Quasiperiodic oscillations as probes of rotating black holes in exponential dark matter environments

Madina Alimkulova, Kuantay Boshkayev, Sholpan Gumarova +2

We construct the rotating counterpart of a black hole embedded in a dark-matter halo with the exponential-sphere profile $\rho ={\rho }_0{e}^{-r/r_0}$, using the Newman--Janis algorithm in the…
