Example Profile

Staff Scientist II
Mitchell Revalski headshot

Dr. Mitchell Revalski is currently a Staff Scientist II on the Wide Field Camera 3 team for Hubble where he leads projects on PSF modeling and staffs the DrizzlePac Help Desk. He joined STScI as a postdoctoral researcher in 2019 and is involved with studies aimed at understanding the properties of gas in and around galaxies at cosmic noon. Specifically, he utilizes deep spectroscopy and imaging obtained with HST and MUSE to investigate the mass-metallicity relationship (MZR) for low-mass galaxies in the MUSE Ultra Deep Field (MUDF). 

Previously, Dr. Revalski was an NSF graduate research fellow at Georgia State University, where he completed his dissertation focused on the properties of AGN driven outflows. He used spatially-resolved spectroscopy and imaging from Hubble, in conjunction with multi-component Cloudy photoionization models, to precisely quantify the energetic impact of narrow line region (NLR) outflows in nearby active galaxies. He has expanded this work at STScI through his HST Cycle 28 imaging program, in order to study a larger sample spanning a broader range of AGN properties. This project has provided key insights into the best practices for determining accurate ionized gas densities, masses, and outflow energetics when using spatially-resolved spectroscopy. In addition to research, Dr. Revalski is passionate about participating in outreach events that encourage students to pursue STEM-based careers, and connecting them with the resources that they need to succeed.
