A Specialized Mini-Workshop at UCLA on September 19 & 20, 1996 ______________________________________________________________________ Speakers and Attendees The schedule of talks will be in the third and final mailing, to be sent out about September 10. There is still room for more talks, but please contact me before or during the first week of September in order to be scheduled. (Morris@astro.ucla.edu) Preliminary List of Tentative titles and speakers ------------------------------------------------- - Doug Roberts & Ray Plante: "Multi-field BIMA observations of the Dense gas" toward the Sickle" - Farhad Yusef-Zadeh: "The Nature of Ionized Gas in the Sickle" (tentative) - Tom Pauls: "1-cm VLA Observations of G0.18-0.04: the Spectrum of the Nonthermal Filaments" - Jan Simpson: "FIR Observations of QPS" - Cornelia Lang: "VLA H92Alpha and H115Beta Observations of the Galactic Center HII Regions: The Sickle (G0.18-0.04) and Pistol (G0.15-0.05)" - Roger Hildebrand: "An Experimentalists View of QPS Polarization" - Don Figer: "The Stellar Content of the Quintuplet, and a Global Picture of the QPS Region" - Gene Serabyn: "The Radio Arc as a Prototype for a Mechanism to Generate Nonthermal Radio Filaments near the Galactic Center" - Wayne Roberge: "Grain Alignment Mechanisms in the Sickle" - Haruyuki Okuda: "ISO Observations of the Quintuplet and Pistol" (tentative title) - Munetaka Ueno: "High resolution infrared image of the Quintuplet" - Angela Cotera: "Brackett-Gamma images and the Extinction Across the QPS Region" - Mark Morris: "The Magnetic Fields in and out of Clouds Near the QPS" a few other talks are anticipated, but are not yet committed. Other Potential Attendees: Dan Gezari, Charles Townes, Mike Werner, Steve Cowley, Luis Ho, Ian McLean, Eric Becklin _________________________________________________________________________ Description (repeated from first announcement): QPS is the Quintuplet(AFGL2004)/Pistol(G0.15-0.05)/Sickle(G0.18-0.04) complex located at the intersection of the Radio Arc with the Galactic plane. At the present time, a number of groups are studying this fascinating region with a variety of techniques, so we propose to have an informal meeting of minds about the nature of the interactions taking place there. The discussion will be focussed on four areas: 1) the nature of the stars in the Quintuplet, and their winds, 2) the physical conditions in the HII regions and in the neighboring molecular clouds, and the constraints they pose on the ionization mechanism and the source of ionization, 3) the evidence for magnetic fields and the constraints on the magnetic field geometry, both inside and outside of the dense clouds there, and 4) the mechanisms for generating the nonthermal radio filaments of the Arc. Related topics, such as the neighboring "radio arches" and the possibly associated stellar cluster can also be addressed, time permitting. ________________________________________________________________________ When and Where The meeting will take place in the Sequoia Room of the UCLA Faculty Center, located on Circle Drive East, near the Eastern edge of campus, from 9:15 to ~5 on Thursday, September 19. A continental breakfast awaits those arriving early. At the present time, we anticipate that the talks and discussion will continue through Friday morning, September 20. Parking on campus costs $5. The permit can be purchased at the parking booth located at the Hilgard and Westholme entrance to campus, immediately adjacent to the faculty center. Parking is best done in Lot #2. Accomodations A few rooms in the UCLA Guest House ($82/night) have been reserved for workshop attendees, but the supply is exhaustible, so please contact us as soon as possible if you would like us to arrange a room. We can also help with accomodations in nearby Westwood, but keep in mind that there will be some pressure on hotel space because of the beginning of UCLA's Fall Quarter the following week.
