We prove under certain weak assumptions a black hole no-hair theorem in spherically symmetric spacetimes for self-gravitating time-dependent multiple scalar fields with an arbitrary target space admitting a Killing field with a non-empty axis and arbitrary non-negative potential invariant under the ...
In the 1960s, physicist John Wheeler suggested that black holes "have no hair," meaning that each particular cosmic object could only be distinguished from its brethren by its spin, angular momentum and mass. Any other differentiating information about a black hole is considered "hair," and is...
Using the WKB method, Prony method, Lyapunov exponent, and Weak Gravity Conjecture (WGC), the behavior of a short-hair black hole under different parameter conditions was systematically analyzed. Numerical results indicate that as the charge Q of the short-hair black hole approaches its extremal ...

Black holeʼs 1/N 1 / N mathContainer Loading Mathjax hairAccording to the standard view classically black holes carry no hair, whereas quantum hair is at best exponentially weak. We show that suppression of hair is an artifact of the semi-classical treatment and that in the quantum ...
We present a non-perturbative proof of the no hair theorems corresponding to scalar and Proca fields for stationary axisymmetric de Sitter black hole spacetimes. Our method also applies to asymptotically flat and under a reasonable assumption, to asymptotically anti-de Sitter spacetimes....
The Einstein-Skyrme system is known to possess black hole solutions with Skyrme hair. The spherically symmetric black hole skyrmion with B=1 was the first discovered counter example of the no-hair conjecture for black holes. Recently we found the B=2 axially symmetric black hole skyrmion. In ...
Over the years, scientists have looked for ways around the no-hair theorem via various loopholes, one of which is the possible existence of scalar fields that could interact with a black hole. We know of one scalar field that exists, namely the Higgs field, for which the force carrier is...
1 Introduction The no-hair theorem states that the black holes in Einstein– Maxwell theory are characterized by only their mass, electric charge, and angular momentum [1–4]. All other observable parameters as regards a black hole are hidden in the event horizon, i.e. the contributions from...
This leads to the forma- tion of an extreme black hole. The presence of dark matter, however, has minimal effect on the event horizon. Moreover, in the M87 as the spin parameter a increases, the black hole shadow deviates increasingly from a standard circle, with larger spin parameters ...
