HSTPROMO: The Hubble Space Telescope Proper Motion Collaboration

People     Press     Videos     Papers     Reviews     Projects     Funding    

The HSTPROMO collaboration studies a set of related Hubble Space Telescope (HST) research projects, with overlapping sets of investigators, all aimed at improving our dynamical understanding of stars, clusters, and galaxies in the nearby Universe through measurement and interpretation of their proper motions (PMs).

Individual projects are pursued by traditional teams consisting of a Principal Investigator (PI) and select Co-Investigators (CoIs). HSTPROMO adds coherence to the overall effort, and provides a framework for sharing of techniques, expertise, models, and insights.

After more than 15 years of work, our collaboration has had 50 HST projects awarded in highly competitive peer-review, supported by 6.4 million dollars in NASA research funding. A total of 42 refereed papers have been completed, with many others in preparation. We are now writing papers about data from the Gaia space mission as well, and are preparing for guaranteed-time JWST projects. Our research results have been the topic of 9 press releases, a live-televised NASA press conference, 2 Astronomy Picture of the Day images, and a Gaia image of the week. It has been discussed by Nature Magazine, Scientific American, CNN TV, and many other media outlets around the world.

A brief summary of the main HSTPROMO projects and results can be found in van der Marel et al. (2014), which summarizes our work on globular clusters; young star clusters; stars and stellar streams in the Milky Way halo; Local Group galaxies, including dwarf satellite galaxies, the Magellanic Clouds, and the Andromeda galaxy; and AGN Black Hole Jets. A more extensive review of Local Group proper motion dynamics is presented in van der Marel (2014). Slides from a recent talk about some of these results can be found here.
