Center for Computational Astrophysics The Center for Computational Astrophysics is a research institute within the Simons Foundation focused on computational methods for astrophysics, cosmology, and data-intensive astronomy. It brings together researchers from institutions such as Princeton University, Harvard University, Massachusetts Institute of Technology, Columbia University, and California Institute of Technology to develop algorithms, simulations, and software used by projects like Event Horizon Telescope, Sloan Digital Sky Survey, James Webb Space Telescope, Laser Interferometer Gravitational-Wave Observatory, and Large Synoptic Survey Telescope. The center interfaces with national laboratories including Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, and Oak Ridge National Laboratory to scale high-performance computing workflows and to support collaborations with observatories such as National Radio Astronomy Observatory and European Southern Observatory.

History

The center was founded amid computational expansions influenced by initiatives at Simons Foundation leadership and modeled after computational efforts at Institute for Advanced Study, Flatiron Institute, and Kavli Institute for Cosmological Physics. Early collaborations included personnel from University of California, Berkeley, Stanford University, Yale University, University of Chicago, University of Pennsylvania, and New York University, building on techniques developed for projects like Millennium Simulation, IllustrisTNG, Bolshoi Simulation, and ENZO. Funding and programmatic links drew on awards from foundations associated with Mark Zuckerberg-adjacent philanthropy and scientific networks connected to National Science Foundation, NASA, and European Research Council. Leadership recruited researchers with prior posts at Princeton Plasma Physics Laboratory, NASA Goddard Space Flight Center, and Space Telescope Science Institute, adopting governance practices similar to those at Perimeter Institute and Max Planck Society.

Research and Programs

Research programs span computational cosmology, computational stellar astrophysics, computational fluid dynamics, radiative transfer, and machine learning for astronomy with teams including scientists formerly from Flatiron Institute, Los Alamos National Laboratory, Argonne National Laboratory, Fermilab, and SLAC National Accelerator Laboratory. Active programs interlink with missions and collaborations such as Gaia, Kepler, TESS, Hubble Space Telescope, Chandra X-ray Observatory, Fermi Gamma-ray Space Telescope, and theoretical frameworks influenced by work from Alan Guth, Jim Peebles, Vera Rubin, Subrahmanyan Chandrasekhar, and Stephen Hawking. Software development includes contributions to community codes used by European Southern Observatory pipelines, and algorithmic research interfaces with teams at Google DeepMind, OpenAI, NVIDIA, and Intel for high-performance machine learning. Cross-disciplinary initiatives engage scholars from Columbia University Medical Center, New York Genome Center, and computational groups at Facebook AI Research for shared infrastructure and methods.

Facilities and Infrastructure

Infrastructure leverages high-performance computing clusters and cloud resources provided through partnerships with Amazon Web Services, Google Cloud Platform, and national supercomputing centers such as National Energy Research Scientific Computing Center and Argonne Leadership Computing Facility. The center coordinates storage and data management compatible with archives like Mikulski Archive for Space Telescopes, NOIRLab, Canadian Astronomy Data Centre, and European Space Agency repositories. Visualization and analysis facilities incorporate tools developed alongside teams at Carnegie Institution for Science, Space Telescope Science Institute, Jet Propulsion Laboratory, and National Optical-Infrared Astronomy Research Laboratory to support large-scale simulations, instrument pipelines for Square Kilometre Array, and real-time transient alert systems linked to Zwicky Transient Facility and Asteroid Terrestrial-impact Last Alert System.

Collaborations and Partnerships

The center maintains formal and informal partnerships with universities and consortia including University of California, Santa Cruz, University of Washington, University of Texas at Austin, University of Michigan, University of Arizona, Princeton University Observatory, Royal Observatory, Greenwich, Max Planck Institute for Astrophysics, Institut d'Astrophysique de Paris, Instituto de Astrofísica de Canarias, and Centre National de la Recherche Scientifique. International collaborations extend to projects such as Euclid, WFIRST (Nancy Grace Roman Space Telescope), SKA Organization, and the Event Horizon Telescope collaboration, drawing on expertise from groups at University of Cambridge, University of Oxford, Imperial College London, ETH Zurich, University of Tokyo, Peking University, Tsinghua University, and Australian National University. Industrial partnerships provide hardware and algorithmic support from IBM, AMD, Cray Research, and Hewlett Packard Enterprise.

Education and Outreach

Education programs include postdoctoral fellowships modeled on fellows programs at Institute for Advanced Study, summer schools akin to Les Houches Summer School, workshops similar to Cosmo Coffee, and internships connecting undergraduate students from institutions like City College of New York, Barnard College, Hunter College, and CUNY Graduate Center with researchers formerly at Princeton University and Harvard University. Outreach events are coordinated with museums and public institutions such as the American Museum of Natural History, National Air and Space Museum, Hayden Planetarium, and initiatives tied to World Science Festival and Pint of Science to communicate results from collaborations with Event Horizon Telescope, James Webb Space Telescope, and Sloan Digital Sky Survey.

Notable Projects and Contributions

The center has contributed to numerical relativity efforts used by Laser Interferometer Gravitational-Wave Observatory detections, synthetic survey pipelines for Vera C. Rubin Observatory (LSST), magnetohydrodynamic simulations used in studies by Event Horizon Telescope and Chandra X-ray Observatory, and machine-learning frameworks adopted by Sloan Digital Sky Survey and Gaia data analysis. It has produced software stacks and community tools that integrate with efforts from Astropy Project, HEASARC, CERN-adjacent computing practices, and simulation campaigns comparable to Illustris, EAGLE, and Horizon-AGN. Key personnel include scientists who previously worked at Max Planck Institute for Astrophysics, Lawrence Livermore National Laboratory, Brookhaven National Laboratory, Yale University, University of California, Santa Barbara, and Northwestern University, and the center’s outputs have been cited in results associated with laureates of awards such as the Breakthrough Prize in Fundamental Physics and Gruber Cosmology Prize.
