Abstract:
I am delighted to welcome the Czech Republic as our 13th member state. From its size, the Czech Republic may not belong to the ‘big’ member states, but the accession nonetheless marks an important point in ESO’s history and, I believe, in the history of Czech astronomy as well. The Czech Republic is the frst of the Central and East European countries to join ESO. The membership underlines ESO’s continuing evolution as the prime European organisation for astronomy, whilst at the same time it enables Czech astronomers to become fully integrated in the European astronomical community.

Abstract:
Ground-based observations in the ultraviolet part of the electromagnetic spectrum are notoriously difficult owing to absorption of the atmosphere, of optical elements and the poorer efficiency of detectors. Now that CCD detectors with excellent UV response and cosmetic quality have become available, it was time to optimise FORS1 for imaging, low-resolution spectroscopic and polarimetric observations in the blue-UV. As a bonus, a new set of broadband filters with very high trans-mission and carefully defined filter bands were installed.

Abstract:
The two FOcal Reducer and low-dis-persion Spectrographs (FORS) are the primary imaging instruments for the VLT. Because they are not direct imaging instruments, the accuracy of photometry which can routinely be obtained is limited by significant sky concentration and other effects. This article reports on the progress of a long-term project to improve the photometric calibration of the FORS instruments.

Abstract:
The Active Phasing Experiment (APE) is part of the Extremely Large Telescope Design Study which is supported by the European Framework Programme 6. This experiment, which is conducted in collaboration with several partners is a demonstrator to test and qualify newly-developed phasing sensors for the alignment of segmented mirrors and test the phasing software within a telescope control system to be developed for a future European Extremely Large Telescope. The segmentation of a primary mirror is simulated by a scaled-down Active Segmented Mirror of 61 segments which has been developed in-house.

Abstract:
In order to obtain a census of planets with masses in the range of Earth to Jupiter, eight telescopes are being used by the combined microlensing campaign of the PLANET and RoboNet collaborations for high-cadence photometric round-the-clock follow-up of ongoing events, alerted by the OGLE and MOA surveys. In 2005 we detected a planet of 5.5 Earth masses at 2.6 AU from its parent 0.22 MA M star. This object is the first member of a new class of cold telluric planets. Its detection confirms the power of this method and, given our detection efficiency, suggests that these recently-detected planets may be quite common around M stars, as confirmed by subsequent detection of a ~ 13 Earth-mass planet. Using a network of dedicated 1 2-m-class telescopes, we have entered a new phase of planet discovery, and will be able to provide constraints on the abundance of frozen Super-Earths in the near future.

Sulphur Abundances in Metal-Poor Stars First Result from CRIRES Science Verification

Abstract:
Sulphur is the tenth most abundant element in the Universe and plays an im-portant role in studies of the chemical enrichment and star formation history of distant galaxies. Due to the lack of suitable sulphur lines in the visible part of stellar spectra there is, however, still no agreement on the abundance of sulphur in Galactic metal poor stars, and we are therefore uncertain about the nucleosynthetic origin of sulphur. New observations of infrared sulphur lines with the cryogenic high resolution infrared echelle spectrograph (CRIRES) at ESO’s VLT are helping to solve this problem.

Using Globular Clusters to Test Gravity in the Weak Acceleration Regime

Abstract:
We report on the results from an ongoing programme aimed at testing Newton’s law of gravity in the low acceleration regime using globular clusters. We find that all clusters studied so far behave like galaxies, that is, their velocity dispersion profiles flatten out at large radii where the acceleration of gravity goes below 10 8 cm s 2, instead of following the expected Keplerian fall-off. In galaxies this behaviour is ascribed to the existence of a dark matter halo. Globular clusters, however, are not supposed to contain dark matter, hence this result might indicate that our present understanding of gravity in the weak regime of accelerations is incomplete and possibly incorrect.

Abstract:
The new VLT instrument SINFONI gives us a view onto the circumnuclear properties of AGN in unprecedented detail, even beyond our local Universe. As a science verification target, the showcase object Mrk 609 demonstrates impressively the necessity of adaptive optics assisted integral-field spectroscopy in order to distinguish between Seyfert and starburst characteristics on nuclear scales.

Abstract:
GHostS is the largest public data-base on gamma-ray burst (GRB) host galax-ies and is accessible at the URL http://www.grbhosts.org. Started in 2005, it currently contains photometric and spectroscopic information on 39 GRB hosts, almost 2/5 of the total number of GRBs with measured redshift. It will continue to grow, together with the unstoppable data flow from the obser-vatories all over the world, every time a new event is discovered. Among other features, GHostS uses the Virtual Observatory resources.

Abstract:
Observations of high-redshift galaxies show that at early cosmic epochs the cosmic UV radiation field appears to be dominated by small galaxies with strong Ly-alpha emission. Although usually small and of relatively low luminosity, these galaxies are easily identified from their line emission. Observations with the VLT resulted in significant progress in the understanding of the nature of these distant galaxies and of their role in the early Universe.

Abstract:
The productivity and scientific impact of observatories and individual instruments are one measure of their success. This article presents the results of a study where we have applied the h-index, previously proposed for individual researchers, to major ground-based observatories (VLT, Keck, Gemini, Subaru) as well as individual VLT instruments. The concept is expanded by exploring the time-dependence of the h-index h(t). Overall, the VLT appears to be among the most successful 8-m-class telescopes. We also show that ESO instruments are making important contributions to progress in astronomy.

Author(s)/Affiliation(s):
Sterzik, M.; Dumas, C.

Abstract:
Nowadays, the ESO premises in Vitacura host more than 80 PhD students, fel- lows and astronomers, and represent the research centre for the scientific staff de-ployed at the different observatory sites in Chile. Several topical working groups help locally to actively promote and foster joint research initiatives among ESO sci-entists. One example is the “Planetary Sciences Research Group” at ESO Chile (http://www.sc.eso.org/santiago/science/PlanetaryGroup), which seeks to understand the formation of planetary systems at large and the place occupied by our own Solar System. Group members are actively involved in observation-oriented programmes making use of ESO facilities to carry out front-line research ranging from discoveries of new brown dwarfs and exoplanets, to the study of primitive Solar System bodies.
