Kernel Methods for Interferometric Imaging
Dimitrios Psaltis, Feryal Ozel, Yassine Ben Zineb
Increasing the angular resolution of an interferometric array requires placing its elements at large separations. This often leads to sparse coverage and introduces challenges to r…
Advancing Black Hole Imaging with Space-Based Interferometry
Yassine Ben Zineb, Feryal Ozel, Dimitrios Psaltis
Horizon-scale imaging with the Event Horizon Telescope (EHT) has provided transformative insights into supermassive black holes but its resolution and scope are limited by ground-b…
First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resolutio…
Theoretical Foundation of Black Hole Image Reconstruction using PRIMO
Dimitrios Psaltis, Feryal Ozel, Lia Medeiros +1
A new image-reconstruction algorithm, PRIMO, applied to the interferometric data of the M87 black hole collected with the Event Horizon Telescope (EHT), resulted in an image that r…
