Experience from geodetic very long baseline interferometry observations at Onsala using a digital backend

Journal of Geodetic Science, 2015
The Onsala Space Observatory has installed a modern digital backend for geodetic and astronomical Very Long Baseline Interferometry (VLBI). This system consists of a Digital Base-Band Converter (DBBC) and a Mark 5B+ recorder.

Probing the close environment of young stellar objects with interferometry

, 2003
The study of Young Stellar Objects (YSOs) is one of the most exciting topics that can be undertaken by long baseline optical interferometry. The magnitudes of these objects are at the edge of capabilities of current optical interferometers, limiting the ...

Time-lapse Very Long Baseline Interferometry Imaging of the Close Active Binary HR 1099

The Astrophysical Journal
We report multiepoch astrometric very long baseline interferometry observations of the chromospherically active binary HR 1099 (V711 Tau, HD 22468) at six epochs over 63 days using the Very Long Baseline Array at 22.2 GHz.

Evolution of the Termination Region of the Parsec-scale Jet of 3C 84 Over the Past 20 yr

The Astrophysical Journal
We present the kinematics of the parsec-scale jet in 3C 84 from 2003 November to 2022 June observed with the Very Long Baseline Array at 43 GHz. We find that the C3 component, a bright feature at the termination region of the jet component ejected from ...
