On emergent conformal symmetry near the photon ring
Bin Chen, Yehui Hou, Zezhou Hu
In this note we revisit the emergent conformal symmetry in the near-ring region of warped spacetime. In particular, we propose a novel construction of the emergent near-ring $sl(2,…
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…
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…
