"Chemical Evolution of Galaxies from Nuclear Astrophysics to Cosmological Structure Formation"

Benoit Côté ( Konkoly Observatory of the Hungarian Academy of Sciences)

Galactic chemical evolution (GCE) is a multidisciplinary topic that involves nuclear physics, stellar evolution, galaxy evolution, observation, and cosmology. Observations, experiments, and theories need to work together in order to build a comprehensive understanding of how the chemical elements synthesized in astronomical events are spread inside and around galaxies and recycled into new generations of stars. The purpose of GCE is to better understand the origin of the elements in the universe and to use chemical abundances to investigate how galaxies form and evolve in a cosmological context. During this talk, I will introduce the basics of GCE and present our efforts to create permanent connections between different fields of research (including nucleosynthesis and gravitational wave physics). In particular, I will present how we used our tools to investigate the possible production sites of light and heavy elements, to quantify output uncertainties and the impact of different modeling assumptions in galaxy models, and to study how structure formation (galaxy mergers) affects the chemical evolution of galaxies in the early universe.

"Long term study of the light curve of PKS 1510-089 in GeV energies"

Raj Prince (Raman Research Institute, Bengaluru )

We have analyzed data from Blazar FSRQ PKS 1510-089 collected over a period of eight years from 2008 August to 2016 December with the Fermi-LAT. We have identified the several flares of this highly variable source, studied their temporal and spectral properties in detail. Five flares and few sub-flares have been identified in our study. I will talk about these five flares in detail.
