A Multi-Wavelength Analysis Of Cold Evolving Interstellar Clouds, Mary Spraggs
A Multi-Wavelength Analysis Of Cold Evolving Interstellar Clouds, Mary Spraggs
Mahurin Honors College Capstone Experience/Thesis Projects
The interstellar medium (ISM) is the dynamic system of gas and dust that fills the space between the stars within galaxies. Due to its integral role in star formation and ga-lactic structure, it is important to understand how the ISM itself evolves over time, in-cluding the process of cooling and condensing required to form new stars. This work aims to constrain and better understand the physical properties of the cold ISM with sev-eral different types of data, including large surveys of neutral atomic hydrogen (HI) 21cm spectral line emission and absorption, carbon monoxide (CO) 2.6mm line emission, and multi-band infrared …

Examining Type Ia Supernova Progenitors From Local Event Rates, Schuyler Wolff
Mahurin Honors College Capstone Experience/Thesis Projects
We present the recalculation of the rates of supernovae in local, low redshift (z ≤ 0.1) from the Nearby Galaxies Supernovae Search Project (Strolger, 2003) using an improved baseline designed to maximize SNe yield. Approximately 15 additional SNe of various types and ages have been discovered from the dataset and added to the 42 SNe already detected. This sample is sufficient to obtain an accurate rate of SNe in the local universe. The rates are weighted by volume, total light, and host galaxy type. Further spectroscopic data for the progenitor galaxies of each event will allow us to compare the …
