Computational astrophysics online course

Over the past few decades
Computers have become fast enough and storage cheap enough to make computational astrophysics a powerful tool for astronomy
Alongside telescope or spacecraft observations
Theoretical models
And laboratory experiments.

Computational astrophysics is complementary to both lab work and theory
Allowing researchers to run many simulations of the same system
Or change the parameters of an astrophysical model to check how the outcomes differ.
Computation can also be used to compare different models of a system to determine which one fits observational data best.
