======================================================================== * GC98 * "The Central Parsecs" Galactic Center Workshop to be held in Tucson, Arizona Sep. 7-11, 1998 gc98@mpifr-bonn.mpg.de http://www.mpifr-bonn.mpg.de/gc98 ======================================================================== June 3, 1998 - CALL FOR PAPERS - Dear Colleague, After a number of informal announcements, we are now pleased to formally announce the upcoming Galactic Center workshop "The Central Parsecs" to be held in Tucson, Arizona Sep. 7-11, 1998. As indicated by the title, the workshop will be dedicated to an intensive discussion of the processes seen in the innermost region of the Milky Way. The workshop will be restricted to 60 participants with ample time reserved for discussion and interaction. Proceedings will be published in the ASP Conference Series and abstracts submitted for the conference will be indexed by ADS. The workshop is jointly organized by the "Sonderforschungsbereich 328" in Heidelberg, the Steward Observatory & the Dept. of Physics of the University of Arizona, the Max-Planck-Institut fuer Radioastronomie in Bonn, and the Galactic Center Newsletter. The conference location is the Sheraton El Conquistador Resort in Tucson and the registration fee will be $250, which includes the cost for all meals, refreshments, a banquet, an excursion, and a copy of the conference proceedings. Some limited funds to sponsor younger scientists are expected to be available. More detailed and up-to-date information on the workshop, such as the motivation & format, program, location, travel, etc. is available on the conference web-site at http://www.mpifr-bonn.mpg.de/gc98 We encourage you to make frequent use of this resource and to let us know if any additional information needs to be posted to the web-site. ABSTRACTS & REGISTRATION ======================== Following the initial announcements in GCNEWS, we have already received a number of papers and solicited a few invitations in order to build a preliminary program. Further suggestions for papers are welcome and should be submitted to the SOC at gc98@mpifr-bonn.mpg.de by ***************************Abstract Deadline************************** ****************************June 30, 1998***************************** in order to guarantee full consideration.
