“Constrained simulations from peculiar velocities”

dr Simon Pfeifer (Leibniz-Institute for Astrophysics Potsdam, Niemcy)

Streszczenie:
Constrained simulations aim to reproduce the real Universe not just in a statistical sense but also by matching the positions and properties of observed structures. I will give a broad overview of the field of constrained simulations, and in particular the methodology of the CLUES collaboration, which uses peculiar velocities of galaxies as constraints. I will show some of the achievements from recent years and discuss the next and ongoing projects.

“The old Milky Way: investigating the past of our Galaxy”

dr hab. Rodolfo Smiljanic, prof. CAMK PAN (CAMK PAN)

Streszczenie:
Our knowledge of how the Milky Way formed and evolved is experiencing an on-going revolution, thanks to the overwhelming amount of data produced by several large stellar surveys; Gaia being the most extraordinary example of this. The study of old metal-poor stars is crucial in this context, as long-lived low-mass stars keep in their atmospheres the chemical composition of the interstellar medium at the time and place of their birth. The combination of chemical abundances with stellar orbits, in large samples of metal-poor stars, is revealing the complicated history of mergers that took place in the early stages of the Milky Way. In this seminar, I will summarise on-going work that is being done in my group, with the aim of better understanding the past of the Milky Way. I will discuss how chemical differences are being used to distinguish accreted stars from those formed in situ, the precise dating of the last major merger suffered by the Milky Way, and what accreted stars can tell about the site of r-process nucleosynthesis. I will finish with some perspective for the future, mentioning new surveys and instruments that will help sustain the revolution in this field.
