Mount Wilson Observatory is operated by the Mount Wilson Institute under an agreement with the Carnegie Institution of Washington. The Observatory occupies lands belonging to the USDA Forest Service set aside under a long-term leasehold agreement between CIW and the USDA Forest Service. The Observatory subscribes to the USDA non-discrimination policy as expressed here.

The Michelson Interferometry Prize

The Michelson Prize for Contributions to Astronomical Optical Interferometry is jointly sponsored by Commission 54 of the International Astronomical Union and the Mount Wilson Institute (MWI). The purpose of the Michelson Prize is to provide recognition within the interferometry community, as well as in the broader science community, of scientific research programs and results from the rapidly growing field of optical interferometry, and to assist the Mount Wilson Institute and the IAU Commission with engaging the community in promoting the future of optical interferometry. MWI is a non-profit corporation that operates the Mount Wilson Observatory (MWO) under an agreement with the Carnegie Institution of Washington. MWO is a world-renowned historical site in the development of optical interferometry and continues to play a significant modern role in the field.

Description of the Michelson Prize – The award recognizes outstanding achievement in the scientific research and facility areas of optical interferometry. The Prize may be given for scientific discoveries with applied optical interferometry, for guiding student research, for support of research operations including observatory management, and for related public service. The Prize may have either of two formats:

  • The Michelson Lifetime Contributions Prize recognizes a substantial history of contributions and international leadership as evidenced by one or more of: publications, advancement of knowledge, reputation, procurement and management of resources, and accomplishments of former students. The award consists of a certificate with a statement of the contributions and their significance.

  • The Michelson Investigator Prize recognizes recent, specific contributions, judged of exceptional merit or impact by such evidence as intensive follow-up activity, high citation rate, focus in conferences, or strong media interest. The award consists of a certificate with a statement of the contributions and their significance and a cash prize in an amount determined by the sponsor.
Nomination Process – A complete nomination must include the nominating letter, which provides supporting evidence as well as indicates whether the nomination is for the Investigator or Lifetime Achievement award, two letters of endorsement, a full curriculum vitae of the nominee and a statement that the nominee is aware of and approves of the nomination. Candidates may be of any age and nationality and need not be members of the IAU. All materials should be submitted by email to the Secretary of IAU Commission 54 no later than June 1, 2010.

Please note that Commission 54 is also co-sponsoring the Fizeau Prize with the Observatoire de la Côte d'Azur to recognize technical and theoretical progress in optical interferometry.
