Astrophysical Computing

First Stars

About 100 million years after the Big Bang, gas collapsed in the first mini-halos to illuminate the universe for the first time since recombination.

First Galaxies

After the formation of primordial massive stars, stars formed in aggregations that were the first galaxies in the universe.

Magnetic Fields in the Early Universe

Magnetic fields are ubiquitous in the present-day universe. How and where did the first magnetic fields form and grow?

Visualization

To explore computational data, ingenious visualization is essential.

Radiative Transfer

Radiative transfer is an inherently difficult computational problem. We attempt to tackle it in an AMR context.

Enzo

An Eulerian AMR hydrodynamical code that powers most of our calculations.

Reionization and its Observational Consequences

We use N-body and radiative transfer simulations to model the reionization of the universe on scales of hundreds of comoving megaparsecs

Useful scripts
