Preface
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.
We were very lucky to secure financial support from Direccion General
de Ensefianza Superior del Ministerio de Educacion y Cultura in addition to
the generous support of ESO, the European Southern Observatory, and lAC,
the Instituto de Astrofisica de Canarias.
We must also express our gratitude to Cabildo Insular de Tenerife, Cabildo
Insular de La Palma and Centros de Iniciativas Turisticas de La Palma y
Tenerife for their assistance.
A special word of thanks is due to Pamela Bristow for her hard work in
compiling the present volume. Without her, you wouldn't be reading this. Bob
Fosbury also deserves a special thank-you for acting as unofficial conference
photographer.
Finally we would like to thank all the people who attended the meeting
for making it such an educational and stimulating experience.
