ESO Science Announcements

Instrumentation Developments

Published: 26 May 2015

Recent developments of the Adaptive Optics Facility (AOF) project and the use of a laser comb for improved wavelength calibration have been announced.
The 4 Laser Guide Star Facility (4LGSF) achieved first light with the first of the laser guide star units on VLT UT4; see Announcement. The components of the AOF will be installed later this year and commissioned in 2015 and 2016.
The laser frequency comb installed on HARPS has completed an intense first commissioning phase. A velocity precision of better than 5 cm s-1 was obtained on a single laser comb exposure, improving to better than 2 cm s-1 on combining exposures. See Announcement for more details.

ALMA Early Science Cycle 3 Submission

Published: 25 May 2015

The submission of proposals for the ALMA Early Science Cycle 3 closed on 23 April 2015. The entire process went smoothly and without any problems. The number of proposals reached the record number of 1582 for a total of 9037 hours of 12-m array time; a total of ~2100 hours is available for observations. This compares to a total of 1382 proposals in Cycle 2. The fraction of proposals from European PIs was 42%. More details of the submission statistics are available.

Release of the ArTéMiS Data Reduction Package

Published: 24 May 2015

The submillimetre wide field bolometer camera ArTéMiS was successfully re-commissionned in July 2014 on APEX. ArTéMiS data can now be reduced using the BoA package. Dedicated ArTéMiS data reduction scripts are now available and the required receiver parameter files. Alternative data reduction scrips in IDL will be released in the near future.

New User Guide for Archival Reduced Data Products

Published: 23 May 2015

The Archive Science group has now published a user guide providing a description of the reduced data products that can be browsed and downloaded from the dedicated Phase 3 query forms of the Science Archive Facility. The user guide contains an overview of the data types, a description of their reduction/calibration levels and instructions on how to browse and access these products.
