Imaging of Stellar Surfaces

Published: 19 Sep 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.

ESO Public Spectroscopic Surveys with ARO Telescopes

Published: 14 Sep 2017

ESO is offering the possibility of conducting Public Spectroscopic Surveys using the telescopes of the Arizona Radio Observatory, as part of an agreement with the University of Arizona. Public Surveys are observing programmes for which proposers collect and make publicly available, within a defined time, a fully reduced and scientifically usable data set that is likely to answer a major scientific question, and be of general use and broad interest to the astronomical community. The deadline for submitting Public Surveys proposals with the ESO ARO time is 19 October 2017.

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.

Limited Internet Connectivity on Paranal from 2–5 September 2017

Published: 29 Aug 2017

During early September, ESO's IT Department has scheduled a major upgrade of the ESO network architecture for the communications network in Chile. Operations on the Paranal site will be unaffected per se (including receipt of Target of Opportunity and Rapid Response Mode triggers), but during 2–5 September, there will be extended and intermittent periods where there will be no internet and email available on site (particularly relevant for Visiting Astronomers), and no scientific data transfer from Paranal to the Science Archive (relevant for Visiting Astronomers and Service Mode users).

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.

ESO Engineering and Technology Research Fellowship 2018

Published: 27 Aug 2017

The ESO Engineering and Technology Research Fellowship 2018 offers early-career researchers with a PhD degree in an engineering-related discipline, or in physics / astronomy with a strong technology content, the opportunity to take an active part in the very active ESO R&D projects for a minimum of 50% of their time, combined with a good deal of team spirit, curiosity and eagerness to learn.

ESO/NEON Observing School at La Silla

Published: 26 Aug 2017

Santiago and La Silla Observatory, Chile, 18 February – 2 March 2018

The ESO/NEON School is preferentially targeted to PhD students, advanced MSc's and early PostDocs. During two weeks of intense work the participants will have the chance to have hands-on experience of the full cycle from proposal preparation to data reduction. Students will have lectures on the basics of observing techniques and how to prepare observations for ESO telescopes in Santiago, and then go to the La Silla Observatory for three nights of observations with the NTT and Danish 1.54-metre telescopes. Full details on the School website.

VM Technical Losses

Published: 25 Aug 2017

Technical losses from VLT Visitor Mode observations have been analysed over four Periods (P95 – P98) and are reported here in response to a request from the Users Committee. The technical losses in Visitor Mode, and for global Service Mode and Visitor Mode in parenthesis are as follows on the VLT: UT1: 2.2% (3.4%), UT2: 2.5% (3.1%), UT3: 3.4% (4.6%), UT4: 1.2% (3.9%); on VLTI: 3.8% (7.9%).

Telluric Standard Stars Added to the X-shooter Data Collection

Published: 24 Aug 2017

1D spectra for telluric standard stars from the beginning of X-shooter operations in October 2009 until the present are now available as stand-alone science-grade spectra. About 30000 new 1D spectra have been added to the X-shooter data collection for a list of 1000 target stars; these numbers will grow as new spectra are added.
