Differential VLBI astrometry yields relative positions of radio sources with sub-milliarcsecond accuracy. These high precisions can be applied to solve various astrophysical problems. In this paper I will review the progress made recently in this …

The field of astrometry, the precise measurement of the positions, distances and motions of astronomical objects, has been revolutionized in recent years. As we enter the high-precision era, it will play an increasingly important role in all areas of astronomy, astrophysics and cosmology.

The goal of this book is to present an introduction to the techniques of astrometry and to highlight several applications of those techniques to the solution of current problems of astrophysical interest.

Following the Hipparcos and Gaia missions that have measured several billions of them using global astrometry, we propose to increase astrometry precision on pointed objects using diferential astrometry in a large field in order to unravel rocky planets in habitable zones of stars in the Sun vicinity and investigate the nature of dark matter in ...
