On the most reliable value of the Galactic aberration constant
Zinovy Malkin
Galactic aberration (GA) is a small effect in proper motions of celestial objects with an amplitude of about 5 as/yr already noticeable in highly accurate astrometric observatio…
Towards a robust estimation of orientation parameters between ICRF and celestial reference frames
Zinovy Malkin
An analysis of the source position differences between VLBI-based ICRF and -CRF catalogues is a key step in assessing their systematic errors and determining their mutual ori…
On the selection of prospective sources for ICRF extension
Zinovy Malkin
Despite continuous increasing of the number of ICRF sources, their sky coverage is still not satisfactory. The goal of this study is to discuss some new considerations for extendin…
Comparison of ground-based and Gaia photometry of astrometric radio sources
Zinovy Malkin
A comparison was made between magnitudes and magnitudes obtained from ground-based observations for astrometric radio sources . The comparison showed that these magnitudes o…

Spherical Rectangular Equal-Area Grid (SREAG): Some features
Zinovy Malkin
A new method Spherical Rectangular Equal-Area Grid (SREAG) was proposed in Malkin (2019) for splitting spherical surface into equal-area rectangular cells. In this work, some more…
