Molecular diagnostics of dense regions in nearby galaxies

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

This region is crucial because it's where stars are born and later, where they release materials back into space after their life cycle ends.The study focuses on understanding how different gases behave in the ISM and how they can tell us about the activities happening in a galaxy, like star formation or the influence of black holes. By examining specific molecules like HCN and HCO+, we can detect where black holes are affecting the ISM. Also, by studying variations in these molecules, we gain insights into the ongoing chemical changes and processes that drive the evolution of galaxies.Using advanced tools and techniques, this thesis provides a detailed look at these molecular interactions, helping to distinguish between areas in space influenced by different cosmic activities. This approach offers a new way of observing and understanding the intricate dynamics of galaxies.
