Investigating young radio jets through spatially resolved simulations and observations
Dr. Dipanjan Mukherjee
Date & Time :
Relativistic jets from AGNs are an important driver of feedback in galaxies with an active black hole. They impact the nearby environment over different physical scales during their lifetime, with varying effects. They first interact with the host galaxy's ISM before breaking out to larger scales, significantly affecting the galaxy's morphology and evolution. I shall present the results of our recent 3D relativistic magneto-hydrodynamic simulations, performed on scales of several kpcs, of AGN jets interacting with the ambient ISM and CGM. The young relativistic jets initially couple strongly with the turbulent ISM, before breaking out to larger scales. Such high-resolution zoom-in simulations are ideal for comparing the theoretical simulations with spatially resolved observations of such jet-ISM interactions. I will present the expected observable features predicted from our simulations for different emission mechanisms such as photo-ionization from the AGN, emission from shocked gas, and non-thermal synchrotron emission and how they compare with some observed radio-loud sources.
About Speaker :
Prof. Mukherjee is currently an assistant professor at IUCAA since 2019. Prior to that, he carried out several postdocs, first at ANU, Australia between 2014-2017, then at Torino, Piemonte, Italy between 2017-2019. He obtained his Ph.D. in 2014 from IUCAA. His research interests are on the topics of high-energy astrophysics and simulations of astrophysical fluids over a broad range of scenarios. This invited seminar is a part of the activities commemorating "75 years of India's Independence: Azadi ka Amrit Mahotsav" at ARIES.
