Period 101 Telescope Allocation

Published: 02 Feb 2018

The 101st Observing Programmes Committee (OPC) met on 14–16 November 2017. A total of 1000 nights (10-hour equivalent) of Visitor Mode and Service Mode observations were allocated on the VLT/VLTI, VISTA, VST, the 3.6-metre and NTT, and APEX telescopes. The outcome of the time allocation was communicated to the Principal Investigators of the 899 proposals submitted for Period 101 on 21 December 2017. The submission deadline for Phase 2 Service Mode observations was on 1 February 2018.

ALMA Programme Scientist

Published: 01 Feb 2018

The position for European ALMA Programme Scientist is open for applications. The Programme Scientist will serve as the primary contact between the ALMA Observatory, the European ALMA Support Centre and the European astronomical community with respect to the scientific capabilities, mission and exploitation of the ALMA facility. They will be responsible for ensuring that the European share of the observatory and its future development will enable ALMA to meet scientific requirements. Additionally the Programme Scientist will monitor the scientific performance of ALMA operations and its ability to carry out forefront science.  

Release of VLT/VLTI Instrument Data Reduction Software Packages

Published: 01 Feb 2018

The annual public release of ESO VLT/VLTI instruments data reduction software packages is scheduled for April 2018. Please note that the updated pipeline packages will be released for the following operating systems: Fedora 24–27, CentOS 7, Scientific Linux 7 and macOS 10.10–10.13. In addition to the release of data reduction pipelines in April, some instruments with pipelines under active development have intermediate releases throughout the year. To get announcements of new pipeline releases, please send an email or visit the VLT Instrument Pipelines webpage.

Workshop: A Revolution in Stellar Physics with Gaia and Large Surveys

Published: 31 Jan 2018

Warsaw University Library, Warsaw, Poland, 3–7 September 2018

The era of Gaia-enabled revolutions in almost all areas of astrophysics has started. In particular, and crucially, Gaia's exquisite astrometry and photometry combined with data from other large stellar surveys (ground- and space-based) will allow major progress in our understanding of stellar physics. The workshop will focus on the advances in our understanding of stellar physical processes made possible by combining the astrometry and photometry of Gaia with data from other large photometric, spectroscopic, and asteroseismic stellar surveys. Asteroseismology, in particular, has been essential to probe the interiors of stars. These combined data will permit detailed studies of stellar physics to a level that is unprecedented in the history of stellar astrophysics. More details are available on the workshop page or by email. The registration and abstract submission deadline is 15 April 2018.

Phase 2 for Observing Period 101

Published: 22 Dec 2017

The allocation of ESO telescope time for Period 101 (1 April – 30 September 2018) is expected to be emailed in the week of 18 December 2017. With the release of the telescope schedule, preparation of Service Mode (SM) observations (Phase 2) starts. The deadline for the submission of the Phase 2 material for Period 101 observations is 1 February 2018.
