NuAncestor: an artificial satellite-borne star for accurate frequency calibration of ground-based EPRV spectrographs
F. Pepe, M. Bugatti, A. Baur +17
The accuracy of state-of-the-art Extreme Precision Radial Velocity (EPRV) spectrographs depends on the access to extremely precise and stable wavelength calibration sources. There…
Optimizing VGOS observations using an SNR-based scheduling approach
Matthias Schartner, Bill Petrachenko, Mike Titus +6
The geodetic and astrometric VLBI community is in the process of upgrading its existing infrastructure with VGOS. The primary objective of VGOS is to substantially boost the number…
Evaluating the feasibility of short-integration scans based on the 2022 VGOS-R&D program
Matthias Schartner, Bill Petrachenko, Mike Titus +6
In this work, we report on activities focusing on improving the observation strategy of the Very Long Baseline Interferometry (VLBI) Global Observing System (VGOS). During six dedi…
Observations of radio sources near the Sun
Oleg Titov, Sebastien Lambert, Benedikt Soja +15
Geodetic Very Long Baseline Interferometry (VLBI) data are capable of measuring the light deflection caused by the gravitational field of the Sun and large planets with high accura…
Testing General Relativity with geodetic VLBI: what profit from a single, specially designed experiment?
Oleg Titov, Anastasiia Girdiuk, Sebastien Lambert +15
Context. We highlight the capabilities of the geodetic VLBI technique to test General relativity in the classical astrometric style, i.e., measuring the deflection of light in the…
Testing of General Relativity with Geodetic VLBI
O. Titov
The geodetic VLBI technique is capable of measuring the Sun's gravity light deflection from distant radio sources around the whole sky. This light deflection is equivalent to the c…
