Abstract:
MIDI, the first scientific instrument for the VLTI, has been offered to the community since the beginning of the observing period P73. In this article, we present a number of different software tools that are available for the preparation of observations, the processing of MIDI data in real-time during observing, the pipeline reduction of data at the completion of observations and the distribution of these data.

Abstract:
The scientific role of La Silla beyond 2006 was assessed by a working group composed of members of the STC, of the UC and of ESO, and chaired by Andrea Cimatti. Their “La Silla 2006+” report is available through the ESO web (www.eso.org). The main conclusion of the report is that “…. the La Silla observatory will still be a crucial component of the ESO facilities and will be a fundamental ESO component to perform world-class scientific research for European astronomers”. The report recommends that La Silla continues to operate beyond 2006 with only two telescopes: the NTT and the 3.6m.

Abstract:
During astronomical observations it has always been of great importance to be able to asses the quality of the data being collected at the telescope and the conditions of the night. The way astronomers normally do this is by processing the raw data transmitted from the instrument workstation with some semiautomated software package. The data reduction normally depends on the instrument characteristics, but basically the main divisions are set by the wavelength range covered (optical, infrared, sub-millimetric, radio) and by the way the light is collected (imaging or spectroscopy).

Abstract:
The FORS instruments at the ESO VLT have been used to study the cosmic evolution of galaxies. From a large sample of distant galaxies observed near the South Galactic Pole we obtained new results on the physical properties of high-redshift galaxies, on the evolution of the galaxy luminosity function and of the cosmic star formation rate, on the chemical enrichment of the universe, and other signposts for changes with cosmic time.

Abstract:
The variation of several fundamental constants in physics can be probed by measuring wavelengths of atomic transitions in the high redshift Universe. In particular any possible variation in the electromagnetic fine-structure constant (α = e²/ℏc) can be detected in the absorption spectra of distant quasars. Using a well defined sample of absorption line systems we derive a 3σ upper limit on the time variation of α of ‑2.5 × 10-16 yr-1 ≤ (Δα / α Δt) ≤ +1.2 × 10-16 yr-1.

Abstract:
Radial velocity follow-up of 41 OGLE planetary transit candidates carried out with the multi-object spectrograph FLAMES on the 8.2-m VLT Kueyen telescope has revealed the existence of Jupiter-mass companions around two transit candidates. They are extremely close to their host stars, orbiting them in less than 2 days.

Abstract:
OVER THE LAST FEW years, the idea of a “European Research Area” (ERA) has gained strong support among science policy makers and, increasingly, among scientists themselves. The goal of the ERA is to establish a single “market” for research on our continent, allowing for better co-ordination of research efforts, synergies between projects, the achievement of “critical mass” (both human and financial) and thus to strengthen the competitiveness of European research. These goals necessitate deep structural changes in the way science is organised, breaking up existing borderlines and barriers between national research systems in Europe.

Abstract:
This three-day ESO workshop, held from 19 to 21 May 2004, devoted to extra-galactic planetary nebulae (PN), was the first full workshop on the topic. Previously there had been discussions of extra-galactic PN on the final day of the pentennial IAU Symposium on Planetary Nebulae (last held in Canberra in 2001) and a one day meeting during the IAU General Assembly in den Haag in 1994. The field has expanded considerably in the last decade with many PN now detected in Local Group galaxies, extensive surveys underway in nearby early-type galaxies and in the intergalaxy regions of galaxy clusters, together with the use of PNe as kinematic probes for galaxy potentials. There are currently many thousands of PN catalogued in external galaxies, far surpassing the approximately 1500 known in the Milky Way.

Abstract:
ESO is committed to producing and maintaining a data stream from the VLT Observatory that forms a data heritage for international astronomy. This goal is being realised by an end-to-end operational approach that maintains data integrity, produces appropriate metadata, maintains and executes calibration plans and produces quality controlled data products. ESO has also designed and produced advanced data products from surveys that are available from the ESO/ST-ECF Science Archive Facility (SAF) and which feed archival science programs and future applications for VLT time. ESO also wishes to ensure that the full scientific potential of the VLT is realised by granting large amounts of telescope resources to large programmes chosen on scientific merit by the Observing Programme Committee (OPC). To ensure that the scientific products from these programmes also form an effective part of the VLT data heritage and the emerging international virtual observatory, ESO is defining requirements and procedures for large programmes that will ensure their scientific output can be published through the SAF. This goal is directly supported by the recommendations of the recent ESO workshop on Large Programmes and Surveys, endorsed by the Scientific Technical Committee (STC) at its April 2004 meeting.
