breaking, as tunneling through the event horizon of colour confinement leads to thermal behavior with a universal temperature, T≃170 Mev, related to the quark acceleration, a, by T=a/2π. …”

All near-horizon symmetries of the Schwarzschild black hole in linearised gravity by Ankit Aggarwal, Nava Gaddam

“…We study large diffeomorphisms of linearised perturbations of the Schwarzschild black hole in a partial wave basis and in a gauge that allows for gravitational radiation crossing the event horizon. This setup is ideally suited for studying processes involving near-horizon gravitons like scattering and black hole evaporation. …”

Rips and regular future scenario with holographic dark energy: a comprehensive look by I. Brevik, Maxim Khlopov, S. D. Odintsov, Alexander V. Timoshkin, Oem Trivedi

“…We discuss these events in the realm of the generalized Nojiri–Odintsov cutoff and also for the more primitive holographic cutoffs like Hubble, particle and event horizon cutoffs. We also discuss the validity of the generalized second law of thermodynamics and various energy conditions in these regimes. …”

Quasinormal modes of three $$(2+1)$$ ( 2 + 1 ) -dimensional black holes in string theory, conformal gravity, and Hu–Sawicki F(R) theory via the Heun function by F. Naderi, A. Rezaei-Aghdam

“…The distribution of the quasinormal modes has been clarified to satisfy the boundary conditions that require ingoing and decaying waves at the event horizon and conformal infinity, respectively. It turned out that the procedure based on the Heun function, beside reproducing the previously known results obtained via hypergeometric function for the BTZ and Lifshitz black hole solution in conformal gravity, brings up new families of quasinormal frequencies, which can also contain purely imaginary modes. …”

Circular light orbits of a general, static, and spherical symmetrical wormhole with $$Z_2$$ Z 2 symmetry by Naoki Tsukamoto

“…Abstract Recently, the ring images or the shadow images of the centers of the galaxy M87 and the Milky way have been reported by Event Horizon Telescope Collaboration. It is believed that the ring images imply that the central objects form unstable light circular orbits. …”

Thermodynamic Relations for Kiselev and Dilaton Black Hole by Bushra Majeed, Mubasher Jamil, Parthapratim Pradhan

“…We have calculated the products relating the surface gravities, surface temperatures, Komar energies, areas, entropies, horizon radii, and the irreducible masses at the Cauchy and the event horizons. It is observed that the product of surface gravities, product of surface temperature, and product of Komar energies at the horizons are not universal quantities for the Kiselev solutions while products of areas and entropies at both the horizons are independent of mass of the above-mentioned black holes (except for Schwarzschild black hole surrounded by quintessence). …”
