280528 VU PM-Astr/PM-FnNawi Stellar populations in distant galaxies (PI) (2021W)

Purpose:
In order to investigate galaxy formation and evolution from the photometric and spectroscopic data of distant galaxies, one has to understand, first of all, how the stars and their systems evolve with time due to stellar evolution and how inter stellar medium are chemically enriched with time from which next generations of stars are formed. Moreover individual stars are not resolved in distant galaxies and we should always work on the composite spectra. Given these situations, this lecture will describe how we can build the stellar population (spectral) synthesis model which takes into account stellar evolution and chemical evolution. Next we learn the basic technique how to derive various physical quantities of galaxies from the observed data. After such preparation, we will move on to real cutting-edge observational data of distant galaxies taken by world-leading facilities, such as Subaru, ALMA, and so on, and describe what we can learn from them regarding the formation and evolution of galaxies and galaxy clusters. Phenomenological models are also introduced in these analyses. Towards the end of the lecture course, future prospects on this research subject will also be addressed.

Goals:
To understand the stellar population synthesis models (including chemical evolution) as a tool of analysing observed spectra/colours/luminosities of distant galaxies. To learn how the physical quantities can be derived from the observables. To learn how the galaxies and clusters are formed and evolved over the cosmic times and across various environments based on the recent observations of distant Universe with Suabru, ALMA, and other facilities. To be motivated to conduct research on galaxies and clusters.
