Time Line of Lectures:
Lecture 1: ( Saturday - 27 Shahrivar 1400 - 18 Sep 2021 )
In this lecture, we start talking about
cosmology from 1917 paper of Einstein on cosmological principle. Then we talked
about the expansion of universe and Hubble-Lemaitre law. Then we discuss about
the observables in astronomy (position in sky and spectral energy distribution).
The we talk about the photons in universe, cosmic microwave background radiation
and measurements of density parameters.
Lecture 2: ( Monday - 29 Shahrivar 1400 - 20 Sep 2021 )
In this lecture, we continue with our studies on the mainstream of thoughts that LCDM emerged from. The large scale structure, concept of correlation functions, and observables are discussed. Then we study the idea of missing matter and dark matter. Then we come up with accelerated expansion of the universe.
Lecture 3: ( Saturday - 3 Mehr 1400 - 25 Sep 2021)
In this lecture we conclude the idea of standard model of cosmology through the ideas of CMB and LSS.
* Monday 5 Mehr 1400 - 27 Sep 2021 official Holiday
Lecture 4: ( Saturday - 10 Mehr 1400 - 2 Oct 2021 )
In this lecture we study the idea of distances in cosmology, comoving, Luminosity distance and angular diameter distance. We also investigate the idea of using SNe Ia as standard candles to constrain the cosmological models.
Lecture 5: ( Monday - 12 Mehr 1400 - 4 Oct 2021 )
In this lecture we study the Boltzmann equation in FLRW universe and its consequences in distribution of matter and radiation in universe.
