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…
Studying Black Holes on Horizon Scales with VLBI Ground Arrays
Lindy Blackburn, Sheperd Doeleman, Jason Dexter +35
High-resolution imaging of supermassive black holes is now possible, with new applications to testing general relativity and horizon-scale accretion and relativistic jet formation…
Prospects for Wideband VLBI Correlation in the Cloud
Ajay Gill, Lindy Blackburn, Arash Roshanineshat +5
This paper proposes a cloud architecture for the correlation of wide bandwidth VLBI data. Cloud correlation facilitates processing of entire experiments in parallel using flexibly…
VLBI imaging of black holes via second moment regularization
S. Issaoun, M. D. Johnson, L. Blackburn +3
The imaging fidelity of the Event Horizon Telescope (EHT) is currently determined by its sparse baseline coverage. In particular, EHT coverage is dominated by long baselines, and i…
Universal Interferometric Signatures of a Black Hole's Photon Ring
Michael D. Johnson, Alexandru Lupsasca, Andrew Strominger +14
The Event Horizon Telescope image of the supermassive black hole in the galaxy M87 is dominated by a bright, unresolved ring. General relativity predicts that embedded within this…
First M87 Event Horizon Telescope Results. II. Array and Instrumentation
The Event Horizon Telescope Collaboration
The Event Horizon Telescope (EHT) is a very long baseline interferometry (VLBI) array that comprises millimeter- and submillimeter-wavelength telescopes separated by distances comp…
rPICARD: A CASA-based Calibration Pipeline for VLBI Data
M. Janssen, C. Goddi, H. Falcke +5
Currently, HOPS and AIPS are the primary choices for the time-consuming process of (millimeter) Very Long Baseline Interferometry (VLBI) data calibration. However, for a full end-t…
EHT-HOPS pipeline for millimeter VLBI data reduction
Lindy Blackburn, Chi-kwan Chan, Geoffrey B. Crew +12
We present the design and implementation of an automated data calibration and reduction pipeline for very-long-baseline interferometric (VLBI) observations taken at millimeter wave…
rPICARD: A CASA-based Calibration Pipeline for VLBI Data. Calibration and imaging of 7 mm VLBA observations of the AGN jet in M87
Michael Janssen, Ciriaco Goddi, Ilse M. van Bemmel +8
(Abridged) The CASA software suite, can now reduce very long baseline interferometry (VLBI) data with the recent addition of a fringe fitter. Here, we present the Radboud PIpeline…
Calibration of ALMA as a phased array: ALMA observations during the 2017 VLBI campaign
Ciriaco Goddi, Ivan Marti-Vidal, Hugo Messias +14
We present a detailed description of the special procedures for calibration and quality assurance of Atacama Large Millimeter/submillimeter Array (ALMA) observations in Very Long B…
