Razieh Emami – Supermassive Black Holes at the Center of M87 and Milky Way: What We Learn…

The most recent resolved images of Supermassive Black Holes (SMBHs) at the center of M87 (SMBH: M87*) as well as the Milky Way (SMBH: SgrA*) by the Event Horizon Telescope Collaboration (EHTC) has opened up a very promising era of precision (supermassive) Black Hole astrophysics. Thanks to the Event Horizon Telescope, we have now a horizon-resolved image of a few Supermassive Black Holes, as well as some knowledge about the structure of the magnetic field and the accretion flow around some BHs. Inspired by this discoveries, in this talk, Dr. Emami will speak about different aspects of the recently-reported (yet) un-polarized images of SgrA*. She will then continue with the polarized image of M87* and how we could use that to get some novel information about the structure of the magnetic field as well as the accretion flow around M87*. Dr. Emami will end with some of the next questions that scientists would like to address in the Event Horizon Telescope and the next generation of the Event Horizon Telescope (the NGEHT).

Razieh Emami is a postdoc at the Center for Astrophysics. She has worked on a variety of different topics, including early universe cosmology, massive neutrinos, gravitational waves, TDES, galaxy evolution and BH physics. As a member of the Event Horizon Telescope (EHT) and its next generation (ngeht), she is currently focused on various topics relevant to the EHT, including black hole imaging, spectral analysis, model fitting and image reconstruction.
