Galaxy And Mass Assembly: A Comparison Between Galaxy-Galaxy Lens Searches In Kids/Gama, Shawn Knabel, Benne Holwerda

Strong gravitational lenses are cases where a distant background galaxy is located directly behind a massive foreground galaxy, whose gravity causes the light from the background galaxy to bend around the foreground galaxy. In addition to being visually stunning, these rare events are useful laboratories for furthering our understanding of gravity and cosmology and to determine properties, such as the mass and dark matter content, of the lensing galaxies themselves. The trouble is finding enough of these strong gravitational lenses for further study. The immensity of the catalogs being collected by state-of-the-art telescopes requires equally innovative methods for interpreting that …


The Best Studied Crab In Astronomy: Searching For Variability In Vhe Emission From The Crab Nebula, Christina Bourantas, Kate Cowger, Avery Archer Oct 2019

The Best Studied Crab In Astronomy: Searching For Variability In Vhe Emission From The Crab Nebula, Christina Bourantas, Kate Cowger, Avery Archer

Annual Student Research Poster Session

The Crab Nebula is the remnant of a powerful stellar explosion first observed in 1054 AD and has been extremely well studied for decades. previous very high energy (VHE); GeV) studies have observed no variability in the nebula flux making the Crab a standard reference tool for gamma-ray telescopes. As part of the VERITAS (Very Energetic Radiation Imaging Telescope Array System) collaboration, we continue monitoring the nebula’s flux to understand the VERITAS telescopes and physical processes occurring within the nebula. We are analyzing over 80 hours of data from 2017 and 2018 from VERITAS Collaboration, developing and adding to a …


Spectral Analysis Of Stratigraphy At Eberswalde Crater, Mars, Cory Hughes May 2019

Spectral Analysis Of Stratigraphy At Eberswalde Crater, Mars, Cory Hughes

Scholars Week

We will analyze spectral characteristics of stratigraphy in the catchment and deposit at Eberswalde Crater, Mars. This crater is a frequent contender for the preferred destination of future Mars rover and human science missions in the search for evidence of life on the Red Planet.
