October 21, 2020 Program Meeting

Speaker: Mia de Los Reyes

Topic: The Loneliest Galaxies in the Universe

Most of the matter in the universe is located in long and thin structures called “cosmic filaments” that stretch across the universe in web-like formations. However, some galaxies live in the much emptier spaces between cosmic filaments, called cosmic voids. By comparing the chemical makeup of void galaxies and filament galaxies, we can learn about how galaxies’ environments shape their formation and evolution.
