Topological classes of rotating black holes
D Wu - Physical Review D, 2023 - APS
In this paper, we investigate the topological numbers for the singly rotating Kerr black holes
in all dimensions and the four-dimensional Kerr-Newman black hole. We show that for …

Inflation and primordial black holes
We review conceptual aspects of inflationary scenarios able to produce primordial black
holes by amplifying the size of curvature fluctuations to the level required to trigger black …

First Sagittarius A* event horizon telescope results. IV. Variability, morphology, and black hole mass
In this paper we quantify the temporal variability and image morphology of the horizon-scale
emission from Sgr A*, as observed by the EHT in 2017 April at a wavelength of 1.3 mm. We …

Observational evidence for cosmological coupling of black holes and its implications for an astrophysical source of dark energy
Observations have found black holes spanning 10 orders of magnitude in mass across most
of cosmic history. The Kerr black hole solution is, however, provisional as its behavior at …

Superradiant evolution of the shadow and photon ring of Sgr
Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant
instability, which can lead to a time evolution of the supermassive BH shadow. We study …
