Deriving relationships between number of observed short gamma ray bursts and viewing angle

Creator:

Micallef, John T.

Abstract:

Gamma ray bursts are some of the brightest events in the entire observable universe. Since the late 1960’s, thousands of gamma ray bursts have been observed and they have been researched extensively. However, there are still many mysteries which remain unsolved. One such mystery is whether or not the viewing...

Evaluation of popcorn cultivars as resistant rotation crops to Columbia root-knot nematode : A systems approach

Creator:

Cardwell, Derek

Abstract:

This study examined the management situation for the Columbiaroot-knot nematode (Meloidogyne chitwoodi) in potato, using an approach with systems thinking and interactive meetings. The focus of current research for control of this nematode was evaluated. Control practices include crop rotation, and this study also evaluated popcorn cultivars for their potential...

Simulating Synchrotron Optical Flashes in the Reverse Shock of a Gamma Ray Burst

Creator:

Bice, Connor

Abstract:

We construct a Monte Carlo simulation in Python to calculate optical flashes at 5x10¹⁴ Hz peaking at 6x10³¹ erg s⁻¹Hz⁻¹St⁻¹ due to synchrotron radiation from the reverse shock of a gamma-ray burst’s jet. While analytical solutions to this problem exist, they rely on sweeping simplifications of what is necessarily a...

Detecting ZnS Thin Films on Si Substrates using X-Ray Diffraction

Creator:

Howorth, Benjamin

Abstract:

The goal of this research is to determine whether x-ray diffraction (XRD) is a viable method for resolving ZnS thin films on Si substrates. The samples are ZnS thin films of thickness between 50nm and 100nm, on Si substrates that are 0.5mm thick. ZnS and Si have nearly identical lattice...
