CXC Predoctoral Fellowship Program


The Chandra X-ray Center (CXC) solicits candidates through the CXC Predoctoral Fellowship Program for research in specified areas of high energy astrophysics. The program provides opportunities for PhD students to carry out thesis research work with scientific staff members of the CXC, for a period of two to three years.

The CXC is the Science and Operations Center for the Chandra X-ray Observatory, operated for NASA by the Smithsonian Astrophysical Observatory (SAO) at the Harvard-Smithsonian Center for Astrophysics (CfA).

CXC Predoctoral Fellowships are open to students enrolled in a PhD program in astronomy, astrophysics, or related fields. Successful applicants carry out work on their doctoral thesis under the research co-supervision of a CXC staff member, in coordination with formal supervision from their home institution. The CXC co-supervisor coordinates closely with the student's formal supervisor to arrive at a research plan that will lead to a PhD thesis. A list of current CXC predoctoral fellows can be found here.

The requirements for applicants are the following:

Start Date: For the current solicitation, a start date of September 2022 is desired, although the possibility for a start earlier in the summer may be possible upon discussion with the CXC research advisor.

Compensation: Stipends for the current academic year are $41,950. In addition we provide individual or family Health Insurance and Dental Insurance. Funds may also be available for relocation, travel, and other expenses.

Predoc Research Review Committee: In order to support and evaluate the research work of each predoctoral candidate while in residence at SAO, a Predoctoral Research Review Committee (PRRC) is established for each SAO predoc consisting of three members. Each predoctoral candidate presents their work annually to their committee for review and discussion.
