Polarized image of synchrotron radiations of hotspots in Schwarzschilld-Melvin black hole spacetime
read the original abstract
We revisit the innermost stable circular orbits (ISCOs) of charged particles and study the polarized images of synchrotron radiations emitted from such orbiting hotspots on the equatorial plane in Schwarzchild-Melvin black hole spacetime. We obtain a constraint on the magnetic field to retain ISCOs for charged particles. In particular, we identify a critical value for the strength of the magnetic field $B_c$ that the circular orbits can have positive and negative angular momentums above $B_c$ while only one branch survive below $B_c$. Furthermore, we investigate and discuss the primary and secondary images of circularly orbiting charged hotspots carrying the information of polarization directions observed by distant observers.

Optical Appearance of Scalarized Kerr-Newman Black Holes with Multiple Light Rings
Scalarized Kerr-Newman black holes develop an inner photon shell that produces an additional critical curve and distinct crescent-like higher-order images unlike those in Kerr spacetime.

Numerical backward ray-tracing shows that the inner shadow size shrinks with the Gauss-Bonnet coupling while polarization direction near the shadow and photon ring shifts noticeably, and combining both observables yie...
