Reference Array and Design Consideration for the next-generation Event Horizon Telescope
Sheperd S. Doeleman, John Barrett, Lindy Blackburn +26
We describe the process to design, architect, and implement a transformative enhancement of the Event Horizon Telescope (ngEHT). This program - the next-generation Event Horizon Te…
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…
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…
The ALMA Phasing System: A Beamforming Capability for Ultra-High-Resolution Science at (Sub)Millimeter Wavelengths
L. D. Matthews, G. B. Crew, S. S. Doeleman +38
The Atacama Millimeter/submillimeter Array (ALMA) Phasing Project (APP) has developed and deployed the hardware and software necessary to coherently sum the signals of individual A…
Parque Astronómico de Atacama: An ideal site for millimeter, submillimeter, and mid-infrared astronomy
Ricardo Bustos, Mónica Rubio, Angel Otárola +1
The area of Chajnantor, at more than 5000 meters altitude in northern Chile, offers unique atmospheric and operational conditions which arguably make it the best site in the world…
High-Angular-Resolution and High-Sensitivity Science Enabled by Beamformed ALMA
Vincent Fish, Walter Alef, James Anderson +66
An international consortium is presently constructing a beamformer for the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile that will be available as a facility instrum…
