Jeff Nosanov Orbital Velocity, LLC The OBLIVION Phase I study will assess the feasibility of a novel, intensity-only interferometer architecture for direct geometric measurement of a supermassive black hole’s photon ring at gigaparsec distance. We will use Hanbury Brown–Twiss intensity correlations at 1 cm wavelength, flying two identical spacecraft in a 1.1 AU heliocentric orbit trailing […]
