Carnegie Theoretical Astrophysics Center

The ObservatoriesThe Carnegie Theoretical Astrophysics Center (CTAC) is in Pasadena, California at the Observatories of the Carnegie Institution for Science. CTAC brings theorists and observers together at the cutting edge of astrophysical research. We currently consist of four scientific staff members, ten postdocs, and a number of students. We annually offer a prize CTAC Fellowship to support independent research in theoretical astrophysics, particularly in areas related to planet formation, galaxy evolution, dark matter studies, high energy astrophysics, and cosmology. Fellows  get access to our high performance computing resources (see below). In addition, CTAC features the state-of-the-art VizLab to explore novel data sets (theoretical and observational) and provide a collaborative space to explore the mysteries of the universe.
