Galactic Archeaology and Chemical Tagging in the Big Data Era

Prof Keith Hawkins , The University of Texas at Austin, USA

What are the processes that govern the formation evolution and assembly of galaxies, like the Milky Way, across cosmic time? This question is among the most fundamental in modern astronomy yet the answer still eludes us to this day. Our Galaxy, our home, The Milky Way, is an optimal laboratory for answering the questions of galaxy formation and assembly because it is one of the only systems to date where we can obtain detailed and precise data on the positions motions and chemical composition for billions of individual stars. In this talk, I will focus on the research I do in Galactic Archaeology, which aims to use the chemical and dynamical information In a vast number of stars in the Galaxy to understand its formation, assembly, and evolution. Specifically, I will focus on the current projects in chemical tagging and the azimuthal variations in metallically distributions of the Galactic disk. Prof. Hawkins will be based at MPIAstronomie for his visit to Heidelberg and will be available for meetings by arrangement with his hosts, Hans-Walter Rix (rix@mpia.de) and Eduardo Banados (banados@mpia.de). Those unable to attend the colloquium in person are invited to participate online through Zoom (Meeting ID: 942 0262 2849, passcode 792771) using the link: https://zoom.us/j/94202622849?pwd=dGlPQXBiUytzY1M2UE5oUDRhbzNOZz09
