Workshop: Science with APEX

Published: 12 Oct 2019

Schloss Ringberg, Germany, 2–5 February 2020 

In the last two years, APEX has been significantly improved by upgrades of the antenna itself as well as by the commissioning of new instruments almost continuously covering the range from 157 to 732 GHz. These improvements have been most visible at the highest frequencies, which have now become standard operations. Two new wide-field bolometer cameras are also expected to come online in the next 2 years. The science with APEX workshop will bring together APEX users and other interested scientists working on a wide range of exciting results covering the Solar System to distant galaxies in the early Universe. Workshop participants will have the opportunity to present new science results and to look into new science opportunities for the next years.

ESO-ESA Joint 2020 Science Workshop: New Science in the Multi-messenger Era

Published: 10 Oct 2019

ESO Headquarters, Garching, Germany, 14–18 September 2020 

The detection in 2017 of electromagnetic light from a pair of merging neutron stars first identified in gravitational waves ushered in a new era for astronomy. This multi-messenger era is rapidly becoming established with the identification of gravitational wave sources and astrophysical neutrinos occurring at ever-increasing rates, although joint electromagnetic detection remains challenging. This meeting will seek to review the recent dramatic progress in this field, evaluating the science from the current LIGO/VIRGO O3 run that will complete before the workshop. It will also look to what future ESO (E-ELT, next-generation VLT instruments) and ESA (ATHENA, LISA, THESEUS) projects contribute to this nascent field. 

Data Release: Fifth Data Release from VMC Public Survey

Published: 08 Oct 2019

The VISTA Magellanic Survey (VMC) led by Principal Investigator Maria-Rosa Cioni aims to determine the spatially resolved star formation history and the three-dimensional geometry of the Magellanic Cloud system. The sensitivity in Y, J and Ks filters has been designed to reach sources below the oldest main-sequence turn-off point of the stellar population and through the multi-epoch coverage to measure accurate Ks mean magnitudes for pulsating variable stars like RR Lyrae and Cepheids. Data Release 5 (DR5), published on 01 Aug 2019, provides the complete set of observations covering the Small Magellanic Cloud field (~40 square degrees), it also includes tiles from the bridge (~20 square degrees) and the stream (3 square degrees) for a total of 42 VMC survey tiles.

Data Release: Deep MUSE IFU Observations of Nearby Edge-On Galaxies

Published: 06 Oct 2019

Deep IFU data cubes are now released for a sample of eight nearby edge-on galaxies: ESO 157-49, ESO 443-21, ESO 469-15, ESO 544-27, IC 217, IC 1553, PGC 28308 and PGC 30591. These galaxies were observed with the Multi-Unit Spectroscopic Explorer (MUSE) integral field unit at the VLT with the aim of studying the formation mechanism of the thick discs in these objects. These deep science data cubes are characterised by long exposure times, typically three hours, and careful removal of the sky background from the target exposures rather than offset skies. 

Data Release: VISTA Public Survey VEILS DR1

Published: 04 Oct 2019

The VISTA Extragalactic Infrared Legacy Survey (VEILS) is one of the Cycle 2 VISTA Public Surveys. It is a deep J- and Ks-band transient and wide-field survey that has the following goals: understanding the epoch of reionisation, the build-up of massive galaxies, and constraining the cosmological equation of state using both Type 1a supernovae and AGN dust lag measurements. VEILS covers 9 square degrees of the extragalactic sky over 3 fields: XMM-LSS, CDFS and ELAIS-S1. This first data release (DR1) contains pawprint images (239 in J and 225 in Ks) and deep stacked pawprints (72 in total over the 3 cosmological fields), together with associated confidence maps and single-band J and Ks source lists. 

ESO/ESA Data Release: NACO and XMM Observations of the Galactic Centre

Published: 06 Sep 2019

Recent observations suggest that the supermassive black hole at the centre of our galaxy is going through a special accretion event. In the framework of the ESA/ESO agreement, coordinated observations with the Very Large Telescope and the XMM-Newton observatory were taken on the night of 31 August 2019. This joint near-infrared and X-ray monitoring effort aims at constraining the physical processes that regulate accretion by supermassive black holes and the subsequent variability in the emission of radiation. To facilitate a prompt and broad exploration of this rich dataset, the ESO data collected with the NACO instrument have been made publicly available at the ESO Science Archive Facility (under Programme ID 2103.B-5061). Further, the XMM-Newton dataset is also publicly available at the XMM-Newton Science Archive.

Call for Proposals for Period 105

Published: 30 Aug 2019

The Call for Proposals for observations at ESO telescopes in Period 105 (1 April – 30 September 2020) has been released. Please consult the Period 105 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 26 September 2019.

Call for Proposals for Period 105: Joint VLT-XMM Proposals

Published: 26 Aug 2019

By agreement with the ESA XMM-Newton Observatory, ESO may award up to 290 ksec (~ 80 hours) of XMM-Newton observing time. Similarly XMM-Newton may award up to 80 hours of ESO VLT observing time. Proposals that request different amounts of observing time on each facility should be submitted to the Observatory for which the greatest amount of time is required. This opportunity is offered yearly in odd periods, i.e., periods with a proposal submission deadline in September or October. Starting in Period 105, Target of Opportunity runs and "Triggered Observations" are possible via this cooperative programme, with some restrictions. Interested users should consult Section 4.9 of the Call for Proposals document.

ESO Fellowship Programme

Published: 24 Aug 2019

ESO’s prestigious 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. Do watch ESOCast 165 to hear what current ESO fellows have to say about the fellowship programme.

2nd ESO-Australia conference: The Build-up of Galaxies through Multiple Tracers and Facilities

Published: 22 Aug 2019

Perth, Australia, 17–21 February 2020 

By 2020, the first major results will be obtained from a huge variety of “pathfinder” facilities that are operating with entirely new types of survey instruments. These pathfinders have the common aim of untangling galaxy evolution physics, and so it is important that first science results are communicated across various disciplines. This is the main purpose of the second Australia-ESO conference, allowing us to start serious conversations about the future coordination of next-generation galaxy evolution surveys.
