First Data Release of the Burst Alert Telescope AGN Legacy Survey of Molecular Gas Fueling in Powerful Nearby AGN

Published: 03 Feb 2022

The APEX telescope has obtained CO(2-1) spectra for a sample of 165 hard-X-Ray-selected AGN galaxies detected in observations by the Burst Alert Telescope (BAT) onboard Swift. These observations, taken under the ESO programme id 198.A-0708, PI M. Koss, allow a statistical comparison of AGN and non-AGN dominated galaxies in the local Universe, for example from the ALLSMOG APEX survey. As this programme mainly aimed at observing a statistical sample of nearby AGN, many of the galaxies observed are well-known galaxies, and these Phase 3 data can provide a valuable total power measurement of the CO(2-1) emission which then can be combined with interferometric observations obtained with ALMA. Additionally, the BASS (BAT AGN Spectroscopic Survey) sample includes a variety of other ESO data products including hundreds of spectra with VLT/Xshooter, VLT/MUSE, and VLT/FORS2 with more information at the BASS survey website.

First Data Release from the ESO VISTA Public Survey - Southern H-ATLAS Regions in Ks-band (SHARKS)

Published: 01 Feb 2022

The Southern H-ATLAS Regions in Ks-band (SHARKS) is a deep Ks-band imaging survey conducted with the wide-field VIRCAM imager at the VISTA telescope. The project was granted 1200 hours of observing time under the ESO programme 198.A-2006 (PI H. Dannerbauer) as one of seven approved second cycle VISTA Public Surveys. It covers ~300 deg2, including large parts of the South Galactic Plane (SGP), GAMA-12h (G12) and GAMA-15h (G15) fields from the H-ATLAS survey, the largest Herschel program. The survey has been designed to provide the best possible counterpart identification for ∼90% of the sources detected at 0 < z < 3 by H-ATLAS, ASKAP, SKA and LOFAR; to produce a sample of strong lenses for cosmography studies; to study the evolution of the most massive structures in the Universe.

ESO@60: A Stairway to the Universe

Published: 21 Jan 2022

During the EAS2022 annual meeting in Valencia, Spain (27.06 – 01.07) the S14 symposium titled "ESO@60: a stairway to the Universe" will be held to celebrate the scientific achievements with the ESO facilities over the last 60 years. The scientific program will consist of six blocks of 1.5 hrs each, with each block covering a broad theme, starting from Extrasolar planets, Astrochemistry and Nucleo-synthesis, Stellar populations, Black holes, Cosmology & Galaxy evolution and then onto the ELT and the future. The registration and abstract submission are now opened, with abstract submission deadline on 01.03.2022. More information on sessions, keynote speakers, scientific organising committee and co-Chairs can be found on the S14 web page.

Message from the Director General

Published: 22 Dec 2021

Dear colleagues

Another unusual year has passed, although with a very positive balance for ESO and its community. Despite all difficulties associated with the pandemic, a lot was achieved. The observatories remained open for most or all of the year, with a focus on maximising the delivery of scientific data. Work on the ELT continued at a very good pace, new instruments are at various stages of development, CTA is taking shape, and a variety of scientific activities keep the link between ESO and its community as strong as ever. The special effort that we are all making through these difficult times is warmly appreciated by ESO’s governing bodies, whose unfailing support is a clear tribute to the impact that the ESO community has on worldwide astronomical research.

Phase 2 Observations Preparation for Observing Period 109

Published: 22 Dec 2021

With the release of the La Silla Paranal telescope schedule, the preparation of Service Mode (SM) observations (Phase 2) starts. The deadline for the submission of the Phase 2 material for Period 109 observations is 3 February 2022.

Period 109 Telescope Allocation

Published: 22 Dec 2021

The 109th Observing Programmes Committee (OPC) met online during November 2021. Based on the committee's recommendations to the ESO Director General, a total of 2093 (10-hour equivalent) nights of Designated Visitor Mode and Service Mode observations were allocated on the VLT/VLTIVISTA, the 3.6-metre and NTT, and APEX telescopes. The submission deadline for Phase 2 Service Mode observations is Thursday 3 February 2022; see the separate announcement for further details.

ALMA Cycle 9 Pre-Announcement

Published: 20 Dec 2021

The Joint ALMA Observatory (JAO) will start Cycle 9 observations in October 2022. A Call for Proposals (CfP) with detailed information on Cycle 9 is anticipated to be issued in March 2022 and the deadline for proposal submission will be in April 2022.  A pre-announcement has been issued highlighting aspects of the CfP to assist with early planning. More information on the Proposal Review Process, and full details on the offered capabilities can be found on the ALMA Science Portal. For additional questions regarding the Cycle 9 Call for Proposals, please visit the pre-announcement, the Q&A page or contact the ALMA Helpdesk.

SciOps 2022: Artificial Intelligence for Science and Operations in Astronomy

Published: 20 Dec 2021

The next Science Operations workshop, SciOps 2022, will be dedicated to Artificial Intelligence (AI) for science and operations in Astronomy and will take place on 16-22 May 2022 at the ESO Headquarters in Garching bei München. Building on the success of the previous series of similar events, this ESO/ESA workshop aims to facilitate the exchange of current developments and applications of AI-enabled technologies in science operations for space- and ground-based astronomical facilities.
