Critical behavior of AdS black holes surrounded by dark fluid with Chaplygin-like equation of state
Xiang-Qian Li, Hao-Peng Yan, Li-Li Xing +1
Supposing the existence of Dark Fluid with a Chaplygin-like equation of state (CDF) as a cosmic background, we obtain a static spherically-symmetric black hole (BH) soluti…
Photon emissions from Kerr equatorial geodesic orbits
Yanming Su, Minyong Guo, Haopeng Yan +1
We consider the light emitters moving freely along the geodesics on the equatorial plane near a Kerr black hole and study the observability of these emitters. To do so, we assume t…
Image of Kerr-Melvin black hole with thin accretion disk
Yehui Hou, Zhenyu Zhang, Haopeng Yan +2
In this present work, we study the observational appearance of Kerr-Melvin black hole (KMBH) illuminated by an accretion disk. The accretion disk is assumed to be located on the eq…
Shadows of Kerr black holes with a Gaussian-distributed plasma in the polar direction
Zhenyu Zhang, Haopeng Yan, Minyong Guo +1
In this work, we study the shadow of Kerr black hole surrounded by an axisymmetric plasma, whose density takes a Gaussian distribution in the polar direction. Along the radial dire…
Polarized Images of Synchrotron Radiations in Curved Spacetime
Zezhou Hu, Yehui Hou, Haopeng Yan +2
In this work, we derive two formulas encoding the polarization direction and luminosity of synchrotron radiations from the moving electrons in curved spacetime under the geometric…
Multi-level images around Kerr-Newman black holes
Yehui Hou, Peng Liu, Minyong Guo +2
We study the lensing effects of Kerr-Newman (KN) black holes and the multi-level images of luminous sources around the black holes. We obtain the analytic forms of the lens equatio…
