Observational appearances of an inner extremal regular black hole illuminated by various accretion flows
Dan Zhang, Guoyang Fu, Xi-Jing Wang +3
This paper investigates the observational appearances of an inner extremal regular black hole(IERBH) illuminated by various types of accretion models. The study reveals that when t…
Distinguishing black holes with and without spontaneous scalarization in Einstein-scalar-Gauss-Bonnet theories via optical features
Xi-Jing Wang, Yuan Meng, Xiao-Mei Kuang +1
Spontaneous scalarization in Einstein-scalar-Gauss-Bonnet theory admits both vacuum-general relativity (GR) and scalarized hairy black holes as valid solutions, which provides a di…
Using the shadow of a black hole to examine the energy exchange between axion matter and a rotating black hole
Xiao-Mei Kuang, Yuan Meng, Eleftherios Papantonopoulos +1
We find that a \textit{slowly} rotating axion-modified black hole resulting from the backreaction of an axion field on a rotating Kerr black hole can have a \textit{D-shaped} shado…
Images of hairy Reissner-Nordström black hole illuminated by static accretions
Yuan Meng, Xiao-Mei Kuang, Xi-Jing Wang +2
We investigate the shadow and optical appearance of the hairy Reissner-Nordström (RN) black hole illuminated by two toy models of static accretion. The hairy RN black hole was cons…
