197. The Gaia Sausage-Enceladus stream

The gravitational capture by our own Milky Way of a satellite galaxy, some 10 Gyr ago, resulted in the so-called Gaia Sausage-Enceladus stream. The merger had a major effect on our Galaxy halo, where it accounts for more than 20 per cent of the halo's stellar population, and on the disk. I summarise our present knowledge.

Abstract

The gravitational capture by our own Milky Way of a satellite galaxy, some 10 Gyr ago, resulted in the so-called Gaia Sausage-Enceladus stream. The merger had a major effect on our Galaxy halo, where it accounts for more than 20 per cent of the halo's stellar population, and on the disk. I summarise our present knowledge.
