Abstract:
There has been a continuous growth in applications for ESO telescopes from the first calls for proposals in the late 1960s. Typically one thousand applications are now received per semester involving over 3000 astronomers worldwide. A brief history of the evolution of the allocation process is presented and a snapshot of the current procedures is given.

Abstract:
With over 1000 proposals per semester for ESO telescopes, the community is facing the problem of fair and robust selection of observing programmes. We report here on a working group to investigate the current selection process and procedures and identify possible improvements. The working group report summarises the current process, based on peer review, that has been in use for many years at ESO and other comparable ground- and space-based observatories, and presents an inventory of the changes and approaches that may be considered to make the process more manageable and less time-consuming, while at the same time preserving its integrity. The working group presented several recommendations, which have been discussed with ESO committees and analysed by the operational groups at ESO.

Holographic Imaging: A Versatile Tool for High Angular Resolution Imaging

Abstract:
Speckle holography can be used to reconstruct high angular resolution images from long series of short exposures if the point spread function (PSF) from each frame can be measured reliably. We show that through use of multiple reference stars and iterative PSF subtraction, we can obtain highly accurate PSFs. The technique is optimised for crowded fields and results in images with excellent cosmetics and high Strehl ratio from the optical to the mid-infrared regimes. With examples from NACO, VISIR, and HAWK-I we show that holography opens up novel and unforeseen possibilities and can be an attractive alternative to adaptive optics.

Abstract:
The ESO 3D visualisation tool provides the capability for visualisation and basic scientific exploitation of 3D spectroscopic datasets obtained with VLT integral field unit instrumentation, including MUSE. The tool was implemented as part of the ALMA CASA software viewer and as such provides the opportunity to view ALMA data as well as VLT 3D data within the same tool. Recently, the first version of the visualisation tool, featuring optical and near-infrared spectroscopic capabilities, has been completed and we describe the released software which is available for Mac OS X and Linux systems.

Abstract:
In 2009, the ESO 1.0-metre Schmidt telescope at La Silla was awakened from an 11-year slumber. The telescope had been decommissioned in 1998 after completing a photographic survey of the southern hemisphere. It has now been given a new life with the installation of Yale University’s 160-megapixel QUEST camera consisting of a 112-CCD mosaic covering 10 square degrees. The control system for the telescope was also upgraded to allow fully autonomous observing. With the new system, Yale is conducting the La Silla–QUEST (LSQ) Variability Survey in the Southern Hemisphere to detect low-redshift supernovae, RR Lyrae variable stars, Kuiper Belt Objects (KBOs), and other unusual transients. The LSQ variability survey has already covered most of the southern hemisphere multiple times at cadences ranging from hours to years and to a depth ranging from R magnitudes 20.5 to 21.5. To date the survey has detected more than 65 new KBOs and thousands of new RR Lyrae stars. The detection of hundreds of supernovae will lead to an improved measurement of the accelerated expansion rate of the Universe.

Abstract:
Shortly after its discovery in 1984, the Beta Pictoris disc was recognised as a possible site of past, ongoing or future planet formation. It has since been observed extensively, from the X-ray domain to centimetre wavelengths by many ground- and space-based telescopes. The disc has become a remote laboratory to study the physical and chemical characteristics of debris discs. Recently, we were able to detect a companion orbiting the star at a distance comparable to that of Saturn in our Solar System. The β Pic system thus offers a unique opportunity to study giant planet properties and planet/disc interactions. We present a short — and necessarily incomplete — review of the main discoveries made in this fascinating system over three decades of observations, a number of which were achieved with ESO telescopes.

Abstract:
The long-period Cepheid RS Pup illuminates its circumstellar dust cloud with a variable flux, and creates spectacular light echoes. Through photometric observations of this phenomenon with NTT/EMMI, and polarimetric imaging with VLT/FORS, we have derived the geometric distribution of the scattering dust and the total mass of the nebula. We conclude that the dust was not created by mass loss from the Cepheid, but is most probably a remnant of the interstellar material from which the Cepheid formed.

Abstract:
COSMOGRAIL is a long-term programme for the photometric monitoring of gravitationally lensed quasars. It makes use of several medium-size telescopes to derive long and well-sampled light curves of lensed quasars, in order to measure the time delays between the quasar images. These delays directly relate to the Hubble constant H0, without any need for secondary distance calibrations. COSMOGRAIL was initiated in 2004, and has now secured almost a decade of data, resulting in cosmological constraints that are very complementary to other cosmological probes.

Abstract:
Astronomers have been debating the origin of galaxies for centuries and the timeline of the evolution is now well established. However, despite the success of galaxy formation models, some questions remain largely unanswered. Chief among them is how the first galaxies formed. When the Universe was in a highly opaque state, these first galaxies most likely cleared the cosmic fog and broke the cosmic dawn. However, there are large uncertainties as to how this transition occurred and what the exact role of the first galaxies was. Using galaxy clusters as cosmic telescopes that magnify background objects, we were able to detect hydrogen emission from a galaxy at a redshift of z = 6.740 ± 0.003 using FORS2 on the VLT. To date, this is the faintest galaxy with a successfully measured spectrum and as such an important beacon for cosmic dawn.

Abstract:
Roughly half the star formation in the young Universe is thought to have been heavily obscured by dust and molecular gas. A new suite of facilities and experiments operating at submillimetre through to centimetre wavelengths is providing astronomers with the ability to study galaxies whose star formation and AGN activity would be partially invisible to optical telescopes. The most sensitive of these new instruments is ALMA. Even with only a subset of the final number of 12-metre antennas operational, the first ALMA observations are providing sensitive, unobscured images of the formation of massive galaxies. Observations of BR1202-0725 at z = 4.7 are described as an example.

Abstract:
Over 100 participants gathered to present and discuss the first exciting results from the eleven ESO public survey programmes in the context of current and planned major ground- and space-based surveys. The VISTA and VST public surveys presented a wide range of new scientific results. Presentations of other current or planned large ground- and space-based projects provided a benchmark for the ESO public surveys and their relevance worldwide.

Abstract:
Since 1974, The ESO Messenger has been one of ESO’s primary communication channels to the outside world in particular. It has provided a window not only onto the organisation, its projects and people, but also onto the research carried out by ESO’s ever-growing user community. Last but not least, today it constitutes a fascinating historical source, documenting the life and evolution of ESO over the last 38 years.
