The K-band (24 GHz) Celestial Reference Frame determined from Very Long Baseline Interferometry sessions conducted over the past 20 years
Hana Krasna, David Gordon, Aletha de Witt +1
The third realization of the International Celestial Reference Frame (ICRF3) was adopted in August 2018 and includes positions of extragalactic objects at three frequencies: 8.4 GH…
On More than Two Decades of Celestial Reference Frame VLBI Observations in the Deep South: IVS-CRDS (1995-2021)
S. Weston, A. de Witt, Hana Krasna +13
The International VLBI Service for Geodesy & Astrometry (IVS) regularly provides high-quality data to produce Earth Orientation Parameters (EOP), and for the maintenance and realiz…
Position and Proper Motion of Sagittarius A* in the ICRF3 Frame from VLBI Absolute Astrometry
David Gordon, Aletha de Witt, Christopher S. Jacobs
Sagittarius A* (Sgr A*) is a strong, compact radio source believed to be powered by a super-massive black hole at the galactic center. Extinction by dust and gas in the galactic pl…
The third realization of the International Celestial Reference Frame by very long baseline interferometry
P. Charlot, C. S. Jacobs, D. Gordon +17
A new realization of the International Celestial Reference Frame (ICRF) is presented based on the work achieved by a working group of the International Astronomical Union (IAU) man…
The ICRF-3: Status, plans, and progress on the next generation International Celestial Reference Frame
Z. Malkin, C. S. Jacobs, F. Arias +17
The goal of this presentation is to report the latest progress in creation of the next generation of VLBI-based International Celestial Reference Frame, ICRF3. Two main directions…
Astrometry of Cassini with the VLBA to Improve the Saturn Ephemeris
Dayton L. Jones, William M. Folkner, Robert A. Jacobson +4
Planetary ephemerides have been developed and improved over centuries. They are a fundamental tool for understanding solar system dynamics, and essential for planetary and small bo…
