The Largest Sturctures in the Universe & Their Influence on Galaxies | SF

Submitted by the Event Organizer

When viewed at the largest scales, the distribution of galaxies in the Universe resembles a complex, tangled web: an interconnected network of filaments of galaxies that surround vast, empty voids. Simulations and theory have established that filaments – the largest, most densely populated structures in the Universe – have formed in the billions of years after the Big Bang, and serve as conduits for transporting gas into galaxies, which they then turn into stars.

In this talk, Dr. Alpaslan will review advances in mapping out the filamentary network of the Universe using data from the Galaxy And Mass Assembly (GAMA) survey, as well as discuss some recent advances in understanding how the galaxies that live in dense filament differ from those that exist alone in isolated voids.
