Meet the People at the BHI
Jonathan Weintroub is an electrical engineer and scientist at the Harvard-Smithsonian Center for Astrophysics. He leads the digital signal processing group for the Submillimeter Array (SMA), an element open-skies radio interferometer located on Maunakea in Hawaii. The SMA, used as an EHT station from the early days of the EHT, operates at frequencies of 230 GHz and above, and thus demands very wideband signal processing. Dr. Weintroub led the group which designed and deployed the “SMA Wideband Astronomical ROACH2 Machine” (SWARM) a 32 GHz bandwidth correlator and VLBI phased array, which transformed the utility of the SMA when it was commissioned as the primary facility back end in 2017. Jonathan is also the lead engineer for the EHT.
