Prospects for submillimeter VLBI of black hole photon rings with a stratospheric balloon-borne telescope
Mayukh Bagchi, Dominic W. Pesce, Felix M. Thiel +2
Submillimeter very long baseline interferometry (VLBI) achieves higher angular resolution and probes more optically thin emission near supermassive black holes, with less interstel…
Studying the Near-horizon Jet of M87 using Millimeter Balloon-borne VLBI stations
Felix M. Thiel, Dominic W. Pesce, Mayukh Bagchi +2
In this paper we present synthetic Very Long Baseline Interferometry (VLBI) observations of M87 between a near-future configuration of the Event Horizon Telescope (EHT) and one or…
The Balloon-borne VLBI Experiment (BVEX) Radio Telescope and Position Tracking System
Felix M. Thiel, Mayukh Bagchi, Laura M. Fissel +17
Very Long Baseline Interferometry (VLBI) is a technique in radio astronomy that vastly increases the diffraction limited angular resolution of radio observations by correlating sim…
An RFSoC-based Backend and Timing System for the Balloon-borne Very Long Baseline Interferometry Experiment
Mayukh Bagchi, Felix M. Thiel, Laura M. Fissel +13
We present the design and performance characterization of the digital backend and precision-timing system for the Balloon-borne Very Long Baseline Interferometry Experiment (BVEX),…
