RASC Vancouver Monthly Meeting Sept 14 2023

Join us for our monthly meeting. All of our monthly meetings are free and open to the public.

Location: Simon Fraser University Burnaby Room AQ3159

Topic: Gas Angular Momentum and Galaxy Quenching in the IllustrisTNG Simulation

Speaker: Marcus Cowan

Bio: I’m an undergraduate mathematical physics student at Simon Fraser University. This summer I’ve been working as a research assistant with Dr. Joanna Woo to study the evolution of galaxies in the IllustrisTNG cosmological simulation. My passion for astronomy has grown through my work, and I am excited to continue my career in the field going forward.

Abstract: The shape of a galaxy is related to galaxy quenching, which is when a galaxy shuts down its star-formation. In IllustrisTNG, a simulation of the universe that spans from the Big-Bang to modern day, the angular momentum of gas falling towards a galaxy is strongly related to the future shape of the galaxy. In other words, whether gas is spinning around a galaxy or not as it approaches plays a key role in that galaxy’s evolution. By studying the relationship between a galaxy’s location in the cosmic web and the angular momentum of its infalling gas, and how that angular momentum affects the galaxy, we can better understand galaxy evolution and quenching.

About our Events:

All RASC lectures and observing events are open to the public, family friendly, and there is no charge for admission. Our organization is run entirely by volunteers who love astronomy and astrophysics. Whether you’re a complete beginner, a seasoned astronomer, or you hope to work for NASA some day, anyone fascinated by space exploration is welcome and will enjoy our events
