Hello World! Here is the abstract for my Advanced Lab project-
Title: Identifying Galaxies in Filaments Around Virgo
Abstract:
Galaxies can exist in a myriad of environments throughout the universe. One major difference between these environments is the density of the galactic population. Observations have shown that galaxies in higher density environments, such as clusters and groups, tend to have lower star formation rates than galaxies that exist by themselves in the field. Large galaxy clusters, such as the Virgo cluster, have filaments of galaxies feeding the cluster. Although they are less dense than the cluster, it is possible that these filaments are dense enough to have an impact on the galaxies that pass through them as they fall into the cluster. I will be studying three filaments around the Virgo cluster. I will identify galaxies within the selected filaments using selection criteria found in the literature, and I will cross reference them with CO observations we have taken. I will calculate star-formation rates (SFRs) for these galaxies using Galaxy Evolution Explorer (GALEX) near ultraviolet and WISE infrared observations. I will also compare these filament galaxies to their counterparts in the cluster and field with respect to star-formation rate, atomic gas, and molecular gas content as a function of stellar mass.

This background sells it all. Love it.
