Consistency and precision of very long baseline interferometry source coordinate time series
X. -X. Zhang, N. Liu, S. B. Lambert +18
Coordinate time series of extragalactic radio sources from very long baseline interferometry observations are widely used to evaluate source positional stability, select stable sou…
Comparison of multifrequency positions of extragalactic sources from global geodetic VLBI monitoring program and Gaia EDR3
Niu Liu, Sebastien Lambert, Patrick Charlot +5
We extend previous works by considering two additional radio frequencies (K band and X/Ka band) with the aim to study the frequency dependence of the source positions and its poten…
The Fundamental Reference AGN Monitoring Experiment (FRAMEx)
B. Dorland, N. Secrest, M. Johnson +6
The U.S. Naval Observatory (USNO), in collaboration with Paris Observatory (OP), is conducting the Fundamental Reference AGN Monitoring Experiment, or FRAMEx. FRAMEx will use USNO'…
VLBI20-30: a scientific roadmap for the next decade -- The future of the European VLBI Network
Tiziana Venturi, Zsolt Paragi, Michael Lindqvist +77
This white paper describes the science case for Very Long Baseline Interferometry (VLBI) and provides suggestions towards upgrade paths for the European VLBI Network (EVN). The EVN…
Gaia Data Release 2. Short-timescale variability processing and analysis
M. Roelens, L. Eyer, N. Mowlavi +13
The Gaia DR2 sample of short-timescale variable candidates results from the investigation of the first 22 months of Gaia photometry for a subsample of sources at the Gaia faint end…
Gaia Data Release 2: Photometric content and validation
D. W. Evans, M. Riello, F. De Angeli +9
Aims. We describe the photometric content of the second data release of the Gaia project (Gaia DR2) and its validation along with the quality of the data. Methods. The validation w…
