Images of shadow and thin accretion disk around Bardeen black hole surrounded by perfect fluid dark matter
Haiyuan Feng, Ziqiang Cai, Hao-Peng Yan +2
We investigate the shadow and optical appearance of Bardeen black hole (BH) immersed in perfect fluid dark matter (PFDM). Using EHT observations of M87* and Sgr A*, we constrain th…

Choked accretion onto Kerr-Sen black holes in Einstein-Maxwell-dilaton-axion gravity
Haiyuan Feng, Yingdong Wu, Rong-Jia Yang +1
We investigate the process of an ultrarelativistic fluid accreted onto axisymmetric Kerr-Sen black holes in Einstein-Maxwell-dilaton-axion theory. We obtain the solution describing…
