We are excited to present the eighth edition of our (fully virtual) colloquium series! Here, we will celebrate the research and leadership by Indian women Astronomers and Cosmologists across the globe. Please use this zoom link to attend the talk. Abstract: The stellar discs of galaxies have been studied extensively for many years, however they represent only the tip of the iceberg. First proposed by astronomers in 1969, it is now well-established that all galaxies are embedded in diffuse gaseous haloes known as the Circumgalactic Medium (CGM). Over the last few decades, significant effort has gone into detecting and characterizing the properties of these diffuse haloes. Lying at the interface between a galaxy and its wider environment, the CGM modulates not only the accretion and ejection of material in the galaxy, but also the interaction of the galaxy with the larger-scale environment. Moreover, the CGM is a major reservoir of baryons in the Universe, and plays a key role in the star formation and evolution of galaxies. Therefore, in order to fully understand the physical processes at work within galaxies, it is crucial to have a robust understanding of the gaseous haloes surrounding them. But how do we probe this diffuse gas? How is it distributed around galaxies? What do we know about the nature of this gas so far? How are the properties of the CGM connected with that of the galaxies and the environment? This talk will address these questions, and present the results from recent works in this exciting field in astronomy.
