Research projects

• The observed neutron star mass distribution as a probe of the supernova explosion mechanism - a paper with Todd Thompson and Chris Kochanek submitted to MNRAS. A short video describing key results of the paper is available on the OSU Astronomy youtube channel


• A global physical model for Cepheids - a paper with Chris Kochanek accepted to ApJ. The Cepheid light curve templates are available here. A short video describing key results of the paper is available on the OSU Astronomy youtube channel


• Effect of collective neutrino oscillations on the neutrino mechanism of core-collapse supernovae - a paper submitted to MNRAS


• The physics of the neutrino mechanism of core-collapse supernovae - a paper accepted to ApJ


• The structure of the LMC stellar halo derived using OGLE-III RR Lyr stars - a paper accepted to ApJ. See also the extinction map of the LMC including estimates of internal reddening
