Seminar 2: The dynamics of FRW universe in scalar-Tensor-Vector gravity

Abstract 1: Today, radio astronomy is one of the best methods for observing the universe. A wide range of topics, such as star and planet formation, galaxy formation and evolution and interstellar and intergalactic medium can be ideally studied using these radio data. In September 2023,IAU/I-HOW Radio Astronomy was held at Erciyes University, Kayseri, Türkiye. One of the objectives of this Workshop was to prepare young researchers to learn how to analyse radio data from radio telescopes such as ALMA and VLA. In our upcoming talk, I will discuss radio astronomy. I am going to talk about the introduction of radio telescopes and analyzing radio data. This talk will be a brief report on the topics covered in the I_HOW/IAU radio astronomy workshop. 

Abstract 2: The Scalar-Tensor-Vector-Gravity (STVG), also known as MOG (Modified Gravity), has been proposed as a solution to the dark matter problem. In this talk, a gauge-invariant theory for MOG will be introduced through a symmetry-breaking mechanism at low temperatures, where gravitational attraction is governed by an effective gravitational constant. The modified Friedmann equation and scale factor evolution for this theory will be discussed. Finally, it will be mentioned that this theory has the potential to alter the dynamics of the early and late Universe.
