Computational Astrophysics Postdoctoral Researcher

What You Will Do

Postdocs in the CTA apply semi-analytical models, high performance multi-physics simulations, data analysis, and machine learning to solve critical problems across a wide variety of astrophysical topics. These include supernovae and kilonovae explosion mechanisms and transients, stellar evolution, gamma-ray bursts, accretion, stellar evolution, planetary physics, and cosmology. CTA works with LANL and external collaborators to tie these simulations with ground and satellite-based missions including HAWC, NuSTAR, LIGO, LISA, JWST, EHT, and ZTF. Together the CTA strives to apply the computational innovations from astrophysics to other laboratory programs including The Advanced Simulation and Computing Program, Office of Experimental Sciences, and Global Security.
