The science case and challenges of space-borne sub-millimeter interferometry
Leonid I. Gurvits, Zsolt Paragi, Ricardo I. Amils +51
Ultra-high angular resolution in astronomy has always been an important vehicle for making fundamental discoveries. Recent results in direct imaging of the vicinity of the supermas…
Evaluation of New Submillimeter VLBI Sites for the Event Horizon Telescope
Alexander W. Raymond, Daniel Palumbo, Scott N. Paine +8
The Event Horizon Telescope (EHT) is a very long baseline interferometer built to image supermassive black holes on event-horizon scales. In this paper, we investigate candidate si…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
Closure statistics in interferometric data
Lindy Blackburn, Dominic W. Pesce, Michael D. Johnson +4
Interferometric visibilities, reflecting the complex correlations between signals recorded at antennas in an interferometric array, carry information about the angular structure of…
Extremely long baseline interferometry with Origins Space Telescope
Dominic W. Pesce, Kari Haworth, Gary J. Melnick +8
Operating 1.5 million km from Earth at the Sun-Earth L2 Lagrange point, the Origins Space Telescope equipped with a slightly modified version of its HERO heterodyne instrument coul…
Studying black holes on horizon scales with space-VLBI
Kari Haworth, Michael D. Johnson, Dominic W. Pesce +25
The Event Horizon Telescope (EHT) recently produced the first horizon-scale image of a supermassive black hole. Expanding the array to include a 3-meter space telescope operating a…
