 Description
 
 Applications are invited for postdoctoral research positions as Flatiron Research Fellows (FRF) at the Center for Computational Astrophysics (CCA). The CCA offers FRFs the opportunity for independent research in areas that have strong synergy with the CCA or other centers at the Flatiron Institute.
 
 The mission of the Flatiron Institute is to advance scientific knowledge through computational methods, including data analysis, theory, modeling, and simulation. It currently houses five centers, focused on computational astrophysics (CCA), biology (CCB), mathematics (CCM), neuroscience (CCN) and quantum physics (CCQ), as well as a scientific computing core (SCC) that maintains state-of-the-art computing facilities for use by Flatiron scientists. The CCA's mission is to create, develop, and disseminate computational methods, tools, and frameworks that allow scientists to build or analyze big astronomical datasets, and to use computational and statistical techniques to understand complex, multi-scale physics in astrophysical systems ranging in scales from planets to the Universe.
 
 Please see https://www.simonsfoundation.org/flatiron/center-for-computational-astrophysics/ for a full description of CCA research areas and scientific staff.
 
 Flatiron Research Fellows are expected to carry out an active research program that can be independently directed and/or involve substantial collaboration with other members of the CCA or Flatiron Institute. In addition to their own research, Fellows help build the rich scientific community at the CCA and Flatiron Institute by: participating in seminars, colloquia, and group meetings; developing their software, mathematical, and computational expertise through internal educational opportunities; and sharing their knowledge through scientific publications, presentations, and/or software releases. Flatiron Research Fellows may also have the opportunity to organize workshops and to mentor graduate and undergraduate students through the https://www.simonsfoundation.org/grant/flatiron-institute-center-for-computational-astrophysics-pre-doctoral-program-2021-689/, the https://www.gc.cuny.edu/astrophysics, the https://www.simonsfoundation.org/2021/11/08/simons-nsbp-scholars-program-2021-499/, and the https://cunyastro.org/astrocom/. FRFs are welcome to take advantage of CCA partnerships with the Simons Observatory, the Terra Hunting Experiment, Sloan Digital Sky Survey V, Gaia, HIRAX, LIGO, and the NASA SPHEREx mission. In addition, individual CCA research scientists have significant roles in a variety of collaborations and projects, including Learning the Universe, SIMBIG, Vera Rubin, Euclid, Roman, CAMELS, MESA, AstroPy, NANOGrav, LIGO, and Gaia, and would welcome FRF collaborators. Many CCA scientists have joint appointments with other neighboring institutions as well.
 
 The CCA welcomes any applicant who feels that their research program would thrive at the CCA. We have also identified a number of strategic areas where we would particularly welcome applicants' participation, listed on https://www.simonsfoundation.org/grant/flatiron-research-fellow-opportunities under the ?Strategic Areas? tab.
 
 FRF positions are generally two-year appointments that can be renewed for a third year, contingent on performance. FRFs receive a research budget and have access to the Flatiron Institute's powerful https://www.simonsfoundation.org/2021/03/04/computation-opens-new-doors-for-science/. FRFs may be eligible for subsidized housing within walking distance of the CCA. These positions will be based in our New York City offices, with anticipated start dates between late August and early October 2026.
 
 Qualifications
 
 Education
 
 * Applicants are required to have (or receive before appointment) a PhD in a related field.
 
 Related Skills & Other Requirements
 
 * Ability to do original research in astrophysics
 
 * Ability to work both independently and collaboratively
 
 * ?Ability to present research and other types of work, internally and externally
 
 * Intellectual connections to projects in which the CCA is involved (if relevant)
 
 * Expertise in technical elements of computational astrophysics research, which may include but are not limited to: algorithm and software development; application or development of computational or statistical methods; data analysis; modeling; statistics and machine learning; scientific simulation; or theoretical astrophysics.
 
 Application Instructions
 
 REQUIRED APPLICATION MATERIALS
 
 1. Curriculum Vitae that includes a bibliography (Required)
 
 2. Research statement of no more than three pages (including figures) describing the applicant's past work, proposed research program, and potential synergies with activities at CCA (Required)
 
 * We encourage applicants, as a component of their research statement, to discuss their broader impact on the field, what they expect to bring to the CCA, and what they expect to gain from being at the CCA to further their longer term goals.
 
 3. Three (3) letters of recommendation submitted confidentially by the letter writers via Interfolio prior to the application due date (Required)
 
 * If a letter or letters have been submitted as a part of your application for a standard 3-year CCA Flatiron Research Fellowship, you do not need to request additional letters for this position.
 
 4. Cover letter (optional)
 
 * The Center for Computational Astrophysics is committed to broadening the community of scientists contributing to the field of Astrophysics. We drive innovation and collaboration by recruiting scientists from a broad range of backgrounds and experiences. With this in mind, tell us who you are and what you will bring to the CCA. Applicants are invited to describe their journey into Astrophysics research in their cover
