Towards direct imaging and orbital parameter estimation of supermassive black hole binaries with spaceborne VLBI
B. Hudson, L. I. Gurvits, E. Mooij +2
Direct observation of the orbital motion of a sub-parsec supermassive black hole binary (SMBHB) would provide the first conclusive electromagnetic proof of such systems existing. W…

Toward Optimisation of a Sub-Terahertz Spaceborne VLBI Mission
Ben Hudson, Leonid I. Gurvits, Daniel Palumbo +2
Very Long Baseline Interferometry (VLBI) provides the finest angular resolution of all astronomical observation techniques. However, observations with Earth-based instruments are a…
