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. ...
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. ...
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 ...
Data Logistics and the CMS Analysis Model
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
The Compact Muon Solenoid Experiment (CMS) at the Large Hadron
Collider (LHC) at CERN has brilliant prospects for uncovering new
information about the physical structure of our universe. Soon
physicists around the world ...
Micro Programmable Object Navigation Gadget (micro-PONG) for Studying Electroosmotic Flow in PDMS Microchannel
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
Precise control of fluid delivery in analytical devices may be achieved by harnessing electroosmotic flow (EOF) in oxidized
poly(dimethylsiloxane) microfluidic channels fabricated via soft lithography. However, the ...
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 ...
Rotation periods of the Hyades open cluster using ASAS light curves : measuring the Hyades gyro-age and benchmarking tools for gyrochronology studies with LSST
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Rotation period distributions for older open clusters are difficult to
obtain because of the general scarcity of clusters with ages greater
than 200 Myr, as well as the challenge of measuring rotation periods
for less ...
Dark radiation from particle decays during big bang nucleosynthesis
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Cosmic microwave background (CMB) observations suggest the possibility of an extra dark
radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more
ambiguous. Dark radiation from a decaying ...
A Search for Pre-Main Sequence Eclipsing Binary Stars in the Lagoon Nebula
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
We report time-series CCD I-band photometry for the pre-main-sequence cluster NGC 6530, located within the Lagoon Nebula. The data were obtained with the 4Kx4K imager on the SMARTS 1.0m telescope at CTIO on 36 nights over ...
