About Me:I am a 6th year graduate student in the Astronomy and Astrophysics department at the University of California, Santa Cruz, although I currently live in Santa Fe, NM and am affiliated with Los Alamos National Lab. I plan to complete my PhD in computational astrophysics this June, under the direction of Dr. Stan Woosley. The subject of my dissertation is the simulation of post-explosion hydrodynamics in primordial and solar metallicity supernovae, and the implications this has for the early chemical enrichment of the universe. As part of my thesis, I have used the University of Chicago's FLASH code to publish one paper on the differences in mixing between compact blue supernovae and more extensive red solar metallicity supernovae. I am currently working with a team at Lawrence Berkeley Laboratory on the development and implementation of CASTRO, a massively parallel Eulerian AMR code for the equations of compressible hydrodynamics. I have been one of the first users of the code, and have provided guidance regarding the addition and implementation of some critical features, such as the ability to expand and rescale the grid to follow shocks. I have written other parts of the code, including a routine that efficiently places refinement in the physically interesting areas of the simulation and has been adapted by other users. Using CASTRO, I have published the largest survey to date of Rayleigh-Taylor mixing in core-collapse supernovae, covering 36 zero- and low- metallicity models. In the course of preparing this paper, I developed my own pipelines for writing consistent input files, and for largely automating the analysis of the extensive amount of data produced by this survey. I currently have in preparation a three-dimensional survey of mixing in the envelopes of zero-, low-, and solar metallicity core-collapse supernovae, as well as a paper modeling the post-explosion hydrodynamics within pair instability supernovae, both using CASTRO. I am a co-author on the paper detailing the CASTRO code, which is due to be submitted near the end of January. |
