• A Bayesian/MCMC Approach to Galaxy Modelling: NGC 6503 

      Puglielli, David (2010-01-11)
      We use Bayesian statistics and Markov chain Monte Carlo (MCMC) techniques to construct dynamical models for the spiral galaxy NGC 6503. The constraints include surface brightness profiles which display a Freeman Type II ...
    • The Neutral Hydrogen Content of Satellite Galaxies in the Local Volume 

      Karunakaran, Ananthan
      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) ...
    • The Stellar Populations and Evolution of Virgo Cluster Galaxies 

      Roediger, Joel C. (2009-08-25)
      Using a combination of optical and near-infrared photometry, we have studied both the resolved and integrated stellar populations for a sample of Virgo cluster galaxies spanning the full range of galaxian parameters. The ...
