The Subparsec-scale Structure and Evolution of Centaurus A. III. A Multi-epoch Spectral and Polarimetric VLBA Study

open access: yesThe Astronomical Journal
The Centaurus A radio galaxy, due to its proximity, presents itself as one of the few systems that allow the study of relativistic jet outflows at subparsec distances from the central supermassive black holes, with high signal to noise.

Proposed satellite laser ranging and very long baseline interferometry sites for crustal dynamics investigations [PDF]

open access: yes
Recommendations are presented for a global network of 125 sites for geodetic measurements by satellite laser ranging and very long baseline interferometry. The sites were proposed on the basis of existing facilities and scientific value for investigation

The L-/C-band feed design for the DSS 14 70-meter antenna (Phobos mission) [PDF]

open access: yes
A dual-frequency (1.668 and 5.01 GHz) feed was designed for the Deep Space Station (DSS) 14 70-m antenna to support the Soviet Phobos Mission. This antenna system was capable of supporting telemetry, two-way Doppler, and very long baseline interferometry

Viscoelastic deformation near active plate boundaries [PDF]

open access: yes
Very Long Baseline Interferometry (VLBI) now has the capacity to monitor geodetic positions with precisions of a few 1 mm over continental baselines. For tectonic applications, one of the major products of the VLBI program is the determination of the ...

An accuracy assessment of Magellan Very Long Baseline Interferometry (VLBI) [PDF]

open access: yes
Very Long Baseline Interferometry (VLBI) measurements of the Magellan spacecraft's angular position and velocity were made during July through September, 1989, during the spacecraft's heliocentric flight to Venus. The purpose of this data acquisition and
