FIRST ANNOUNCEMENT The Third Workshop on Compact Steep Spectrum and GHz-Peaked Spectrum Radio Sources Kerastari, Greece May 28-31, 2002 Scientific Organizing Committee Geoff Bicknell, Wim De Vries, Carla Fanti, Roberto Fanti, Anton Koekemoer, Chris O'Dea (chair), Richard Schilizzi, Ignas Snellen, Tasso Tzioumis Scientific Rationale Recent work has identified the GHz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) radio sources as the most likely candidates for the progenitors of the large scale radio sources. The GPS and CSS sources are powerful but compact radio sources whose spectra are generally simple and convex with peaks near 1 GHz and 100 MHz respectively. The GPS sources are entirely contained within the extent of the narrow line region (< 1 kpc) while the CSS sources are contained entirely within the host galaxy (< 15 kpc). Current models for the evolution of powerful radio galaxies suggest that these sources propagate from the 10 pc to Mpc scales at roughly constant velocity through an ambient medium which declines in density while the sources decline in radio luminosity. The observed number densities of powerful radio sources as a function of linear size (from tens of parsecs to hundreds of kpc) are consistent with such a scenario. Thus, the GPS and CSS sources provide (1) probes of the ISM of the host galaxy and (2) constraints on the physics of radio galaxy evolution. Rapid progress has been made in our understanding of GPS and CSS sources though the combination of high resolution radio and optical imaging as well as IR and X-ray observations. This workshop will bring together observers from across the spectrum with theorists for an informal and stimulating exchange of ideas and results.

However, here we break with tradition by holding the workshop outside of The Netherlands. The workshop will be held in the Greek village of Kerastari, the birthplace of the LOC chair, Tasso Tzioumis. It is a tiny picturesque village, nestled in the mountains of ancient Arcadia near the town of Tripolis, in the Peloponese, the southern most part of Greece. The venue is the village hall which can accommodate a limited number of people. Workshop participation will be limited to about 50-60 persons. Participation Following the tradition of the previous workshops, participation will be by invitation only to researchers actively involved in this field. On behalf of the Scientific Organizing Committee, I would like to invite you to participate in the Workshop. If you feel that there are other researchers in this area that we may have missed, please let us know asap. How to Pre-Register Full registration, abstract submission and hotel bookings will be made in early March 2002. However, we do need to have a good estimate of likely attendance to allow us to book hotels and other facilities.
