About

Ranjani Srinivasan is the lead digital backend (DBE) engineer for the Next Generation Event Horizon Telescope (ngEHT). The ngEHT project aims to make movies of black holes and study fundamental physics relating to Einstein’s theory of General Relativity among other objectives. She is designing part of the next generation instrumentation that will allow the astronomers to achieve the above goals. This instrument will process more signal bandwidth than before using very high speed analog to digital converters, and cutting edge digital electronics such as field programmable gate arrays (FPGA). Prior to joining SAO, she worked on the Submillimeter Array, the Y.T. Lee array and the Greenland Telescope.

Telescopes and Instruments

Event Horizon Telescope (EHT)

Black holes are found in the centers of most galaxies, where they can influence star formation and the distribution of atoms in the environment surrounding them. However, direct observation of a black hole is difficult because it is so small relative to their masses. Founded by Shep Doeleman at the Center for Astrophysics | Harvard & Smithsonian, the Event Horizon Telescope (EHT) captured the first image ever taken of a black hole: specifically, the ring of light produced by matter just as it falls into the black hole at the center of the nearby galaxy M87. The EHT is a virtual observatory consisting of telescopes spanning the planet, from Greenland to the South Pole. The international collaboration operating the EHT includes observatories affiliated with the Center for Astrophysics: the CfA’s Submillimeter Array (SMA) and the Greenland Telescope.

The Submillimeter Array - Maunakea, HI

Located near the summit of Maunakea on the Big Island of Hawaii, the Submillimeter Array (SMA) is one of the flagship observatories of the Center for Astrophysics | Harvard & Smithsonian. The observatory consists of eight radio dishes working together as one telescope, giving astronomers a window on a wide range of astronomical objects and phenomena: planets and comets in our own Solar System; the birth of stars and planets; and the supermassive black holes hidden at the centers of the Milky Way and other galaxies. The SMA is operated jointly by the CfA and the Academia Sinica in Taiwan.
