EurophysicsNews, 2021 They are out there in the sky in huge numbers. They are the most astonishing objects in the universe. Their existence was predicted and understood before we detected them. They behave precisely as the theory predicted. Yet, we do not know what happens at

Journal of High Energy Physics, 2011 In this paper Janus black holes in AdS3 are considered. These are static solutions of an Einstein-scalar system with broken translation symmetry along the horizon. These solutions are dual to interface conformal field theories at finite temperature.

Physics Letters B, 2018 We propose a correspondence between an Anyon Van der Waals fluid and a (2+1) dimensional AdS black hole. Anyons are particles with intermediate statistics that interpolates between a Fermi-Dirac statistics and a Bose-Einstein one.

Multioscillating black holes [PDF]
Journal of High Energy Physics, 2021 Abstract We study rotating global AdS solutions in five-dimensional Einstein gravity coupled to a multiplet complex scalar within a cohomogeneity-1 ansatz. The onset of the gravitational and scalar field superradiant instabilities of the Myers-Perry-AdS black hole mark bifurcation points to black resonators and hairy Myers-Perry ...

The origins of massive black holes [PDF]
Nature Reviews Physics, 2021 Massive black holes (MBHs) inhabit galactic centres, and power luminous quasars and active galactic nuclei, shaping their cosmic environment with the energy they produce.

Constraints on primordial black holes [PDF]
Reports on progress in physics. Physical Society, 2020 We update the constraints on the fraction of the Universe that may have gone into primordial black holes (PBHs) over the mass range 10−5 to 1050 g. Those smaller than ∼1015 g would have evaporated by now due to Hawking radiation, so their abundance at ...

Parameter estimation of hairy Kerr black holes from its shadow and constraints from M87* [PDF]
, 2021 The recently obtained hairy Kerr black holes, due to additional sources or surrounding fluid, like dark matter, with conserved energy-momentum tensor, have a deviation U and primary hair ;0, apart from rotation parameter 0 and mass " . In the wake of the

Primordial Black Holes as Dark Matter: Recent Developments [PDF]
Annual Review of Nuclear and Particle Science, 2020 Although the dark matter is usually assumed to be made up of some form of elementary particle, primordial black holes (PBHs) could also provide some of it.

Primordial black holes as a dark matter candidate [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2020 The detection of gravitational waves from mergers of tens of Solar mass black hole binaries has led to a surge in interest in Primordial Black Holes (PBHs) as a dark matter candidate.

Gravitational waves from a universe filled with primordial black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Ultra-light primordial black holes, with masses m PBH < 109g, evaporate before big-bang nucleosynthesis and can therefore not be directly constrained. They can however be so abundant that they dominate the universe content for a transient period (before ...
