Opis

The ESO jIAC Workshop on Quasar Hosts was held in Puerto de la Cruz, Tenerife, from 24 to 27 September 1996 in the Conference Centre of the Ca- bildo Insular de Tenerife. The four days of the meeting were filled with fasci- nating new results and interesting discussions, and ranged from the centre of our own galaxy to some of the most distant objects known in the universe. Quasar Host studies are going through an exciting time, and are benefiting from new facilities, including the refurbished HST and the Keck, and from novel techniques, including adaptive optics and deconvolution methods. We also saw the first of hopefully many results from the ISO satellite. These re- sults were presented during the many sessions and discussed in the gardens over coffee, and on the bus during our tour of the Canaries Observatories. We would very much like to thank the secretaries of ESO and lAC, Christina Stoffer, Pamela Bristow, Monica Murphy, Judith de Araoz, and Beatriz Mederos, who we depended on for their expertise and efficiency. Our colleagues on the scientific organising committee, Phil Crane, Bob Fosbury, Marie-Helene Ulrich, Peter Shaver and Jose Rodriguez-Espinosa, deserve considerable thanks for their contributions to the programme. We must also thank the local organising committee, Fernando Cabrera- Guerra, Monica Murphy, Ismael Perez-Fournon, Ana Perez-Garcia, Luis Ramirez-Castro, and Montserrat Villar-Martin, for all their efforts in making sure things ran smoothly on the day.

These proceedings contain the papers presented at the ESO/IAC workshop on Quasar Hosts. They summarize the current state of research on the host galaxies of quasars and present new observations, including data from the Keck, HST, and ISO. Separate sections deal with direct observations of quasar hosts, the radio loud/quiet dichotomy, unification schemes, radio galaxies at high redshift, star formation and the interstellar medium in quasar hosts, and low redshift populations. These topics were covered in review talks, contributed talks, and poster presentations, all of which are included in this volume. This book is intended primarily for professional astronomers and students, including both observers and theorists.
