A sub-kiloparsec scale view of star formation in M31
This dissertation examines the properties of star formation in the nearest large Milky Way- like galaxy, the Andromeda Galaxy (M31). Using resolved star data from the Hubble Space Telescope obtained as part of the Panchromatic Hubble Andromeda Treasury (PHAT), I model the optical color-magnitude diagrams (CMDs) of > 9000 ...
Resolved Stars' Insights into Galaxy Physics
The history of a galaxy is encoded in its individual stars, and resolved stellar populations in nearby galaxies provide a wealth of information about star formation history (SFH), its relation to the interstellar medium, and galactic dynamics/structures. Using the power of resolved stars, imaged in multiple wavelengths by the ...
Building galaxy models with self-consistent prescriptions for stellar and nebular emission
A galaxy's spectrum is the sum of light emitted by stars and gas, modulated by intervening dust. Translating between the observed flux from galaxies and meaningful astrophysical quantities relies on ``stellar population synthesis'' (SPS) models. These models include descriptions for the light produced by stars and dust in ...
