Description

In the 20th century, galaxy properties have largely been correlated to their shapes. While this works for nearby galaxies, those that are far away require a different method. In this talk, we will show how we can use ideas from chemistry and biology to develop a new method of studying properties of galaxies. Using a sample of 100 galaxies from the state-of-the-art 2.5 meter SDSS telescope, we were able to identify which galaxies are actively forming stars and which are not, even when a clear image is unobtainable. We will also show how one can identify a galaxy’s chemical composition and how that relates to its ability to form stars. Essentially, in this project, we are investigating novel methods to classify galaxies that can be used to study the properties of the nearly 200 Billion galaxies in the universe.
