Introduction to very-long-baseline interferometry [PDF]

open access: yesProceedings of the IEEE, 1973
Long-baseline interferometry achieves high resolution by using two or more widely separated radio telescopes and recording video signals on magnetic tapes, which are later brought together and cross-correlated.

Very-long-baseline interferometry experiments [PDF]

open access: yes1970 Antennas and Propagation Society International Symposium, 1970
VLB observations have been made at many wavelengths from 2.8 to 270 cm. The highest resolution was obtained on the Greenbank-Crimea baseline, 2.9 x 10^8 wavelengths long at 2.8 cm on which two quasars showed interference fringes.

Lorentz symmetry and Very Long Baseline Interferometry [PDF]

open access: yesPhysical Review D, 2016
Lorentz symmetry violations can be described by an effective field theory framework that contains both General Relativity and the Standard Model of particle physics called the Standard-Model extension (SME). Recently, post-fit analysis of Gravity Probe B

First Very Long Baseline Interferometry Detections at 870 μm [PDF]

open access: yesThe Astronomical Journal
The first very long baseline interferometry (VLBI) detections at 870 μ m wavelength (345 GHz frequency) are reported, achieving the highest diffraction-limited angular resolution yet obtained from the surface of the Earth and the highest-frequency ...

Inertial sensing using Very Long Baseline Atom Interferometry

open access: gold, 2023
Gravity plays a central role in our understanding of the Earth and the Universe. It is the dominant force at astronomic scales, shaping star systems and galaxies. It is also a pivotal field in the geosciences, allowing access to the physical shape of the Earth, defining height systems, and tracking mass transport, for example water in climate change ...

Probing the solar corona with very long baseline interferometry. [PDF]

open access: yesNat Commun, 2014
AbstractUnderstanding and monitoring the solar corona and solar wind is important for many applications like telecommunications or geomagnetic studies. Coronal electron density models have been derived by various techniques over the last 45 years, principally by analysing the effect of the corona on spacecraft tracking.

Very Long Baseline Interferometry with the SKA [PDF]

open access: yesProceedings of Advancing Astrophysics with the Square Kilometre Array — PoS(AASKA14), 2015
Adding VLBI capability to the SKA arrays will greatly broaden the science of the SKA, and is feasible within the current specifications. SKA-VLBI can be initially implemented by providing phased-array outputs for SKA1-MID and SKA1-SUR and using these extremely sensitive stations with other radio telescopes, and in SKA2 by realising a distributed ...
