Drivers of Turbulence in the Neutral Interstellar Medium of Dwarf Galaxies
The cause of HI velocity dispersions in the interstellar medium (ISM) of galaxies is often attributed to star formation, but recent evidence has shown these two quantities are not connected in regions of low star formation. This lack of connection is most apparent in dwarf galaxies and the outer disks of spiral galaxies. ...
The Milky Way in SDSS and in N-body Models
In this thesis, I present a comparison between recent Sloan Digital Sky Survey (SDSS) Galactic studies and N-body simulations to aid in the interpretation of observed structural features. I investigate the origin of the Galactic thin/thick disk system and the contents of the Galactic halo by drawing comparisons to two high ...
X-ray Binary Evolution and the Connection to Star Formation in Nearby Galaxies with the Chandra Local Volume Survey
X-ray binaries, especially those with a massive stellar companion, provide a unique probe through which one can study the end-points of high-mass stellar evolution while simultaneously tracing recent star formation. In this thesis, I analyze the high-mass X-ray binary populations of five nearby galaxies using matched observations ...
Observational Constraints on Models of Rapidly Evolving Luminous Stars
Resolved stellar populations in galaxies are excellent laboratories for testing our understanding of galaxy formation, integrated colors and luminosities, supernova progenitor masses, and energy input from stellar feedback. However, the usefulness of resolved stellar populations rests on the ability to accurately model the ...
Star Formation in N-Body + SPH Simulations
The primary focus of my thesis work is to study star formation using a series of high resolution cosmological N-body Simulations. Specifically, I have studied the total stellar-to-halo mass ratio as a function of halo mass for a new sample of simulated field galaxies using fully cosmological, LCDM, high resolution SPH + N-Body ...
