Abstract
The next-generation Event Horizon Telescope (ngEHT) will be a transformative upgrade to the Event Horizon Telescope (EHT), capable of making real-time and time-lapse movies of supermassive black holes on event horizon scales. These movies will resolve complex structure and dynamics in the immediate vicinity of the event horizon, bringing into focus not just the persistent strong-field gravity features predicted by General Relativity (GR), but details of active accretion and relativistic jet-launching that drive large scale structure in the Universe. This effort builds upon recent results by the EHT: the first image of M87’s supermassive black hole and its magnetic field structure, as well as resolved images of Sgr A*, the central black hole at the heart of the Milky Way.

Dom Pesce studies the supermassive black holes (SMBHs) in the centers of galaxies, primarily using very long baseline interferometry (VLBI) observations. Dom is a member of the Event Horizon Telescope (EHT) and next-generation EHT (ngEHT) collaborations, where he works to develop techniques for modeling and imaging the horizon-scale emission from the sky's largest SMBHs. He is also a member of the Megamaser Cosmology Project (MCP), which uses VLBI observations of water masers in orbit around SMBHs to measure distances to the objects and thereby constrain the Hubble constant. His work modeling MCP and (ng)EHT data has led him to develop a deeper interest in VLBI as a measurement process, seeking to produce realistic physical models of the interferometric instruments and to acquire a deeper understanding of the nature and statistical properties of VLBI data products.
