ESO Science Announcements

Survey on Non-Publishing ESO Programmes (SNPP)

Published: 04 May 2016

A recent study by Sterzik et al. 2015 (Messenger article) has revealed that the number of ESO observing programmes not leading to refereed publications is significant, exceeding 50%. This return rate applies also to highly ranked, fully completed programmes. Although this fraction is comparable to those measured at other large ground-based astronomical facilities, it is very important for ESO to identify the underlying reasons, in order to investigate possible avenues to increase the scientific return of its facilities.

First Light for the 4LGSF

Published: 02 May 2016

First light for the Four Laser Guide Star Facility (4LGSF) was achieved on 26 April 2016 (see the Release). The four 22-watt laser beams excite sodium atoms in the upper atmosphere to provide four point sources for adaptive optics systems to compensate the atmospheric turbulence. 4LGSF is an integral part of the Adaptive Optics Facility (AOF), which includes a deformable secondary mirror (DSM) and the GALACSI and GRAAL modules. The complete facility will gradually be commissioned over the next year and a half.


Application for ESO Studentships

Published: 29 Apr 2016

The ESO research studentship programme provides an outstanding opportunity for Ph.D. students to experience the exciting scientific environment at one of the world's leading observatories for a period of up to two years.

Phase 2 Ephermerides Generation for Moving Targets

Published: 29 Apr 2016

A new version of the Phase 2 page dedicated to the observation of moving targets has been released. This page offers a new web form for generation of ephemerides files directly in parameter file format (PAF) ready to be attached to an Observation Block (OB). The new ephemerides file generator in PAF format was developed at IMCCE in Paris, who kindly offered to host the web form for ESO Phase 2 observation preparation.

Period 97 Instrument Pipeline Packages Released

Published: 28 Apr 2016

From the start of Period 97 (1 April 2016), updated versions of all VLT/VLTI data reduction pipelines are publicly available. The pipelines are available on the VLT instrument pipelines page.

A mailing list has also been created so that users can subscribe to receive announcements of new pipeline releases. To join this mailing list, please send an e-mail to eso-pipelines-announce-join.
