ESO Period 103 Proposal Submission Statistics

08 Oct 2018:

The deadline for proposal submission for Period 103 (1 April 2019 - 30 September 2019) was 27 September, 2018. 914 valid proposals were submitted, including 20 Large Programmes, of which one is a GTO Large Programme. The number of proposals for Period 103 is very similar to that of Periods 91 (893), 92 (892), 93 (898), 94 (901), 98 (901), 99 (887), 100 (895), 101 (899) and 102 (916) so the plateau observed since peaks in Periods 95 (934), 96 (960) and 97 (1024) remains. On the VLT the most requested ESO instrument was X-shooter with 258 nights, followed by MUSE with 226 nights, and FORS2 with 145 nights. HARPS on the ESO 3.6-metre was the most demanded instrument at La Silla, with a request of 190 nights, though the combined request on the NTT was larger (246 nights).

Message to Volunteers Testing Distributed Peer Review Process

07 Oct 2018:

The response to our call for volunteers for the Distributed Peer Review (DPR) experiment was very enthusiastic, well beyond our original expectations. Out of the 272 scientists that had initially expressed their interest, 172 (63%) submitted a proposal for Period 103 as Principal Investigators (PIs) and will hence serve as reviewers. This corresponds to about 23% of all PIs in Period 103. This is also a reminder that the DPR process will run in parallel to the regular proposal review by the Observing Programmes Committee and will have no effect on the final ranking of the proposals.

ESO wishes to warmly thank its community for the enthusiastic response and collaborative spirit, which will ensure the success of the experiment! An in-depth analysis of the experiment and its results will be presented in due course.

Workshop: Preparing for 4MOST

06 Oct 2018:

ESO, Garching, Germany, 6–8 May 2019

4MOST is a state-of-the-art, high-multiplex, optical spectroscopic survey facility currently under construction for ESO’s 4-metre VISTA telescope. During the first five years of operations 4MOST will be used to execute a comprehensive programme of both Galactic and extragalactic Public Surveys, and 30% of the observing time during this period will be available to the community. The process of selecting Community Public Surveys will be initiated by a Call for Letters of Intent for Public Spectroscopic Surveys, to be issued by ESO in mid-2019. In preparation of this Call, ESO and the 4MOST Consortium are jointly organising a workshop to prepare the ESO community for this exciting scientific opportunity, to assist potential PIs in successfully responding to the Call, and to foster scientific collaborations between the community and the 4MOST Consortium.

Workshop: The Very Large Telescope in 2030

05 Oct 2018:

ESO, Garching, Germany, 17–21 June 2019  

The VLT provides a powerful suite of visible and infrared instruments, including unique capabilities like coherent and incoherent combinations of the four 8-metre Unit Telescopes and a multi-laser guided adaptive optics system.  In combination with ALMA, it represents comprehensive coverage across  the full parameter space encompassing ground-based observations in visible, infrared and sub-mm wavelengths. With the advent of ESO's Extremely Large Telescope (ELT) the VLT will take on a new role. It will still serve a large community and will continue to provide unique data. Its strengths will include a suite of versatile instrumentation on four 8-metre telescopes, the spatial resolution achievable by interferometry and a flexible operational model. The VLT, VLTI and the instrumentation have been maintained at peak performance and new capabilities have been developed.

A discussion of future science served by the VLT should be the basis for its development in the ELT era. The ELT, VLT in its many functions and the ESO 4-metre telescopes will form a powerful astrophysics resource. The new role of the VLT needs to be defined and this workshop will provide a discussion forum aimed at shaping the VLT's future.

Workshop: The La Silla Observatory - from the inauguration to the future

04 Oct 2018:

La Serena, Chile, 25–29 March 2019

The La Silla Observatory was officially inaugurated on 25 March 1969. This event marked the culmination of the vision of European astronomers to create a major observatory in the Southern Hemisphere. In the following decades, La Silla served as the test-bed for developing technical and scientific expertise in the European astronomical community, establishing communications channels with the public at large and the interaction of an inter-governmental organisation and its host country, Chile. Relations with other astronomical facilities in the Andes mountains are also part of its history. La Silla has served as a superb site where national communities of ESO member states could install their experiments; some of these facilities regularly put the La Silla Observatory in the news. This conference celebrates the 50th anniversary of the inauguration of La Silla. We will review the significance of its history in all aspects and discuss possible future scenarios. The history of the Observatory including all of its many facets, and the research areas where La Silla telescopes have made important contributions will be reviewed.

MUSE Narrow Field Mode AO Commissioning Data

03 Oct 2018:

The commissioning runs of MUSE in Narrow-Field Mode Adaptive Optics (NFM-AO) were carried out at the VLT on UT4 in April and June 2018. Several astronomical targets were observed to demonstrate the the capability of this new mode, find the best observing strategies and optimise the performance of the pipeline data reduction. The commissioning data have been released to illustrate the power of LTAO correction with MUSE NFM on different science targets; they can also be used as a reference to plan future programmes.

New Features for the ESO Archive Science Portal

02 Oct 2018:

ESO’s Archive Science Portal provides an intuitive yet very powerful way of browsing, searching and downloading reduced science-ready data. Since the initial rollout three months ago, it has already been visited by more than approximately 1700 users (as inferred from the count of distinct IP addresses). Based on user feedback a new view mode has been implemented as a central new feature in addition to the already existing sky view (left-hand panel of figure above). It allows users to inspect, at a glance, the multi-dimensional query space in up to seventeen 1D distributions (right-hand panel of figure). They include physical parameters like sensitivity and signal-to-noise ratio, alongside more traditional ones such as Programme ID or instrumental setup. Users can easily interact with any list or histogram to add or remove search constraints and to build up rather complex queries in a progressive fashion.

Data Release: VANDELS ESO Public Spectroscopic Survey

01 Oct 2018:

VANDELS  is a deep Public Spectroscopic Survey of high-redshift galaxies with the VIMOS spectrograph. It is designed to exploit the multi-wavelength imaging and near-infrared grism spectroscopy available in the CANDELS UDS and CDFS fields. The goal is to obtain spectra with sufficient signal-to-noise to derive metallicities and velocity offsets for absorption and emission lines independently, allowing a detailed investigation of the physics of galaxies in the early Universe. Within an area of 0.2 square degrees, the survey aims at delivering more than 2500 high signal-to-noise (~15-20) spectra of star-forming galaxies in the redshift range 2.5 < z < 5.5 and passive galaxies in the redshift range  1.5 < z < 2.5. This second data release (DR2) is based on observations carried out between August 2015 and August 2017 under the ESO Run IDs 194.A-2003(E-Q).

Upcoming ESO or ESO-Related Workshops

  • Take a Closer Look – The Innermost Region of Protoplanetary Discs and its Connection to the Origin of Planets
    ESO Headquarters, Garching, Germany, 15–19 October, 2018

    Recent discoveries of close-in planets around main sequence and even pre-main sequence stars raise a number of questions about the formation of planetary systems. Their formation and migration history must be directly linked to the conditions within the inner regions of their progenitor protoplanetary discs. These sites also play a key role in star-disc interactions. Studies probing this important region require the use of innovative techniques and a wide range of instruments.
    This workshop will address a number of topics related to the inner disc, including the morphology and composition of the innermost disc regions, star-disc interaction, and theories that describe the evolution of the innermost disc regions and the formation of close-in planets.

  • KMOS@5: Star and Galaxy Formation in 3D – Challenges at KMOS 5th Year
    ESO Headquarters, Garching, Germany, 3–6 December, 2018

    KMOS is one of the second generation instruments at the ESO-VLT and has been operating for five years, over which it has provided new insights into a variety of scientific topics.This workshop will bring together scientists working on all areas of star and galaxy formation using near-infrared IFU spectroscopy, including results from complementary instruments. The five years milestone of KMOS offers a perfect opportunity to assess the impact of this instrument on its core science cases and to look forward to develop new strategies and programs, also in light of future IFU instruments. Science topics include probing galaxy formation, stellar populations, active galactic nuclei and their relation with the host galaxy. 

  • The Galactic Bulge at the Crossroads
    Pucón, Chile, 10–14 December, 2018

    The bulge is a primary component of the Milky Way, comprising ∼25% of its mass. All major Galactic stellar populations intersect there, reaching their highest densities. Exploring the bulge is fundamental to understanding Galactic formation, structure and evolution. With the advent of multiplexed spectrographs on 8-metre class telescopes, and the availability of wide-field near-infrared photometry, our knowledge of the structural, chemical and kinematical properties of the Galactic bulge has improved dramatically in the last few years. At the same time, the interpretation of the data is not straightforward, and many fundamental questions remain. In this context, a host of exciting new results are expected in 2018. This conference aims to gather the international astronomical community to discuss these developments, and to begin to establish a consensus on their interpretation.
