“…In general, the shadow shape of a black hole depends on whether the black hole rotates or not. For a static and spherically symmetric black hole, 3 such as the EYM black holes we are dealing with, the shadow has the spherical symmetry and is described by a photon sphere. From the definition of a shadow radius, or directly deriving from Eq.…”

Null geodesics, quasinormal modes of a massless scalar field perturbation, and the correspondence with shadow radii are investigated in the background spacetime of high-dimensional Einstein-Yang-Mills black holes. Based on the properties of null geodesics, we obtain the connection between the radius of a photon sphere and the radius of a horizon in the five-and six-dimensional Einstein-Yang-Mills spacetimes. Especially in the five-dimensional case, there exist two branches for the radius of a photon sphere, but only the branch outside the event horizon satisfies the condition of circular null geodesics. Moreover, we find no reflecting points of shadow radii and no spiral-like shapes on the complex plane of quasinormal frequencies and verify the correspondence between the quasinormal modes in the eikonal limit and shadow radii in high-dimensional Einstein-Yang-Mills spacetimes.

In this work a static spherically symmetric black hole's solution within the Einstein-Maxwell-Yang-Mills-dilaton theory is derived. The obtained solution is examined, in particular, we have calculated the Kretschmann scalar which allowed us to characterize singularity points. Using the obtained black hole's solution we have studied its thermodynamics. Namely, the temperature was calculated, the first law was written, and the heat capacity was studied. The extended thermodynamics approach is utilized to obtain the equation of state. Within the extended thermodynamics the Gibbs free energy is derived and investigated. The analysis of the Gibbs free energy shows that below the critical temperature besides the first order phase transition in addition the zeroth order phase transition occurs, what is typical for other types of black holes with dilaton fields. Finally, we have shown that the critical exponents take the same values as for other types of the dilaton black holes.

“…Usually, a vdW-like small-large black hole (SBH-LBH) phase transition can be observed in thermodynamical systems including black holes whenever Λ behaves as a thermodynamical pressure. This type of phase transition has been studied extensively in the background spacetime of various black hole solutions (for instance, see an incomplete list [12][13][14][15][16][17][18][19][20][21][22][23][24][25] and references therein written during recent years).…”

By considering a small correction to the Maxwell field, we show that the resultant black hole solutions (also known as the asymptotically Reissner-Nordström black holes) undergo the reentrant phase transition and can have a novel phase behavior. We also show that such a small nonlinear correction of the Reissner-Nordström black holes has high effects on the phase structure of the solutions. It leads to a new classification in the canonical ensemble of extended phase space providing the values of the nonlinearity parameter α being α 4q 2 /7. We shall study these three classes and investigate deviations from those of the standard Reissner-Nordström solutions. Interestingly, we find that there is the reentrant phase transition for α < 4q 2 /7, and for the case of α = 4q 2 /7 there is no phase transition below (at) the critical point. For the last case, one finds that small and large black holes are thermodynamically distinguishable for temperatures and pressures higher than the critical ones.
