This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).
How a massive star ends its life depends upon how that life has been lived - the rotation, mass and composition it was born with, mass loss and exchange, and the complex convective and nuclear burning episodes it experienced along the way.
Precision tests of cosmology using gravitational waves will only be possible with improvements to detector sensitivity.
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
