Lecturer: Dr. Biman Nath Affiliation: Raman Research Institute Abstract: Outflows from galaxies enrich the intergalactic medium and play a crucial role in the evolution of galaxies. The standard scenario of outflows from galaxies has been that of gas driven by thermal pressure of the interstellar medium which is heated by multiple supernovae. Recent observations of galactic outflows have shown that other mechanisms such as radiation pressure and cosmic rays may also be important. I will discuss some new results on the interplay between these processes, as well as the interaction of the outflowing gas with the halo gas and how it affects the nature of outflows.
