Supermassive black hole binaries in the multi-messenger context of ground and spaceborne VLBI
B. Hudson, L. I. Gurvits, D. J. D'Orazio +3
Evidence of a gravitational wave background suggests the existence of a population of sub-parsec supermassive black hole binaries (SMBHBs), with characteristic angular separations…
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…
Orbit design for mitigating interstellar scattering effects in Earth-space VLBI observations of Sgr A*
Aditya Tamar, Ben Hudson, Daniel C. M. Palumbo
(abridged) The black hole Sagittarius A* (Sgr A*) is a prime target for next-generation Earth-space very-long-baseline interferometry missions such as the Black Hole Explorer (BHEX…
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…
The Black Hole Explorer: Motivation and Vision
Michael D. Johnson, Kazunori Akiyama, Rebecca Baturin +65
We present the Black Hole Explorer (BHEX), a mission that will produce the sharpest images in the history of astronomy by extending submillimeter Very-Long-Baseline Interferometry…
Effect of Earth's Oblateness on Black Hole Imaging Through Earth-Space and Space-Space VLBI
Aditya Tamar, Ben Hudson, Daniel Palumbo
Earth-based Very Long Baseline Interferometry (VLBI) has made rapid advances in imaging black holes. However, due to the limitations imposed on terrestrial VLBI by the Earth's fini…
Orbital configurations of spaceborne interferometers for studying photon rings of supermassive black holes
Ben Hudson, Leonid I. Gurvits, Maciek Wielgus +3
Recent advances in technology coupled with the progress of observational radio astronomy methods resulted in achieving a major milestone of astrophysics - a direct image of the sha…
