Energy produced by supernovae or supermassive black holes play a major role in dictating the evolution of galaxies. The produced energy is directly responsible for heating the star-forming gas in the interstellar medium or stopping the gas to reach the galaxy, thus suppressing overall star formation. The interaction between the produced energy and the interstellar medium is often mediated by bubbles and winds, such as the gamma-ray bubbles (known as the Fermi Bubbles) in our Galaxy. Understanding such processes require multi-wavelength observations and a detailed theoretical understanding of these bubbles and winds.

In the talk, I will present some of my recent works to understand how bubbles and winds produced by supernovae and supermassive black holes interact with the interstellar medium and their observational signatures. I will also present my works on the state-of-the-art numerical simulations that have been successful to discover so far unknown properties in these systems and are bringing us much closer to bridging the gap between theory and observations in the interstellar medium.

Short Biography
Dr. Kartick Chandra Sarkar completed M.Sc. (Physics) from IIT Kharagpur in 2012. He completed Ph.D. from IISc and RRI (under JAP program) in 2017. After Ph.D., he worked as a post-doctoral fellow at the Hebrew University of Jerusalem, Israel till 2022. He then moved to Tel Aviv University, Israel in September 2022 as a Research Staff. His research interest is to understand the diffuse gaseous environment of galaxies and their interaction with the galaxy itself. Recently, he has been working on creating accurate theoretical models for observations of different processes such as galactic winds and supernovae bubbles.
