Workshop: La Silla Paranal Users Workshop – Getting Science Done with Your Observatory

Published: 10 Oct 2017

ESO Headquarters, Garching, Germany, 12–14 March 2018

ESO's ground-based observatories located in Chile serve a very diverse astronomical community. The La Silla Paranal observatory offers observations with a variety of telescopes, instruments and observing modes and a wide ranging level of user support. If you are a La Silla Paranal Observatory user and are interested in face-to-face contact with the various support services at ESO, this workshop is for you. The workshop will provide you with all the necessary knowledge to make the most out of ESO data and thereby provide a strong momentum to your science. Further details are available below and via the workshop website, which also has a preliminary programme.

Workshop: Atacama Large-Aperture Submm/mm Telescope (AtLAST)

Published: 10 Oct 2017

ESO Headquarters, Garching, Germany, 17–19 January 2018

ESO is co-organising a workshop on the scientific merit for – and technical implementation of – an Atacama Large Aperture Submm/mm Telescope (AtLAST). The workshop will be a crucial forum to collect insights and feedback, and commit to a single vision for realising a single dish facility. The programme will cover aspects of the science case driving the telescope and instrument requirements as well as potential telescope concepts.

Workshop: Diversis Mundi – The Solar System in an Exoplanetary Context

Published: 09 Oct 2017

ESO, Santiago, Chile, 5–9 March 2018

This one-week workshop is the third edition of the Observing Planetary Systems workshop (OPS-III) held every 5 years at ESO-Chile, which aims to bring together  Solar System and exoplanet scientific communities. The discovery of exoplanetary systems with a large variety of architectures can teach us about the formation and history of our own solar system, and the deep understanding of our own environment can help us search for traces of life outside of the Solar System.  

Workshop: Imaging of Stellar Surfaces

Published: 09 Oct 2017

ESO Headquarters, Garching, Germany, 5–9 March 2018

There have been tremendous recent advances in observational techniques enabling resolution of the surfaces of stars other than the Sun. Current and planned VLTI instruments, SPHERE on the VLT and ALMA, as well as other interferometric facilities, have recently succeeded in resolving stellar surfaces. The workshop aims to bring together observers from different techniques and wavelengths, and theoreticians working on stellar atmospheres and stellar structure.

Workshop: Take a Closer Look – The Innermost Region of Protoplanetary Discs and its Connection to the Origin of Planets

Published: 08 Oct 2017

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.

VANDELS Public Spectroscopic Survey: First Data Release

Published: 05 Oct 2017

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-IR grism spectroscopy available in the CANDELS UDS and CDFS fields. The goal is to obtain spectra with sufficient signal-to-noise ratio to derive metallicities and velocity offsets from absorption and emission lines, allowing a detailed investigation of the physics of galaxies in the early Universe. Within an area of 0.2 deg2, the survey will deliver more than 2500 high (15-20) signal-to-noise spectra of star forming galaxies in the redshift range 2.5 < z< 5.5, passive galaxies with H< 22.5 at 1.5 < z < 2.5, and star forming galaxies at 3.0 < z < 7.0 with H < 27, in the AB magnitude system.

VISTA VIKING Release of Images, Source Lists and Multi-band Catalogue

Published: 22 Sep 2017

This third data release from the VISTA Kilo-degree Infrared Galaxy Public Survey VIKING of images, source lists and a catalogue covers all of the highest quality data (images and single-band source lists) taken from November 2009 to March 2015. The release contains 736 VISTA images, of which 662 have coverage in all five VIKING near-infrared filters, 647 with deep co-adds in J, and an additional 74 with at least two filters. These 736 fields cover a total area of 1104 square degrees.

Call for Proposals for Period 101

Published: 31 Aug 2017

The Call for Proposals for observations at ESO telescopes in Period 101 (1 April 2018 – 30 September 2018) has been released. Please consult the Period 101 document for the main news items and policies related to applying for time on ESO telescopes. All technical information about the offered instruments and facilities is contained on ESO webpages that are linked from the Call. The proposal submission deadline is 12:00 CEST 28 September 2017.

Period 101 Changes in ESO Scientific Categories A and B

Published: 30 Aug 2017

Astronomers applying for time in Period 101 should note that the Observing Programmes Committee (OPC) scientific subcategories belonging to Categories A and B have been redefined. In addition, Category A is now called "Cosmology and the Intergalactic Medium" (previously "Cosmology") while Category B has been renamed "Galaxies" from "Galaxies and Galactic Nuclei". The full updated list of A and B subcategories is available on the OPC Categories page and in the ESOFORM User Manual.

ESO Postdoctoral Fellowships

Published: 28 Aug 2017

ESO’s prominent postdoctoral fellowship programme in both Garching (Germany) and Santiago (Chile) offers outstanding early-career scientists the opportunity to further develop their independent research programmes. From exoplanets to cosmology, observational, theoretical and fundamental astrophysics, these are all areas where ESO Fellows can benefit from a highly dynamic scientific environment, at some of the most advanced ground-based telescopes in the world.
