Circular polarization images of Sgr A* for different magnetic field geometries
Hao Yin, Songbai Chen, Jiliang Jing
Sgr A* exhibits a persistent negative circular polarization (CP) at 230\,GHz, offering a powerful probe of the magnetic field geometry in its accretion flow. Using a stationary sem…

Bright ring features and polarization structures in Kerr-Sen black hole images illuminated by radiatively inefficient accretion flows
Hao Yin, Songbai Chen, Jiliang Jing
Using general relativistic radiative transfer (GRRT) simulations, we investigate the bright ring features and polarization structures in images of the Kerr-Sen black hole associate…
