$75,000 (one-time award for travel, subsistence, and research expenses)

Supports a promising early-career astrophysicist with funding for postdoctoral research in a new country.

Fellowship must supplement a postdoc in a country different from where the PhD or current postdoc was completed.

--- ## Description The Gruber Foundation Fellowship, administered by the International Astronomical Union (IAU) and funded by The Gruber Foundation, is awarded annually to a promising early-career astrophysicist. The fellowship provides $75,000 to support travel, subsistence, and research expenses for a postdoctoral position. Applicants must be pursuing research in theoretical, observational, or experimental astrophysics, and the fellowship is intended to facilitate international mobility by requiring the postdoctoral appointment to be in a country different from where the applicant earned their PhD or is currently completing a postdoc. The program emphasizes scientific excellence as the primary selection criterion but gives preference to applicants from countries facing difficult economic conditions. The fellowship may be held in conjunction with other awards or fellowships. --- ## Due Dates - March 2026 (Full application deadline, anticipated/projected) *All dates are projected based on the annual cycle; check the program page for updates.* --- ## Funding Amount - $75,000 (one-time award) - Covers travel, subsistence, and research expenses to supplement a postdoctoral position --- ## Eligibility - Applicants must be early-career astrophysicists: - Either in the final months of a PhD program (PhD must be completed by the fellowship start date), or - In the first year of a postdoctoral appointment - The postdoctoral position must be at an institution in a different country than where the PhD was awarded or, for second postdocs, different from the country of the current appointment - Open to candidates in theoretical, observational, or experimental astrophysics - Preference is given to applicants from countries with difficult economic conditions - The fellowship can be held alongside other fellowships or awards --- ## Application Process - Submit a full application by the anticipated deadline (March 2026) - Application materials typically include: - Curriculum vitae - Research statement or proposal - Confirmation of postdoctoral position - Letters of recommendation - Proof of PhD completion (if applicable) - Detailed instructions and requirements are provided on the [TGF Fellowship Program site](https://www.iau.org/science/grants_prizes/gruber_foundation/fellowships/) --- ## Additional Information - The award is administered by the International Astronomical Union, with funding from The Gruber Foundation and support from the American Astronomical Society. - Scientific excellence is the main selection criterion, but economic need and international mobility are also considered. --- ## External Links - [Program Announcement & Application Details](https://aas.org/posts/news/2025/01/apply-2025-gruber-foundation-fellowship) - [TGF Fellowship Program site (IAU)](https://www.iau.org/science/grants_prizes/gruber_foundation/fellowships/) - [American Astronomical Society Funding Opportunities](https://aas.org/subjects/general-funding-opportunities) --- ## Contact Information | Purpose | Contact Details | |------------------------|---------------------------------------------------| | General Inquiries | [AAS Contact Page](https://aas.org/contact) | | Email | [email protected] | | Phone | +1 202-328-2010 |
