Seminar〝Chemical Enrichment History of Galaxies〞

Star-UBB Seminar Series:- Chemical Enrichment History of Galaxies

The star formation and chemical enrichment histories of Local Group galaxies are traditionally studied by analysing their resolved stellar populations. The integrated light of star clusters however, can be studied using ground‐based telescopes to much larger distances. The talk will discuss the first chemical composition measurement obtained using the Infra-Red(IR) spectra the speaker and her team observed with Xshooter/Very Large Telescope(VLT) for a newly discovered young stellar cluster in the central region of our galaxy as well the first detailed chemical abundances that they obtained for three star-clusters in the Large Magellanic Cloud(LMC), using integrated-light optical spectroscopic observations obtained with the Magellan Echelle spectrograph on Magellan Baade telescope.

Scientific and Technological Advanced Research- Babeș-Bolyai University(Star-UBB) Seminar Series in Gravitation, Cosmology and Astrophysics

Presently a period of rapid and intense change are being witnessed in our understanding of the gravitational force, at a rate that is quickly increasing since the important observational discoveries of the late 1990s. With the advent of new observational techniques, the emergence of important cosmological and astrophysical paradigms can be seen that lead to a deep change in our understanding of the Universe. Astronomical observations strongly suggest that at large scales the force of gravity may not behave according to standard general relativity, and that a generalization of the gravitational action, either at the geometric level, or at the matter level, may be required for a full understanding of the gravitational interaction.

The goal of the present seminar is to bring Theoretical Gravitational Physics closer to the observations and experiments, and to discuss current topics in general relativity, high-energy physics, astrophysics and cosmology.
