Space-based VLBI imaging can dramatically improve state-of-the-art astronomical radio-
imaging resolution by enabling significantly longer baseline distances and eliminating …

Very-long-baseline interferometry (VLBI) for high-resolution astronomical imaging requires
phase-stable frequency references at widely separated radio-telescope antennas. For the …

The very long baseline interferometry (VLBI) technique offers angular resolutions superior to
any other instruments at other wavelengths, enabling unique science applications of high …

We present the design and implementation of an automated data calibration and reduction
pipeline for very long baseline interferometric (VLBI) observations taken at millimeter …

The past decade has seen significant advances in wide-field cm-wave very long baseline
interferometry (VLBI), which is timely given the wide-area, synoptic survey-driven strategy of …

Space VLBI (Very Long Baseline Interferometry) missions enable us to extend the baseline
length beyond the diameter of the Earth and, as a result, to obtain more precise images of …

Very long baseline interferometry (VLBI) provides the highest-resolution images in
astronomy. The sharpest resolution is nominally achieved at the highest frequencies, but as …

Extension of radio interferometric baselines into space is inevitable if a diffraction-limited
angular resolution defined by the Earth diameter at a given observing wavelength limits a …

High-resolution astronomical imaging at sub-GHz radio frequencies has been available for
more than 15 years, with the VLA at 74 and 330 MHz, and the GMRT at 150, 240, 330 and …

We have defined an affordable (projected cost on the order of $100 million) advanced
Space Very Long Baseline Interferometry (VLBI) mission named ARISE (Advanced Radio …
