The June 24 meeting of the RASC Mississauga Centre will feature a talk on Galaxies
Talk Title: Two Galaxies to rule them all
Speaker: George Conidis, PhD Candidate in Physics & Astronomy, York University
Our observable Universe hosts hundreds of billions of galaxies distributed unevenly in a sponge-like configuration known as the Cosmic Web. The web can be classified into four distinct groups: voids (empty regions with no/few galaxies), walls/sheets, filaments, and nodes/clusters. These structures are seeded to grow from physical processes at the earliest times in the Universe. Thus, internal to each void, sheet, filament, and node, there is embedded information about how the adolescent Universe behaved. One of the primordial signatures embedded in large scale structure is the organization of a member galaxy's orientation to their host Cosmic Web structure. Our host galaxy, the Milky Way, lives in a sheet of galaxies known as the Local Sheet. As it turns out, the Milky Way and its companion the Andromeda galaxy are the peculiar culprits behind bullying their neighbours into misalignment with the sheet and theoretical predictions.
George Conidis was recently presented with the Mitacs Award for Outstanding Innovation for research that includes discovering 174 galactic neighbourhoods that mirror our own:
The meeting will be held from 8:00 to 10:00 p.m. at The University of Toronto,Mississauga Campus, in lecture hall SE2082 in the William Davis Building. The meeting is open to the public and is free.
Enter off of Mississauga Road. Park in lot 4 or the parkade, across from the fitness centre south of theDavis Building. Enter through the Fitness centre, walk up the stairs untilyou reach the main corridor then turn right. (If you need an elevator,follow the corridor to the right of the stairs, then go up to the mainfloor.) Look for the Mississauga Centre sign in front of the lecture room.
Post meeting plans: we usually continue the discussion post-meeting at a local bar – please join us!
