ESO Science Announcements

Announcement of 3mm VLBI in ALMA Cycle 5

Published: 19 Jan 2017

It is expected that phased ALMA will participate in some Global 3mm VLBI Array (GMVA) observations during ALMA Cycle 5 (1 October 2017 – 30 September 2018); see the full announcement for further details. Any GMVA proposal requesting phased ALMA during Cycle 5 must be submitted by the 1 February 2017 deadline; see the proposal call .

Availability of ALMA Solar SV Data

Published: 19 Jan 2017

The latest release of ALMA Science Verification (SV) data will contain observations of the Sun obtained during the Solar commissioning campaigns in 2014 and 2015. The release contains mosaics and single pointing observations in quiet and active solar regions at Band 3 and 6 with the 12-metre, 7-metre and total power arrays. The data are available under ALMA Science Portal SV.

Period 99 Telescope Allocation

Published: 17 Jan 2017

The 99th Observing Programmes Committee (OPC) met on 15–17 November 2016. A total of 1044 (10-hour equivalent) nights of Visitor Mode and Service Mode observations were allocated on the VLT/VLTI, VISTA, VST, the 3.6-metre and NTT and APEX telescopes. Of these, 193 nights were allocated to filler programmes. The submission deadline for Phase 2 Service Mode observations is 9 February 2017, see announcement.

Angra do Heroísmo, Azores, Portugal, 27 August – 2 September 2017

In the coming years a range of ground- and space-based facilities will gather an unprecedented amount of high-quality data in observational astrophysics and cosmology. These will allow open cosmological problems, e.g., nature of dark matter, dark energy, inflation and neutrino masses, to be tackled, all of which require new physics. In order to fully exploit these datasets, the interplay of a broad range of expertise, encompassing theory, phenomenology, high performance computing, data analysis and instrumentation, is required.

Early Stages of Galaxy Cluster Formation (GCF2017)

Published: 12 Jan 2017

Mergers, Proto-clusters, and Star Formation in Overdense Environments
ESO Headquarters, Garching, Germany, 17 – 21 July 2017

Proto-clusters, high redshift galaxy clusters, and merging clusters represent the initial stages in the formation of largest gravitationally-bound structures in the Universe. (Proto-)cluster assembly via mergers and accretion has a decisive impact on the subsequent cluster evolution, and is thus an important process to understand. The aim of  GCF2017 is to discuss cluster formation over the last ten billion years, from its beginnings to the present day.
