Atmospheric Retrieval of Exoplanets: Extracting Chemical Abundances from Spectra of Exo-atmospheres

Tuesday, February 26, 2019 - 4:00pm
Prof. Kevin Heng (University of Bern)

I will review the method of atmospheric retrieval, which is a remote sensing technique borrowed from the Earth atmospheric and planetary sciences and generalised for the study of exoplanetary atmospheres.

The SAGA Project: Satellite Galaxy Populations Around Milky Way-like Galaxies

Tuesday, December 11, 2018 - 4:00pm
Prof. Marla Geha (Yale)

The properties of the Milky Way's satellite galaxies provide critical clues to how galaxies form. However, the number of Milky Way satellites and their properties do not fully agree with well-established cosmological models. The SAGA (Satellites Around Galactic Analogs) survey is a long-term prog
