“…The main aim of our work will be to investigate the behavior of axion-like particle dark matter model clouds, around the mimickers of rotating black holes, stationary axially symmetric wormholes. The work will provide some continuity with our previous studies [32], where we have paid attention to the main features of axionic clouds dark matter in the vicinity of magnetized rotating black holes.…”

“…The method in question has already been implemented in Python and tested for the numerical stability. The technical details, especially convergence tests of the numerical method are described in the Appendix of [32], where we studied the problem of axionlike particle clouds in the spacetimes of rotating magnetized black holes.…”

“…The dark matter model in question was widely elaborated in studies of black hole superradiance and light polarization effects, possible experimental signals of dark sector around these objects [32,[41][42][43][44][45], and neutron stars [46][47][48][49], as well as, the influence of axionic dark matter on the physics on early Universe and primordial black holes [50][51][52][53].…”

“…As in [32], where we have studied rotating magnetized black holes submerged into axionic dark matter cloud, one can introduce a static magnetic field to the system, which will be oriented along the rotation axis. It seems to be plausible from the point of astrophysical perspective and can be regarded as a starting point for studies of the magnetic field influence of the system in question.…”

“…We also observe the separation of the cloud from the surface of the throat in both cases. This allows us to notice some general wormhole related phenomena, which are present around the black holes [32]. Naturally we cannot speak in a fully general manner, as we only considered here merely two distinct gravitational backgrounds, which on the other hand should be treated as toy models.…”

The problem of the distribution of axionlike particle, being the model of dark matter, in the nearby of rotating wormholes has been investigated numerically. In the model in question the axion scalar is non-trivially coupled to the Maxwell gauge field. We consider two toy models of rotating wormholes embedded in magnetic field, Kerr-like and Teo rotating wormholes. Moreover one assumes that the matter fields will not backreact on the wormhole spacetimes, i.e., we shall study the problem in the probe limit case. We point out the differences in the distribution of dark matter comparing to the location of it in the vicinity of rotating magnetized black holes.

We present a novel interpretation of the thermodynamics of perfect fluid dark matter (PFDM) black hole based on Misner–Sharp energy and then investigate its evaporation behavior. We find that the ratio between dark sector initial density and black hole horizon radius significantly influences black hole evaporation behaviors. We demonstrate that the presence of the dark sector can significantly extend the lifetime of a black hole which is similar to the Reissner–Nordström case. Our work reformulates the thermodynamics of PFDM black holes and points out the existence of long-lived black holes in the presence of the dark sector.
