The Department of Astronomy and Space, in cooperation with the Continuing Education Unit, organized a lecture entitled “Differences between the Physical Properties of Emerging and Ancient Galaxies” in the presence of students, researchers, and teachers from inside and outside the university.
The lecture aimed to introduce active galaxies, which are among the most mysterious galaxies in the universe, given the relationship between many of their physical properties that are not yet understood, in addition to their goal to identify the types of these galaxies and their optical spectra and the main differences between these spectra and how to calculate the physical properties related to these optical spectra, especially for emerging and old galaxies.
The lecture presented by Dr. Harith Saad Mahdi included a review of the relationships between the physical properties related to optical spectra, which is one of these relationships between supermassive black holes in the center of the galaxy and the rate of star formation, for a model of sapphire galaxies and their division, indicating that each of the four main types is divided between subspecies, as well as the study of these spectra and their properties in physics, which will help to understand the evolution of galaxies, and this course helps to understand how the universe evolves.
