Number density profiles of galaxy groups and clusters in the SDSS
(Vanderbilt University. Dept. of Physics and Astronomy, 2008-04-20)
We use projected number density profiles of galaxy groups to investigate the relationship between galaxy group structure and dark matter structure within halos. We primarily study a specific model of how galaxies populate ...
Reflection and rotation for three dimensional microscopy of live cells
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-18)
Confocal scanning laser microscopy and multiphoton microscopy provide 3D data from biological specimens, but with limited z-axis precision. Multiple microscale mirrors can be used to obtain more accurate 3D data on living ...
Progress towards a quantum dot photovoltaic : nanocrystal deposition on structured titanium dioxide nanotubes
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04)
While this project did not successfully produce a working photovoltaic device, significant progress has been made in the individual components of the system. This thesis describes two of those components: fabrication of ...
Influence of patient size on dose to female breast tissue during routine computed tomography scans
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-21)
Monte Carlo methods are well suited to the evaluation of radiation transport phenomena. The scalable phantoms employed in this project permitted rapid creation of three models of similar geometry, but different body habitus. ...
Exploring the Local Association : a nearby, young kinematic stream of stars in the solar neighborhood
(Vanderbilt University. Dept. of Physics & Astronomy, 2008)
During the course of my Honors Research Project, I worked with Dr. David James to determine whether a group of target stars are members of the Local Association. I did this by reducing spectroscopic data, taken by Dr. ...
Structure function analysis of blazars AP Librae and 3c279
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-27)
Blazars AP Librae and 3c279 are analyzed for microvariability using a technique known as structure function analysis. AP Librae was observed in April of 2005 and 3c279 was observed in April of 2007. The data for AP Librae ...
