Postdoctoral Fellowship Program

The Carnegie Observatories offers several postdoctoral fellowship programs in observational and theoretical astrophysics and instrumentation. These include the Carnegie Fellowship, Carnegie Theoretical Astrophysics Center (CTAC) Fellowship, Carnegie-Princeton Fellowship, and Carnegie-Caltech Brinson Fellowship in Observational Astronomy, which are all available for the November 1, 2022 application deadline for fellowships beginning in September 2023.

Details of each fellowship program are outlined below.

All fellows are expected to pursue research topics of their choice. Fellows enjoy access to all of Carnegie’s observing facilities in Chile on the same basis as the scientific staff, including the two 6.5-meter Magellan telescopes, the 2.5-meter du Pont telescope, and the 1.0-meter Swope telescope, all at Las Campanas Observatory. In the recent past, Carnegie Fellows have generally received 3-5 nights of Magellan time per semester. Carnegie is also a full institutional member of the Sloan Digital Sky Survey V.  Scientific computing resources available include the Observatories own 'Mies' compute cluster and significant access to Caltech's HPC Center resources through our Institutional partnership. Based in Pasadena, between the Jet Propulsion Laboratory and the California Institute of Technology, the Observatories provides an exceptional research environment and access to resources for theorists, observers, and instrumentalists alike. Each fellowship provides ample support for travel, computing, and publications. A list of current and past fellows and their current positions is available here.

The Carnegie Institution strives to enable a scientifically excellent, equitable, and inclusive community, and therefore aims for diverse groups of people to collaborate and thrive at Carnegie.

If you are interested in having Carnegie host your Hubble, Jansky, NSF, or other fellowship, please contact Dr. Josh Simon. Externally funded fellows also have access to Carnegie’s observing and computing facilities described above.

Carnegie Fellowship (due Nov. 1, 2022)

This fellowship is intended to encourage long-term research in observational astrophysics and/or instrumentation. We are particularly interested in applicants who have received their Ph.D. degree within the past three years. Fellowships are awarded for two years and may be renewed for an additional third year. The successful applicant must have completed the Ph.D. requirements before assuming the fellowship. Please find further details in our job announcement at Email inquiries may be sent to Dr. Josh Simon at

Carnegie Theoretical Astrophysics Center (CTAC) Fellowship (due Nov. 1,  2022)

The CTAC fellowship is intended to encourage long-term research in theoretical astrophysics, particularly in areas related to star/galaxy/black hole formation and evolution, Milky Way dynamics and dark matter, transient explosive events, exoplanet formation and dynamics, and cosmology (see Fellows are expected to carry out an independent program of research that complements and enhances both the theoretical and observational activities at Carnegie. CTAC Fellows have full access to Carnegie's computational resources--previous fellows have utilized 1-2 million CPU hours per year. The fellowship is awarded for two years and may be renewed for an additional third year. The successful applicant must have completed the Ph.D. requirements before assuming the fellowship.

Carnegie-Princeton Fellowship (due Nov. 1, 2022)

This joint fellowship is intended for candidates whose research would benefit from the collaborators and resources available at both the Carnegie Observatories and Princeton University. The Department of Astrophysical Sciences at Princeton is a major partner in the Atacama Cosmology Telescope, the Simons Observatory, and the Large Synoptic Survey Telescope. The department is collaborating with the Japanese astronomical community on large imaging and spectroscopic surveys with the Subaru Telescope, focused on extragalactic astronomy (the Hyper Suprime-Cam survey) and planetary systems around other stars (the Charis survey). In addition, Princeton is heavily involved in planning for the Prime Focus Spectrograph Survey. The successful applicant will have the right to join all these surveys. Together with research groups in other departments in the university and the nearby Institute for Advanced Study, the department offers an unparalleled environment for research in theoretical and observational astrophysics and cosmology.

Carnegie-Caltech Brinson Fellowship in Observational Astronomy (due Nov. 1, 2022)

This new joint fellowship provides a unique opportunity for candidates who will make excellent use of the observing facilities, survey data sets, and collaborators at both Carnegie and Caltech.  Caltech is a partner in the Keck Observatory, Palomar Observatory, and Owens Valley Radio Observatory, as well as LIGO and several space missions.  The successful applicant will have standard access to the facilities of both institutions throughout the term of the fellowship.  Please find further details in our job announcement at  Please send any inquiries to Dr. Josh Simon (Observatories) at or to Prof. Lynne Hillenbrand (Caltech) at

How to Apply

Applications for all fellowships include a cover letter, curriculum vitae, bibliography, an essay describing the applicant's previous work and future research plans (up to 5 pages including references), and a one page broader impact statement articulating the applicant's past accomplishments and future plans in any of the following areas: contributions to diversity, equity, and inclusion, mentoring, service work, and outreach (see this link for more information). Only a single application is required when applying for any of the above fellowships, and the application may be submitted online using the link below. Please indicate the fellowships in which you are interested by selecting the appropriate checkboxes. Applicants must also provide the names and email addresses of three references, who will be emailed a link for electronic submission of their letters. Applications for all fellowships are due by November 1. Reference letters are due November 7.

Applicants for the Carnegie-Princeton fellowship must ALSO submit their application to Princeton via Note that three letters of reference must be submitted to BOTH Carnegie and Princeton via their respective online applications. The research plan should address how the applicant intends to use the resources and facilities available at both host institutions. Selection of the successful candidate will be made by a joint Carnegie-Princeton committee.  All applicants for the Carnegie-Princeton Fellowship will automatically be considered for all postdoctoral positions in the Astrophysical Sciences department at Princeton and for the Carnegie Fellowship at The Observatories; however, they should clearly state in the cover letter that they wish to be considered for the Carnegie-Princeton Fellowship.

Applicants for the Brinson fellowship do not need to submit a separate application to Caltech.  The cover letter and/or research statement should clearly explain how the proposed work will capitalize on the unprecedented telescope access afforded by this position.
