NEAR Science Demonstration: Call for Proposals

Published: 10 Jul 2019

ESO, in collaboration with the Breakthrough Initiatives, has modified the Very Large Telescope mid-infrared imager (VISIR) to greatly enhance its ability to search for potentially habitable planets around both components of the binary Alpha Centauri, part of the closest stellar system to the Earth. Apart from this specific goal, a variety of science cases will benefit from the enhanced sensitivity and point spread function contrast. The community is invited to participate in this opportunity to carry out unique science and thus to demonstrate the scientific capabilities of this modified instrument. A Call for Proposals has been issued and the community is invited to submit proposals for the NEAR science demonstration using the new Phase 1 web interface.

Period 104 Telescope Allocation

Published: 04 Jul 2019

The 104th Observing Programmes Committee (OPC) met on 14-16 May 2019. Based on the committee's recommendations to the ESO Director General, a total of 1248 (8-hour equivalent) nights of Visitor Mode and Service Mode observations were allocated on the VLT/VLTIVISTAVST, the 3.6-metre and NTT, and APEX telescopes. The submission deadline for Phase 2 Service Mode observations is Thursday 1 August, 2019; see the separate announcement for further details.

Phase 2 for Observing Period 104

Published: 04 Jul 2019

With the release of the telescope schedule, the preparation of Service Mode (SM) observations (Phase 2) starts. The deadline for the submission of the Phase 2 material for Period 104 is 1 August 2019.

New Issue of The Messenger Online

Published: 03 Jul 2019

The latest edition of ESO's quarterly journal, The Messenger, is now available online. In issue 176 you will find out about Astronomy in Ireland, the work of the ESO Users Committee, Science Verification results using MUSE's Narrow Field Mode, and how KMOS is being used to study low-mass galaxies across several epochs of cosmic time. This issue also contains articles presenting science highlights from ALMA, an article from ESO fellows and students outlining their development of an outreach programme, reports from workshops, and a tribute to Gustav Tammann.

Data Release: The VVV Infrared Astrometric Catalogue (VIRAC) - version 1

Published: 01 Jul 2019

With this data release, the VISTA VVV survey (179.B-2002) publishes the VVV near-infrared Astrometric Catalogue (called VIRAC). This contains proper motions of stars measured during five years of observations (from 2010 to 2015). The catalogue contains ZYJHKs band-merged magnitudes (single epoch, wherein the Ks magnitude is a mean value) and proper motion measurements for 312 587 642 unique sources detected in the multi-epoch imaging campaign covering 560 deg2 of the Milky Way bulge and southern disc. VIRAC includes 119 million high quality proper motion measurements, out of which 47 million have statistical uncertainties below 1 milliarcsecond yr-1. The VIRAC photometric calibration and astrometric reference frame are both derived from the 2MASS Point Source Catalogue.
