December Speaker: The lives and deaths of galaxies — more than just a metaphor

Posted by as Meetings

Dr. Marcin Sawicki

7:30 PM Wednesday, December 11th, 2019 Room A104, Bob Wright Centre, UVic

Astronomers often say that galaxies were “born” soon after the Big Bang, that they “live” while they are forming new stars, and that they “die” when they turn into quiescent “red and dead” ellipticals. Surely, these biological terms are just an interesting metaphor, aren’t they? No! It turns out that there is a deep connection between the pathways galaxies take through time and those that we humans take through our life cycles. In this talk I will show you how the fates of these two very different populations – galaxies and people – are connected at an underlying, fundamental level that lets us better understand the one by understanding the other.

Dr. Marcin Sawicki is an observational astronomer who studies how galaxies form and evolve over cosmic time. He is especially fond of very large samples of galaxies that span multiple epochs, and uses data from ground-based telescopes such as CFHT, Gemini, and Subaru, and space-based observatories such as HST, Spitzer and (soon) JWST. He is Canada Research Chair in Astronomy and Professor of Astronomy and Physics at Saint Mary’s University in Halifax, and is currently on sabbatical leave visiting NRC-Herzberg in Victoria.

“What dwarfs teach us about the galaxy formation” – Azadeh Fattahi, PhD Department of Physics and Astronomy at UVic

The standard model of cosmology has been very successful in explaining the galaxy formation and structures in large scales, but observations on smaller scales raised potential questions about the validity of the model.

Bio: Azadeh was born and raised in Iran. She studied Physics for her BSc in Tehran-Iran at the Sharif University of Technology. In 2011 she moved to UVic for her MSc in Astronomy, transferring into a PhD program in 2013.
