Astronomy Colloquium
Insights into Galaxies using Dynamical Modeling
Time: 3:30 pm
Place: 4421 Sterling Hall, Coffee and Cookies 3:30 pm. Talk Begins 3:45 PM
Speaker: Shravan Shetty, UW Madison Astronomy Department
Abstract: Understanding the underlying mass distribution of galaxies promises to unveil immense information about galaxies, however converting their observed two dimensional kinematics into three dimensional mass distributions is a degenerate problem. Various techniques have been used to create the detailed dynamical models of galaxies but the most general and reliable of these techniques tend to be computationally intensive even today and hence are applicable to only small number of galaxies. In recent years however, based on empirical results, the Jeans Anisotropic Models (JAM) have allowed astronomers to create detailed dynamical models for large number of galaxies. Using this technique, I present the results of my PhD thesis wherein I study the
evolution of galaxies with redshift and with environment.
