Abstract:
The beginning of the VLT era was marked by two major events: the VLT Official Inauguration Ceremony at Paranal on 5 March 1999, preceded by the VLT Opening Symposium on 1–4 March. ESO is indebted to Professor J.A. Music Tomicic, Rector of the Universidad Católica del Norte, for hosting this symposium. Another major event occurred on the night of 4 March: First light was achieved ahead of schedule at Kueyen, the second 8.2-m VLT unit telescope.

Abstract:
The Atacama Large Millimetre Array (ALMA) is the new name for the merger of the major millimetre array projects - the European Large Southern Array (LSA), the U.S. Millimetre Array (MMA), and possibly the Japanese Large Millimetre and Submillimetre Array (LMSA), into one global project. This will be the largest ground-based astronomy project of the next decade after VLT/VLTI, and, together with the Next Generation Space Telescope (NGST), one of the two major new facilities for world astronomy coming into operation by the end of the next decade.

FORS1 and ISAAC science verification at Antu/UT1

AA(ESO)
Abstract:
The UT1/Antu Science Verification (SV) programme with the Test Camera, which was carried out in August 1998, included one major project (the multicolour coverage of the HDF-S) plus a number of short programmes meant to address problems in a wide range of astrophysical areas. For the SV of the two instruments now attached to UT1/ Antu (FORS1 and ISAAC) the same approach was followed, giving high priority to those programmes that potentially serve a wide section of the community. The aim of this strategy was to maximise the probability success and the scientific return, while providing the best possible service to the community and pushing to the limit the capabilities of telescope and instruments. The many goals of the SV of the VLT and its instruments are extensively discussed elsewhere (Giacconi et al. 1999, A&A, 343, L1, and references therein).

Abstract:
Stellar astrophysics is today a mature science. Many of the fundamental questions have received reasonably satisfactory answers, leaving more subtle, harder and harder problems yet to be solved. A typical example of success is offered by the quantitative knowledge of stellar evolution. We have now a fairly complete understanding on how stars of all masses evolve, from the main sequence all the way to the white dwarf stage or supernova explosion. Perhaps it is not too exaggerated to say that just details remain here and there to be worked out. On the other hand,

Abstract:
At the time of this writing, ESO is embarked on the so-called first-generation VLT instrumentation plan, with eleven different instruments for as many foci of the VLT, plus four instruments for the VLTI. When this major effort is completed around 2003 - 2004, one will then be faced with the prospect of almost immediately restarting new instrumentation, as the first instruments installed will be well in the midst of their likely 10 - 12 years useful life.

Abstract:
Conducting service observing at large ground-based observatories profits from delivering standard data products to the users. The operational applications needed to quantitatively assess VLT calibration and science data are provided by the VLT Quality Control system (QC). It allows to populate and maintain the pipeline calibration database, as well as to measure and verify the quality of observations. The QC system also provides models allowing users to predict instrument performance.

Abstract:
In May 1997 ESO has organised a first workshop on writing software for the VLT and its instruments, addressing thereby the needs of various consortia and also newly recruited ESO software engineers. Since then, the important milestones of the first light for Antu (UT1) and Kueyen (UT2) and a couple of instruments have been reached, showing that specifications have been met or even exceeded. This achievement was possible also thanks to the consistent and rigorous application of software engineering methodologies, use of common software and imposing software standards. All this makes the VLT software very homogeneous and robust.

Long-term spectroscopic monitoring of pulsating B stars: a tribute to the CAT.

Abstract:
Asteroseismology is a modern term for the study of the internal structure of multiply-periodic pulsating stars. Good candidates to perform asteroseismology of massive stars are the multiperiodic B-type pulsators, i.e. the β Cep stars and the slowly pulsating B stars.

Abstract:
The authors present here a procedure written within the ESO MIDAS reduction package with the aim of deriving semi-automatically linear polarisation data from CCD images obtained with beam-splitters such as those available at the ESO 3.6-m telescope equipped with EFOSC2 or at the VLT equipped with FORS1. The method is adequate for point-like objects and was used for measuring quasar polarisation.

Abstract:
ESO’s broad objective is to provide the astronomical communities in the member states with first-class optical infrared facilities. During the past few years, major efforts were dedicated to the refurbishment and upgrading of all the telescopes at the La Silla Observatory as well as the restructuring of the Observatory in telescope and service teams.
