Note on regular magnetic black hole
A non-singular magnetic black hole in nonlinear electrodynamics has been introduced recently whose Lagrangian contains an exponential factor [15]. We show that such regular black holes are available without resorting to a transcendental factor.

Modeling the black holes surrounded by a dark matter halo in the galactic center of M87
In this paper, the structure of a dark matter halo can be well described by the mass model of M87 and the Einasto profile for the cold dark matter model, i.e., $$\rho _{\text {eina}} (r)=\rho _\text {e} \exp ( -2 \alpha ^{-1} ((r/r_\text {e})^\alpha -1 )

Unruh thermal hadronization and the cosmological constant
We use black holes with a negative cosmological constant to investigate aspects of the freeze-out temperature for hadron production in high energy heavy-ion collisions.

Photoswitchable Conductive Metal–Organic Frameworks
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.

On Einstein-non linear-Maxwell-Yukawa de-Sitter black hole thermodynamics
We investigate the thermodynamics of the Einstein-non linear-Maxwell-Yukawa black hole solution in de Sitter spacetime. After presenting the black hole solution and its horizons, we use different thermodynamical points of view to probe the phase ...

Exact anyon black hole solutions [PDF]
Abstract We present the exact anyon solutions and study their energy conditions. It is shown that the exact anyon VdW solutions with $$b>0$$ b>0 are physically un-acceptable. Especially for the reduced case $$b=0$$ b=0 , after carefully studying its energy conditions, geometric quantities and horizon structure, we conclude that there is an anyon black ...
