The first stars have blown bubbles of ionized radiation (blue) into the surrounding primordial gas (green). Shown is a frame from a supercomputer simulation, depicting the universe three hundred million years after the Big Bang. The first galaxies were assembled out of the material affected and disturbed by the feedback from the first stars. The image shows the simulation (computed on TACC's Ranger) of the impact of radiation from early stars on surrounding primordial gas in the early Universe. Green shows concentration of molecular hydrogen in the primordial gas, while blue shows regions ionized by high-energy radiation from the stars. When a star is active, the surrounding molecular hydrogen is completely destroyed, preventing further star formation. As stars die, radiation levels decline and molecular hydrogen begins to reform, possibly allowing another round of star formation.


Computational astrophysics opens new windows in the way we perceive and study the heavens. This rapidly growing new discipline in astronomy combines modern computational methods, novel hardware design, advanced algorithms, original software implementations and associated technologies to discover new phenomena, and to make predictions in astronomy, cosmology and planetary sciences.

In the journal Computational Astrophysics and Cosmology (CompAC) we unify two distinct groups of disciplines:

  • Astronomy, planetary sciences, physics and cosmology
  • Computational and information science

The combination of these disciplines leads to a wide range of topics which, from an astronomical point of view, cover all scales and a rich palette of statistics, physics and chemistry. Computing is interpreted in the broadest sense and may include hardware, algorithms, software, networking, data management, visualization, modeling, simulation, visualization, high-performance computing and data intensive computing.

CompAC publishes novel full-length research articles, letters-to-the editor, comprehensive reviews, and concise manuals describing best practices in scientific computing and software reports.

Articles submitted to CompAC should be transparent and include all technical details for reproducibility of computational results, as well as information where benchmarks of the codes used may be found. Besides providing detailed information on simulations in the main part of simulation papers, authors will be motivated to attach an appendix to their article providing relevant information on the source code used for the research described in the manuscript.
