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.

VISTA Magellanic Survey Data Release 4

Published: 02 Apr 2017

The VISTA Magellanic Survey (VMC) aims at the determination of the spatially resolved star formation history and three-dimensional geometry of the Magellanic system, reaching sources below the oldest main-sequence turn-off with multi-epoch Ks mean magnitudes for pulsating variable stars. This new data release (DR4) is based on observations of twelve survey fields covering a total of about 18 square degrees, acquired between November 2009 and August 2013, with at least three visits per field in Y and J filters and 12 in Ks.
