Abstract:
The evolution of ESO is briefly traced through its technical and managerial developments to today. Highlights of ESO activities in support of astronomical research by the member state community are given to emphasise the unique role of the Organisation in European astronomy, and the effectiveness with which it has carried out its mission, including the development of VLT/VLTI.

Abstract:
SOFI, ESO's new 1 - 2.5 μm infrared imager/spectrometer, was installed at the NTT on La Silla in early December 1997 and saw first light as planned on the 6th. The acronym stands for Son OF ISAAC, the larger and more complex infrared instrument being built by ESO for the VLT. In addition to significantly enhancing the infrared observing capabilities on La Silla, SOFI has also provided valuable experience within the 'VLT environment' now existing at the upgraded NTT telescope.

Abstract:
At its meeting in Milan in October 1996, the STC recommended the procurement of 2 instruments for imaging and massive multi-object spectroscopy, VIMOS and NIRMOS, as conceptually designed by the VIRMOS consortium. The STC further recommended that ESO reduce the overall development time to ensure that these new instruments are competitive, with respect to e.g. DEIMOS on the Keck telescope and GMOS on the Gemini Telescope.

Abstract:
The relatively quiet situation that had prevailed at the NTT since the return into operations (see the News from the NTT of The Messenger No. 90) has come to an abrupt end beginning of December. Since then, the NTT has been the scene of a quick succession of events, which will be reported below in chronological order of occurrence.

Abstract:
The bad behaviour of the lateral pneumatic support of the main mirror (M1) has already been put forward several times to explain the bad image quality of the telescope at large zenith distance. In order to check this assumption, several adjustments were done on the primary mirror support during the technical time last December. We decided to start by recentring the mirror axis on the rotator axis. This was done successfully and we found that the old position of the mirror was about 2 mm away from the rotator axis position. All the lateral pads supports were modified, and it is now possible to adjust them radially to match the new mirror position.

Abstract:
The Swedish-ESO Submillimetre Telescope (SEST) has been in operation successfully for close to 10 years, the first scheduled observations having taken place in April 1988. It has served not only the Swedish-ESO community, but 10% of the Swedish observing time has been used by Finnish astronomers and, recently, Australia has signed an agreement with Sweden, also for 10% of Swedish observing time. The SEST receivers have been upgraded on a regular basis during the past decade, but the original control system is still in place. However, during the past couple of years an in-house project to replace this control system as well as the old computers has been in progress, while continuing normal observations. The project is being carried out by the SEST engineers with assistance from the staff at Onsala Space Observatory and will be completed during 1998. This article will describe the present instrumentation, the new control system and give a brief overview of the plans for the SEST during the coming years.

Abstract:
Molecular absorption lines at high redshift (0.2 to 1) were discovered a few years ago, and they revealed a very precious tool for many purposes. The excitation temperatures of molecules are often close to that of the cosmic background radiation, and can serve to measure it as a function of redshift.

Abstract:
Many very interesting results in the field of observational Cosmology have been obtained in the past with the 15-m Swedish ESO Submillimetre Telescope (SEST) at La Silla (see the ESO/ STC-148 Report on Submillimetre Astronomy at ESO). The technical upgrades and improvements foreseen for SEST will undoubtedly boost projects in this field which, after a very successful start a few years ago, suffered a loss of competition with respect to other available sub-mm/mm facilities (i.e. IRAM, JCMT).

Abstract:
The activity of galaxies reaches from the enhanced star-formation rate to the outburst of quasars. These different aspects of converting cold gas into luminosity can be well described by the ratio of infrared luminosity versus gas mass. The process of star formation is characterised by LIR/Mgas values of 5 [Lsun/Msun] in normal spirals and 100 in active Mkn galaxies while quasars attain values above 500 due to additional non-thermal processes. Moreover, the coldest dust component in extragalactic objects also seems to be correlated with the stage of activity. New ISOPHOT data between 60 and 200 μm and SEST data at 1300 μm corroborate these results for active galaxies but indicate the presence of very cold dust (≍10 K) in normal spirals. The implications on the total gas content of galaxies are discussed.

Abstract:
Thanks to the good angular resolution of the SEST, much progress has been done on the properties of molecular gas in the Magellanic Clouds, and this is outlined in the paper. A substantial fraction of the Clouds has been mapped in the CO lines at a linear resolution of about 10 pc, sufficient to resolve the ordinary molecular clouds inside large gas complexes. Multi-line observations have allowed to explain why these clouds look different in CO than Galactic clouds.

Abstract:
The Magellanic Clouds provide an extremely interesting environment to study astrophysical processes. With respect to the molecular interstellar medium, there are three outstanding properties which motivate ongoing research: (1) Metallicities are smaller than in the Milky Way, (2) UV radiation fields are stronger than in the solar neighbourhood, and (3) a large number of targets is found at a well-known (relatively small) distance. The first two properties have far-reaching consequences for the astrophysical and astrochemical state of the interstellar medium.

Abstract:
1999 will be the first year of the VLT scientific operations, yet this will not be the only novelty brought by the new year. In 1999 the flow of scientific data from the old La Silla Observatory will be several times higher than in 1998. Indeed, with the full dedication of the ESO/MPIA 2.2-m telescope to wide-field imaging, the ESO community will have for the first time an efficient survey instrument: the 8k ´ 8k camera covering a 0.54° ´ 0.54° field of view. In the meantime, the construction is about to start of a new 2.5-m telescope to be placed on Paranal by 2001, which will have a four times bigger field of view (and data flow rate). This sudden expansion of ESO widefield imaging and survey capabilities requires a major effort by both ESO and its community, in order to take full advantage of these new facilities that are primarily designed to support and foster the science to be done with the VLT.

Abstract:
ST-ECF and ESO are organising in collaboration with the NICMOS IDT and STScI a workshop on near infrared imaging from space and ground. The purpose of the workshop is to review what has been achieved with the Near Infrared and Multi Object Spectrograph (NICMOS) on board of HST, what can be achieved in the remaining lifetime of the instrument, and how NICMOS observations can be optimised taking into account the availability of IR imaging and spectroscopy on ESO’s Very large Telescope (VLT) in the near future. The meeting will be held in May 1998, about one year after science observations started with NICMOS, and about half a year before the Infrared Spectrometer and Array Camera (ISAAC) starts to operate on the VLT. Currently, it is expected that NICMOS will operate until the end of 1998.

Abstract:
Following the recommendation of the “HST and beyond” Report, NASA is investing a considerable effort in the definition of a large aperture (8 meter class) near IR space telescope (known as the Next Generation Space Telescope) to study the Universe at high redshift (5 < z < 30) and in particular the formation and evolution of galaxies at that early epoch. ESA has recently decided to join NASA in these preliminary studies in view of a possible future collaboration in the construction and operation of such an important astronomical facility. ESO is also supporting a European participation in NGST because of the scientific complementarity between VLT and NGST observing programmes.
