The University of California High-Performance AstroComputing Center (UC-HiPACC) based at the University of California at Santa Cruz (UCSC) is a consortium of nine University of California campuses and three Department of Energy laboratories (Lawrence Berkeley National Laboratory, Lawrence Livermore Laboratory and Los Alamos National Laboratory). The consortium's goal is to support and facilitate original research and education in computational astrophysics and to engage in public outreach and education. [1]
Joel R. Primack, distinguished Professor of Physics at UCSC, has directed the UC-HiPACC consortium since its inception. [2] Peter Nugent from the Lawrence Berkley National Labarotory serves as the coordinator from northern California and Michael Norman from the University of California San Diego (UCSD) serves as the coordinator from southern California. [3] The staff includes Senior Writer Trudy E. Bell, Administrator Sue Grasso, Scientific Visualization Coordinator Alex Bogert, and webmaster Steve Zaslaw. [4] The consortium is organized at UCSC under the aegis of the Santa Cruz Institute for Particle Physics (SCIPP). [5]
The UC-HiPACC consortium, which began operating [6] in January 2010, [7] supports activities that facilitate and encourage excellence, collaboration, and education in astronomy across the University of California system [8] and affiliated DOE National Laboratories. It does not directly fund research or major hardware. Instead, UC-HiPACC sponsors working groups of UC scientists from multiple campuses and labs who pursue joint projects in computational astrophysics; workshops and conferences on topics in computational astrophysics; and an annual advanced summer school on a topic in computational astrophysics.

The Virgo Consortium was founded in 1994 for Cosmological Supercomputer Simulations in response to the UK's High Performance Computing Initiative. Virgo developed rapidly into an international collaboration between a dozen scientists in the UK, Germany, Netherlands, Canada, United States and Japan.
Eris is a computer simulation of the Milky Way galaxy's physics. It was done by astrophysicists from the Institute for Theoretical Physics at the University of Zurich, Switzerland and University of California, Santa Cruz. The simulation project was undertaken at the NASA Advanced Supercomputer Division's Pleiades and the Swiss National Supercomputing Centre for nearly eight months, which would have otherwise taken 570 years in a personal computer. The Eris simulation is the first successful detailed simulation of a Milky Way like galaxy. The results of the simulation were announced in August 2011.
Computational astrophysics refers to the methods and computing tools developed and used in astrophysics research. Like computational chemistry or computational physics, it is both a specific branch of theoretical astrophysics and an interdisciplinary field relying on computer science, mathematics, and wider physics. Computational astrophysics is most often studied through an applied mathematics or astrophysics programme at PhD level.
The Institute for Computational Cosmology (ICC) is a Research Institute at Durham University, England. It was founded in November 2002 as part of the Ogden Centre for Fundamental Physics, which also includes the Institute for Particle Physics Phenomenology (IPPP). The ICC's primary mission is to advance fundamental knowledge in cosmology. Topics of active research include: the nature of dark matter and dark energy, the evolution of cosmic structure, the formation of galaxies, and the determination of fundamental parameters.
The Bolshoi simulation, a computer model of the universe run in 2010 on the Pleiades supercomputer at the NASA Ames Research Center, was the most accurate cosmological simulation to that date of the evolution of the large-scale structure of the universe. The Bolshoi simulation used the now-standard ΛCDM (Lambda-CDM) model of the universe and the WMAP five-year and seven-year cosmological parameters from NASA's Wilkinson Microwave Anisotropy Probe team. "The principal purpose of the Bolshoi simulation is to compute and model the evolution of dark matter halos, thereby rendering the invisible visible for astronomers to study, and to predict visible structure that astronomers can seek to observe." “Bolshoi” is a Russian word meaning “big.”
The Illustris project is an ongoing series of astrophysical simulations run by an international collaboration of scientists. The aim was to study the processes of galaxy formation and evolution in the universe with a comprehensive physical model. Early results were described in a number of publications following widespread press coverage. The project publicly released all data produced by the simulations in April, 2015. Key developers of the Illustris simulation have been Volker Springel and Mark Vogelsberger. The Illustris simulation framework and galaxy formation model has been used for a wide range of spin-off projects, starting with Auriga and IllustrisTNG followed by Thesan (2021), MillenniumTNG (2022) and TNG-Cluster.

The UniverseMachine is a project carrying out astrophysical supercomputer simulations of various models of possible universes, created by astronomer Peter Behroozi and his research team at the Steward Observatory and the University of Arizona. Numerous universes with different physical characteristics may be simulated in order to develop insights into the possible beginning and evolution of our universe. A major objective is to better understand the role of dark matter in the development of the universe. According to Behroozi, "On the computer, we can create many different universes and compare them to the actual one, and that lets us infer which rules lead to the one we see."
