EVENT HORIZON TELESCOPE

The Event Horizon Telescope (EHT) has recently published the first images of black holes at the center of the galaxy M87 as well as our own!  To compare with these observations, we theorists perform general relativistic magnetohydrodynamic (GRMHD) simulations, followed by general relativistic radiative transfer (GRRT) to make model images.  I joined the EHT collaboration in 2020, and have been heavily involved in extracting science from these images ever since!

For example, I performed a study of Faraday rotation in models of M87's black hole.  This video is a model of M87's black hole, color-coded by rotation measure (RM), an observable which traces Faraday rotation.  We found significant time variability and spatial non-uniformity, motivating continued monitoring of this source!
