Best-in-class training

The Carnegie Science Observatories operates several postdoctoral fellowship programs in observational and theoretical astronomy and instrumentation. Not all fellowships are offered every year: the Carnegie Fellowship, Carnegie Theoretical Astrophysics Center (CTAC) Fellowship, Carnegie-Princeton Fellowship, Carnegie-Caltech Theory Fellowship, and Carnegie-Caltech Brinson Fellowship in Observational Astronomy are available for a November 1 application deadline, for fellowships beginning the following fall.


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 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 IV and V. Scientific computing resources available include the Carnegie Memex cluster in addition to local computing resources.

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.

Carnegie Science 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

The 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.

Heising-Simons 51 Pegasi b Fellowship

Carnegie Science is proud to be one of a prestigious group of institutions that are eligible to host Heising-Simons 51 Pegasi b Fellows. Program participants can choose to work at Carnegie Science’s Earth and Planets Laboratory, the Carnegie Science Observatories, or both. At the Observatories, fellows can work closely with observational astronomers, theoretical astrophysicists, and on-site engineers to pioneer the instruments and observing strategies that will advance the next wave of breakthroughs in exoplanet detection and characterization.

Carnegie Theoretical Astrophysics Center (CTAC) Fellowship

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. 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.

Caltech-Carnegie Brinson Fellowship in Observational Astronomy

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.

Carnegie-Caltech Theoretical Astrophysics Fellowship

This joint fellowship is intended for candidates whose research would benefit from the collaborators and resources available at both Carnegie and Caltech. The Fellow will split their time between the Carnegie Observatories in Pasadena, and Caltech's Cahill Center for Astronomy and Astrophysics. The Theory Fellow is expected to carry out original research in any area of astrophysics, either independently or in collaboration with staff, faculty or students at the host institutions. The principal selection criteria will be outstanding research accomplishments and promise of future achievement. Preference will be given to researchers working in areas in which Caltech and Carnegie have active and overlapping interests.

Brinson Prize Fellowship in Instrumentation

Not Offered in 2024

Postdoctoral fellows in our renowned instrumentation program work with astronomers and engineers to create, design, and build world-leading telescopes and exceptional instrumentation. Instrumentation breakthroughs come from individuals who have both a background in astronomy and an interest in designing and building instruments. The Carnegie Observatories is particularly interested in candidates with this combination of skills and interests who have completed their Ph.D. within the past three years.

Carnegie-Princeton Fellowship

This joint fellowship is intended for candidates whose research would benefit from the collaborators and resources available at both Carnegie and Princeton University.  The Department of Astrophysical Sciences at Princeton is a major partner in the Atacama Cosmology Telescope (ACT), the Simons Observatory, and the Rubin Observatory Legacy Survey of Space and Time. The department is collaborating with the National Astronomical Observatory of Japan to carry out deep, high-resolution, wide-area imaging and spectroscopic surveys to study galaxy evolution, cosmology, Milky Way structure, and planetary systems on the Subaru 8.2 meter telescope on Maunakea, Hawaii as part of the Hyper Suprime-Cam and Prime Focus Spectrograph surveys. The successful applicant will have the right to join the Subaru surveys, and to apply to join the ACT and Simons Observatory collaborations, for which Princeton has institutional membership.  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.
