An Investigation of Sloan Digital Sky Survey Data and Multi-Band Scaling Relations of Spiral Galaxies
(2010-09-19)
We have compiled a large sample of 3041 spiral galaxies with multi-band $gri$ photometry from the the Sloan Digital Sky Survey (SDSS) Data Release 7 archive. We compare our own extracted photometry with data products ...
The Evolution of Star Formation Activity in Cluster Galaxies Over 0.15 < z < 1.5
(2014-10-01)
In this thesis, we explore 7.5 billion years of evolution in cluster galaxy star formation activity using a sample of 11 high-redshift (1 < z < 1.5) clusters from the IRAC Shallow Cluster Survey, and 25 low-redshift (0.15 ...
Environmental Effects on Interacting Galaxy Pairs in the SDSS
(2014-09-16)
The cause of varying galaxy interaction outcomes in different environments is investigated using a sample of over 505,000 Sloan Digital Sky Survey Data Release 7 galaxies at $0.01<z<0.20$. The aim is to distinguish the ...
The SHIVir Survey: A Dynamical Catalogue of Virgo Cluster Galaxies and their Scaling Relations
By virtue of its proximity and richness, the Virgo galaxy cluster is a perfect testing ground to expand our understanding of structure formation in the Universe. Here, we present a comprehensive dynamical catalogue based ...
A Numerical Investigation of the Impact of Inclinations on the Estimates of Photometric and Dynamical Properties of Galaxies
We exploit N-body simulations (GalactICS, Illustris, NIHAO) to study the impact of inclination on the estimates on various photometric and spectroscopic quantities of galaxies such as sizes, surface brightnesses, stellar ...
The Neutral Hydrogen Content of Satellite Galaxies in the Local Volume
The properties of the satellite populations of galaxies are vital for understanding their structure and evolution in a cosmological context. Deep optical imaging surveys have revealed a host of low surface brightness (LSB) ...
Testing Photometric and Kinematic Algorithms to predict Next-Generation Telescope Survey Statistics
Reconciling the velocity function of dark matter halos in collisionless simulations with those derived observationally requires understanding how galaxies are embedded in their dark matter halos. Widefield neutral atomic ...
Evolving Galactic Dynamos and Fits to the Reversing Rotation Measures in Edge-On Galaxies
Rotation measure (RM) synthesis maps of NGC 4631 by Mora-Partiarroyo et al. (2018) show remarkable sign reversals on kpc scales as the distance from the minor axis increases in the northern halo of the galaxy. RM maps for ...
The Quenching of Cluster Galaxies
In this thesis we present two projects investigating the evolution and quenching of cluster galaxy star formation (SF) activity. Leveraging a sample of 36 galaxy clusters, we measure the level of member SF activity. Over ...
From Surface Events in DEAP-3600 to the Radial Acceleration Relation in Spiral Galaxies
One of the most outstanding mysteries in the Universe is the nature of dark matter. In this thesis, two unique projects that focus on understanding dark matter are presented. First, Machine Learning is used to detect ...
