New High Proper Motion Stars from the Digitized Sky Survey. Iv. Completion of the Southern Survey and 170 Additional Stars with Μ > 0.45′′yr−1.1

Completion of the SUPERBLINK proper motion survey in the southern celestial hemisphere has turned up 170 new stars with proper motion 0.45′′yr−1 < μ < 2.0′′yr−1. This fourth and final installment completes the all-sky, data-mining of the Digitized Sky Surveys for stars with large proper motions. The areas investigated in this final installment comprise 11,600 square degrees in the declination r...

Astrometry with digital sky surveys: from SDSS to LSST

Major advances in our understanding of the Universe have historically come from dramatic improvements in our ability to accurately measure astronomical quantities. The astrometric observations obtained by modern digital sky surveys are enabling unprecedentedly massive and robust studies of the kinematics of the Milky Way. For example, the astrometric data from the Sloan Digital Sky Survey (SDSS...

Large-scale Structures behind the Milky Way from Near-ir Surveys

About 25% of the optical extragalactic sky is obscured by the dust and stars of our Milky Way. Dynamically important structures might still lie hidden in this zone. Various approaches are presently being employed to uncover the galaxy distribution in the Zone of Avoidance (ZOA) but all suffer from (different) limitations and selection effects. We investigated the potential of using the DENIS NI...

An Overview of Optical Galaxy Searches and their

Dust and stars in the Milky Way create a " Zone of Avoidance " (ZOA) in the distribution of optically visible galaxies of about 25% of the sky. To reduce this gap, optical searches for partially obscured galaxies have been performed. The status of these deep searches, in particular their completeness as a function of foreground extinction are discussed. Using existing sky surveys, over 50 000 p...
