New analytical model of rotating black hole with dark matter halo: constraints from EHT observations and accretion disk

Uktamjon Uktamov, Sanjar Shaymatov, Bobomurat Ahmedov +1

In this paper, we start from a static black hole (BH) immersed in a Deanne-type dark matter (DM) halo and employ the Newman-Janis algorithm (NJA) to generate the rotating black hol…
