How do galaxies evolve? What was the formation history of the Milky Way? How can we tell?
There are many billions of galaxies like the Milky Way in the Universe. In this sense, our galaxy is not particularly special but it is the one we know best as we can study it in much more detail than any other in the Universe. This is because we can observe the individual stars and measure for example, how old they are, their chemical composition and how they move. All these properties help us reconstruct the story of the formation of the Milky Way, and to carry out as it were, some kind of Galactic Archeology. This relatively young research field is currently booming thanks to many new instruments and surveys on the ground, but especially because of the data from the ESA space mission Gaia. Gaia is currently mapping the Milky Way in exquisite detail what is leading to a true revolution in our understanding of the Milky Way.
After an introduction to the topic, Helmi will delve into the most recent discoveries that Gaia has made possible, and outline the history of the Milky Way in the last 10 billion years. That is we will embark on a journey that takes us to when the Universe had less 1/3 of its current age, we will go back in time to the Milky Way in its youth.
