Bridging the Gap: Observations and Theory of Star Formation Meet on Large and Small Scales

November 3-7, 2014
California Institute of Technology - Pasadena, CA 91125

Workshop Overview:

The drive to understand galaxy formation and evolution over the lifetime of the universe has justified vast space-based and ground-based facilities, as well as the development of new technologies. We have identified a multi-disciplinary important scientific topic in the area of galaxy formation and evolution that has the potential to motivate specific technological and mission requirements. Succinctly, this is by connecting the most sophisticated cosmological simulations of galaxy formation and evolution, which are able to resolve features as small as a few light years in size, with detailed observational studies of star formation in the Milky Way and nearby galaxies.

The alchemy of star formation, and the modes by which that activity couples to the broader galactic environment, occurs on small spatial scales. These scales, however, can only be traced with great sophistication in the local universe, as witnessed by observations using Spitzer, Herschel, SOFIA, and ALMA. The scales studied in the local universe are "sub-grid" for the purpose of cosmological simulations that make valiant efforts to include the physics of star formation and its feedback to the local environment. The fundamental uncertainties in how this sub-grid physics is incorporated into the larger picture are by far the greatest limitation in successfully modelling, and fundamentally understanding how galaxy formation and evolution actually works.

The purpose of this study program is to get world-class representatives of the galaxy formation, star formation, and associated detector and mission technology communities to interact with each other with sufficient focus to generate new ideas for:

  1. New observations that can be used to constrain models.
  2. Definition of tests of different models and prescriptions for star formation that will be of interest for observers.
  3. Requirements for future instruments and space missions to enable the synthesis of these research areas.

Lodging for out-of-town attendees

There are a number of hotels (6 page pdf, 56KB) that are close to the Caltech campus where we have a negotiated rate. (Please note that this negotiated rate does not guarantee you the lowest rate as there may be internet specials or AAA rates that may be better.)

Please note that with enough notice, you can reserve rooms for attendees at the Athenaeum, which has been recognized as a Platinum Club of America. Newly refurbished, it is conveniently located on the Caltech Campus. Contact Janet Seid if you would like to check the availability of this option.

Visa Requirements

For Visa requirement information and travel to the United States please visit the website of the U.S. Department of State.

Parking (for Visitors and for JPL Personnel)

For Visitors: From the Arroyo Parkway, turn right (east) on Del Mar Avenue. Proceed approximately one and a quarter miles. The Caltech campus will be on your right. Turn right (south) onto Michigan Avenue. Turn right into the outdoor parking lot and park in an unmarked spot. Buy a parking permit from the kiosks near the middle of the lot or request one ahead of time from KISS.

For JPL Personnel: JPLers may use their JPL hang tag for parking or request a special parking hangtag from the JPL parking office. Employees who do not have on-Lab parking privileges can obtain a hang tag created for this purpose from JPL parking coordinator Robert Kennedy (818-354-4586, Building 310-108B, 9/80 schedule). Please park in the outdoor parking lot located on Michigan Avenue in an unmarked spot.
