Multimessenger Astronomy: Modeling Gravitational And Electromagnetic Radiation From A Stellar Binary System, Kevin Kern
Multimessenger Astronomy: Modeling Gravitational And Electromagnetic Radiation From A Stellar Binary System, Kevin Kern
Honors Theses
Our Solar System is one of roughly 100 billion other stars that make up the Milky Way Galaxy. Two-thirds of all stars are paired off, forming a gravitational bond between one another. Such systems are known as stellar binaries. Although these binaries are prevalent there is much yet to be learned about their formation, evolution, and interactions. The approach taken in this thesis is to produce simulated data representing the expected measurements that an observational astronomer would collect. Specifically, we have simulated the data from an eclipsing binary light curve, spectroscopic velocity curve, and the gravitational wave times series form …

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 …
