Abstract:
TRAPPIST is a 60-cm robotic telescope that was installed in April 2010 at the ESO La Silla Observatory. The project is led by the Astrophysics and Image Processing group (AIP) at the Department of Astrophysics, Geophysics and Oceanography (AGO) of the University of Liège, in close collaboration with the Geneva Observatory, and has been funded by the Belgian Fund for Scientific Research (F.R.S.-FNRS) and the Swiss National Science Foundation (SNF). It is devoted to the detection and characterisation of exoplanets and to the study of comets and other small bodies in the Solar System. We describe here the goals of the project and the hardware and present some results obtained during the first six months of operation.

Abstract:
Interferometric observations require frequent measurements of calibration stars of known diameter to estimate the instrumental transfer function. ESO offers the preparation tool CalVin to select suitable calibrators from an underlying list of calibrators. The latest version 3, first released in January 2011, offers major improvements in the number of available calibrators, the functionality of the search tool, as well as in terms of performance and ease of use. It has been developed in a collaboration between ESO and the French Jean-Marie Mariotti Center (JMMC).

Abstract:
With the advent of many large-area imaging surveys in recent years, the need for a new facility for spectroscopic surveys has become apparent. Following a recommendation from the Science and Technical Committee, ESO made a call in 2010 for wide field spectroscopic instrument proposals among its community. Two of the ten proposals were selected for a competitive Phase A study. This article describes the selection process and two associated articles present the instrument concepts.

Abstract:
ALMA is rapidly progressing towards the end of the construction phase. At the beginning of August 2011, 17 antennas were interferometrically linked on the Chajnantor plateau at an altitude of 5000 metres. Twelve-metre antennas from all the vendors were used in this experiment, which is a major milestone towards the first Early Science guest observer observations, currently planned to begin soon. In the meantime, ALMA Science Verification datasets are becoming available on the ALMA webpages for users to download and gain familiarity with ALMA data reduction and analysis procedures.

Abstract:
The dwarf planet Pluto and Neptune's largest satellite, Triton, are two small icy bodies surrounded by tenuous and poorly known atmospheres. The high spectral resolution and high sensitivity of CRIRES on the VLT have permitted a major step forward in the study of these atmospheres, and especially of their composition. Absorptions due to methane and carbon monoxide in these atmospheres have been detected at 1.66 and 2.35 µm, providing an insight into the way in which these atmospheres are maintained, the surface-atmosphere interactions, their seasonal evolution and thermal balance.

Abstract:
Mass loss from asymptotic giant branch (AGB) stars is the most important driver for the evolution of low to intermediate mass stars towards planetary nebulae. It is also one of the most important sources of chemical enrichment of the interstellar medium. The mass-loss process originates in the extended atmosphere, whose structure is affected by stellar pulsations, and where molecular and dusty layers are formed. Optical interferometry resolves the extended atmospheres of AGB stars and thereby enables us to obtain measurements of the intensity profile across this region. We present an overview of recent results from our spectro-interferometric observations of AGB stars using the near- and mid-infrared instruments AMBER and MIDI of the VLT Interferometer.

Abstract:
As part of the VISTA Science Verification programme, a large set of images in Orion was obtained at five near-infrared wavelength bands, from 0.9 to 2.2 μm. The resulting multi-band catalogue contains approximately three million sources, allowing investigation of various issues concerning star and brown dwarf formation, such as a) the difference in the shape of the substellar mass function in a cluster vs. non-clustered environment, b) the influence of massive OB stars on the process of brown dwarf formation, c) the size and morphology of dust envelopes around protostars, and d) the comparative role of mass and environment on the evolution of circumstellar discs. The data from the VISTA Orion Survey, including catalogues, are available to the community. In this article we present an overview of selected science results that have emerged so far from this survey.

Abstract:
We introduce the VLT FLAMES Tarantula Survey, an ESO Large Programme from which we have obtained optical spectroscopy of over 800 massive stars in the spectacular 30 Doradus region of the Large Magellanic Cloud. A key feature is the use of multi-epoch observations to provide strong constraints on the binary fraction. This is the largest high quality survey of extragalactic massive stars ever assembled, and is already providing exciting new insights into their evolution, multiplicity and formation.

Abstract:
In recent years, major advances have been made in our understanding of the early stages of galaxy formation and evolution. Remarkable progress has come from spatially- and spectrally-resolved studies of galaxies beyond z ~ 1 with SINFONI at the VLT, when the Universe was less than 40% of its present age. Here we report on key insights from our SINFONI observations of over 100 massive z ~ 2 star-forming galaxies, resolving the kinematics, physical, and star formation properties on scales of ~ 1-5 kiloparsecs.

Abstract:
Our knowledge of the formation and evolution of distant galaxies continues to advance dramatically with the advent of new facilities at most observable wavelengths. One of the outstanding questions related to this field is: How do galaxies get their gas? Over the next decade, radio and submillimetre facilities like the Expanded Very Large Array and the Atacama Large Millimeter/submillimeter Array will probe the chemistry, kinematics and obscured star formation properties of the interstellar medium in galaxies at high redshift, allowing this question to be addressed. We report on a timely workshop on the roles of theory and multi-wavelength observing facilities in furthering our understanding of interstellar medium physics in distant galaxies.

Abstract:
Alan Moorwood died on 18 June 2011 at the age of 66 after a short illness. He had recently retired from ESO as Director of Programmes, having played a leading role in instrumentation for many years. There follows an obituary by Tim de Zeeuw and a joint tribute by three of his long-time ESO colleagues, Bruno Leibundgut, Bob Fosbury and Sandro D’Odorico.
