MUSE Wide Field Mode Adaptive Optics Science Verification

Published: 18 May 2017

GALACSI is part of the Adaptive Optics Facility (AOF), and associated with the Deformable Secondary Mirror (DSM) and the 4 Laser Guide Star Facility (4LGSF). It defines an AO system developed to increase the performance of the MUSE instrument in Wide Field Mode, dubbed MUSE/AOF. Commissioning is proceeding and Science Verification is planned for August 2017, for which applications are invited.

Release of CO(2-1) Spectra from APEX Low-redshift Legacy Survey for MOlecular Gas

Published: 17 May 2017

The APEX Low-redshift Legacy Survey for MOlecular Gas ( ALLSMOG, PI J. Wagg) has observed the CO(2-1) line in a sample of 88 galaxies in the Local Universe (0.01 < z < 0.03). The ALLSMOG observations add information on cold molecular gas content of all sources in this sample and the spectra are available in the ALLSMOG Phase 3 release.

The New Web-based Phase 2 Tool

Published: 16 May 2017

A web-based replacement for the ESO Phase 2 observing preparation tool P2PP3, named p2, has been released. Starting from Period 99 (1 April 2017), p2 is being used for (designated) Visitor Mode observations at Paranal, with the exceptions of VIMOS and GRAVITY. The plan is to extend the tool to support Service Mode by the end of 2017.

Release of MUSE Deep 3D Data Cubes

Published: 15 May 2017

Deep 3D data cubes obtained with the Multi-Unit Spectroscopic Explorer (MUSE) in the wide field mode have been released from early data acquired in June – August 2014, plus the initial two periods of MUSE operations, P94 and P95 (October 2014 through September 2015). These deep cubes are now published via the ESO Science Archive as reduced data.The MUSE-DEEP data collection contains 209 cubes.

GRAVITY Commissioning Data Released

Published: 14 May 2017

The VLTI instrument GRAVITY providing phase-referenced optical interferometry was first commissioned in 2016 and commissioning continues in 2017. Selected targets have been observed to demonstrate the capabilities of the instrument, develop observing strategies and optimize the data reduction pipeline. These commissioning data have now been released and are available.

New Release of Gaia-ESO Spectroscopic Public Survey Data

Published: 13 May 2017

New reduced data products resulting from the Gaia-ESO (Gaia-ESO) Public Spectroscopic Survey are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility. This third data release (DR3) provides a catalogue containing photometry and derived quantities, together with the associated wavelength calibrated 1-d spectra of point-like sources obtained with FLAMES from 31 December 2011 to 19 July 2014, for 25533 unique targets. The release also contains updated versions of these spectra reduced with the Gaia-ESO iDR5 pipelines.

The Challenge of Distributed Science Operations

Published: 12 May 2017

ESA/ESO SCIOPS Workshop 2017 "Working together in support of science"
European Space Astronomy Centre (ESAC), Madrid, Spain, 17–20 October 2017

Science operations are becoming ever more complex and this 3rd ESA-ESO collaborative workshop will focus on the challenges that distributed science operations present to space- and ground-based projects, promoting the interchange of ideas and information between ESA, ESO and the broader community.

Period 99 Delta Call for VLTI Proposals

Published: 06 Apr 2017

ESO is issuing a Delta Call, inviting proposals for VLTI time in July–September (Period 99B) with the Auxiliary Telescopes. Owing to a combination of circumstances, approximately 150 hours have become available for specific baselines in the date range 14 July – 23 September 2017 (see accompanying table).

ESO Period 100 Proposal Submission Statistics

Published: 05 Apr 2017

The deadline for proposal submission for Period 100 (1 October 2017 – 1 April 2018) was 30 March 2017. 895 valid proposals were submitted, including 16 Large Programmes, of which one is a GTO Large Programme. The number of proposals for P100 is very similar to that of periods 91 (893), 92 (892), 93 (898), 94 (901), 98 (901) and 99 (887). This indicates a return to a steady situation following the peak observed in periods 95 (934), 96 (960) and 97 (1024), corresponding to the deployment of MUSE and SPHERE. The total time request also remained very similar to the steady state, with the total number of distinct scientists exceeding 3500.

Release of Pipeline-Processed PIONIER Data

Published: 04 Apr 2017

As part of the agreement between ESO and Institut de Planétologie et d'Astrophysique de Grenoble (IPAG) to offer the VLTI PIONIER instrument in Service and Visitor Modes for Periods 96 to 99, IPAG has committed to process the raw data and deliver calibrated visibility data (squared visibility amplitudes and closure phases) to the ESO Science Archive Facility.
