Characterizing Candidate Pingo Morphology on Ceres
Burgess, Isobel (2019-07-01)NASA’s Dawn Mission has been exploring Ceres since arrival in 2015. However, recent low-altitude Dawn orbits during its second extended mission (XM2) have brought the spacecraft as low as 35 km above the surface of Ceres, ... -
Characterizing Volcanic and Impact Materials in Lunar Craters
Robbins, Gwendolyn (2022-06-30)Impact craters on the Moon are typically infilled by either impact or volcanic melt, but outside of a few previously known characteristics, identification can be complicated. Morphological and compositional characteristics ... -
Dark Matter in the Darkest Galaxies: Exploring the Structure of Low Surface Brightness Spirals
Nagarajan-Swenson, Jaya (2022-07-01)Dark matter in our universe is not evenly distributed: some galaxies are lacking it entirely, and some galaxies have it in abundance. While its existence is generally agreed on, its distribution within galaxies is hotly ... -
Hot Dust in Galaxies at 0.25 < z < 0.29
McIntyre, Isabel (2022-07-01)Thermal dust emission within galaxies is driven by heating from young, hot stars. Because of this, one way to examine star formation in a galaxy is through the distribution of starlight and hot dust light. Independent ... -
Metallicity Gradients of Low Surface Brightness Galaxies
Hands, Lindsey (2022-06-28)Low Surface Brightness (LSB) spirals reveal a gap in the current understanding of galaxy evolution and the environments that drive star formation because, despite being gas-rich, they have not converted much of their gas ... -
Predicting Olivine Composition Using Raman Spectroscopy Through Band Shift and Multivariate Analyses
Breitenfeld, Laura (2017-05-22)Olivine minerals control many of the properties of Earth’s upper mantle. Additionally, olivines affect rheology, they may store hydrogen, and they are diagnostic of crystallization temperature. Olivine’s presence in ... -
Space Telescope Observations of Warm Dust in Low Surface Brightness Galaxies
Thao, Pa Chia (2017-12-19)Blue in color, a low star formation rate, dark matter dominated, and low in metallicity, low surface brightness (LSB) galaxies questions the current understanding of galactic formation by representing an alternative to the ... -
Star Formation and AGN Feedback in the Local Universe: Combining the Radio Continuum and Integral Field Spectroscopy
Mulcahey, Celia (2021-05-25)The effect of active galactic nuclei (AGN) on their host galaxies-in particular their star formation rates (SFRs)-remains one of the key outstanding questions of galaxy evolution. Although successful cosmological models ... -
Variability of the Unresolved X-Ray Background
Post, Elizabeth (2019-02-01)The cosmic x-ray background is diffuse, uniform x-ray radiation originat- ing from outside our galaxy. Over the past several decades since its discovery, much of it has been resolved into discrete sources. However, a ...
