Polarization Signatures of Sgr A* with Tilted Hybrid Magnetic Fields
Yushu Feng, Hao Yin, Songbai Chen +1
The magnetic field geometry in the near-horizon region is very important in shaping polarimetric signatures of black hole images. With a hybrid magnetic field consisting of an axis…

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…
