A group of astronomers has published a new paper detailing the mergers of smaller galxies with our milky way galaxy.
The Max Planck Institute for astronomy in Heidelberg provide a landing page for the results of this work and they also share a nice video, which visualizes the mergers and the objects belonging to them.


The work is using Gaia astrometry data and identified groups of objects in our milky way as remnants of small galaxies, which were swallowed by our milky way galaxy.
The astronomers identified six mergers in the past of our galaxy and provide details, which known objects (globular cluster, stellar streams, satellite galaxies) came with which merger.
They identified specifically one group with M13, M92, M30, M56 and others as coming from one merger. In the paper they provide more details of the objects they studied.

I found this very interesting and fascinating so I decided to share it with the Astrobin community here
