Astro Seminar: Marla Geha: The SAGA Survey: Exploring Satellite Galaxies Around Milky Way Analogs

Marla Geha

When: Tuesday, September 29, 2020
4:00 PM - 5:00 PM Central

Where: Online

Audience: Faculty/Staff - Student - Post Docs/Docs - Graduate Students

Contact: Yas Shemirani  

Group: Physics and Astronomy Astrophysics Seminars

Category: Academic



The SAGA Survey will spectroscopically identify satellite galaxies brighter than Mr = −12.3 around one hundred Milky Way analogs at z =0.01. I will present results from SAGA Stage II, where we have more than quadrupled the sample size of Stage I, finding 127 satellites around 36 Milky Way analogs. I will present results on the quenched fraction of satellites, luminosity functions, radial distributions and more, comparing these both to the Milky Way itself and predictions from simulation.


Speaker: Marla Geha, Yale University
