Comparison of dynamical and kinematic reference frames via pulsar positions from timing, Gaia, and interferometric astrometry
Niu Liu, Zi Zhu, John Antoniadis +3
Pulsars are special objects whose positions can be determined independently from timing, radio interferometric, and Gaia astrometry at sub-milliarcsecond (mas) precision; thus, the…

Evaluate the ICRF3 axes stability via extragalactic source position time series
Niu Liu, Sebastien Lambert, Felicitas Arias +2
We present an updated study on assessing the axes stability of the third generation of the International Celestial Reference Frame (ICRF3) in terms of linear drift and scatter base…
