ESO Period 99 Proposal Submission Statistics

Published: 19 Oct 2016

The deadline for proposal submission for Period 99 (1 April – 1 October 2017) was 29 September 2016. 883 valid proposals were submitted, including 22 Large Programmes, of which one is a GTO Large Programme. The number of proposals for P99 is the lowest received in the last 7 periods. The time request also went down, while the number of proposals per PI remained constant. The number of normal proposals is slightly increased from P98, while Large and GTO proposals decreased. The time request decreased for almost all telescopes.

Getting Ready for ALMA Band 5 – Synergy with APEX/SEPIA

Published: 18 Oct 2016

ESO Workshop, Garching, Germany, 1–3 February 2017

The frequency range from 160 to 210 GHz covered by ALMA Band 5 is one of the least explored to date. This band is expected to be offered in ALMA Cycle 5, but has already been extensively used in the SEPIA instrument on APEX since 2015. Important science topics covered by Band 5 include the 183 GHz H2O line, a wide range of dense molecular gas tracers (HCN(2-1), HNC(2-1), HCO+(2-1), etc), CO(2-1) at 0.077<z<0.414, [C I] and high-J CO lines in high redshift objects, and eventually the [C II] line at z>8.

Star Formation from Cores to Clusters

Published: 17 Oct 2016

ESO Workshop, Vitacura, Santiago, Chile, 6–9 March 2017

This Workshop aims to bring together astronomers pursuing a variety of strategies in answering the question: "What constitutes a prototypical low-mass star forming region from core to cluster scales?". This question refers specifically to the formation of low-mass stars, but also involves higher-mass stars, starless cores, brown dwarfs and planet formation simultaneous with low-mass star formation, and related topics. The workshop will feature observational and theoretical/simulation studies in pursuing a comprehensive understanding of low-mass star forming regions.

GRAVITY Science Verification Completed

Published: 16 Oct 2016

The VLTI K-band beam combiner instrument GRAVITY successfully completed its second run of Science Verification (SV) in September 2016 (10–18 September). Most programmes have been completed or mostly completed (i.e., the SV team assessed that sufficient data were collected to reach the proposal goal).

Third Public Release of the Kilo-Degree Survey (KiDS) Now Available

Published: 14 Oct 2016

KiDS is one of the ESO Public Surveys carried out with OmegaCAM at the VLT Survey Telescope (VST). Once complete, 1500 square degrees will have been observed in four filters (u, g, r, i). As a weak lensing shear tomography survey, KiDS will also map the large-scale matter distribution in the Universe and constrain the equation of state of Dark Energy. Its secondary science cases include galaxy evolution and structure of the Milky Way.
