- Black-hole (BH) images from my BHOSS radiative-transfer code were used within interferometric-reconstruction pipelines to isolate the M87* photon ring and place constraints on the BH mass. BHOSS was one of 3 radiative-transfer codes used, generating >10^5 synthetic M87* images in the EHT simulation library: ~50% of all images. Within Imaging Team 3 at Harvard, Younsi helped produce the first images of M87*. He provided GRMHD simulations using the BHAC code (whichheI co-developed), provided model-fit data, investigating different plasma conditions and GRMHD BH parameters, helped write manuscripts, and provided input on connecting ring properties with Einstein's general-relativity and testing gravity.
