ESO Science Announcements

Workshop: The Very Large Telescope in 2030 - Second Announcement

Published: 21 Apr 2019

ESO, Garching, Germany, 17–21 June 2019 

ESO is organising a special workshop to discuss the future science uses of the VLT when the ELT will be operational. The workshop will consist of invited reviews and contributed talks to discuss potential development paths for VLT and VLTI. Discussion topics will include new and improved VLT and VLTI instrumentation, potential modifications or upgrades to the facilities, changes in the operations model and synergies with other facilities. We encourage presentations of this nature and will schedule ample time for contributed talks.

Workshop: A Synoptic View of the Magellanic Clouds - VMC, Gaia and Beyond

Published: 19 Apr 2019

ESO, Garching, Germany, 9–13 September 2019 

More than 60 years ago, the Magellanic Clouds provided crucial impetus for the construction of large telescopes in the Southern hemisphere and the foundation of ESO. This workshop will provide a fertile forum for shaping the future of research related to the Magellanic Clouds by showcasing state-of-the-art results based on advanced observational programmes as well as discussions of expectations and projections in anticipation of highly multiplexed wide-field spectroscopic surveys (e.g., 4MOST, MOONS) which will come online in the 2020s. This conference also marks the quincentenary of Ferdinand Magellan's arrival in the southern hemisphere during his circumnavigation of the Earth. Very recently, in 2018, there was also Henrietta Leavitt's 150th birthday and the 110th anniversary of her discovery of the period-luminosity relation among Magellanic Cloud Cepheids.

ALMA2019: Second Announcement

Published: 17 Apr 2019

Cagliari, Italy 14–18 October 2019

Registration has now opened for the next ALMA-wide science conference and the list of invited speakers has been published at the meeting website.
ALMA is the world’s most sensitive facility for millimetre/submillimetre astronomical observations, and will soon be fully operational in all of the originally planned bands. Since its first observations, ALMA has routinely delivered groundbreaking scientific results that span nearly all areas of astrophysics. Science topics at this conference will include all fields of astronomy, from cosmology and galaxies in the distant Universe, nearby galaxies and the Galactic Center, interstellar medium and star formation in our Galaxy, astrochemistry, circumstellar disks, exoplanets, solar system, stellar evolution, and the Sun. As in previous editions of the conference series, we expect to discuss the scientific priorities for the implementation of the ALMA Development Roadmap.

Workshop: ESA/ESO SCIOPS 2019 - Working Together in Support of Science

Published: 15 Apr 2019

ESAC, Madrid, Spain, 19–22 November 2019 

ESA/ESO SCIOPS WORKSHOP 2019 – Working Together in Support of Science – Cross Facilities Collaboration in the Multi Messenger Era

The upcoming ESA/ESO SCIOPS 2019 Workshop will take place at ESAC and will address the following areas:

  • collaboration between large scientific teams in the multi-messenger era;
  • how space- and ground-based observatories communicate their transient and observational capabilities, and can prepare and adapt them to provide scientists with access to time and data for multi-messenger programmes;
  • cultural and policy changes needed to enable multi-facility time allocation, prioritisation of observations, publication of information on upcoming observations and data sharing;
  • tools, services and standards to support coordination between facilities for the selection and publication of targets by survey facilities, coordination and publication of follow-up observations among observatories, as well as for publishing, searching, analysing and visualising data;
  • tools and services to support collaboration between teams.

ALMA Cycle 7 Call for Proposals

Published: 25 Mar 2019

The ALMA Cycle 7 Call for Proposals for scientific observations is open for submissions. ALMA Cycle 7 is currently scheduled from October 2019 to September 2020. Users of any nationality or affiliation are invited to to submit proposals before the deadline at 15:00 UT on 17 April 2019. It is anticipated that 4300 hours will be available on the 12-metre array time and 3750 hours on the Atacama Compact Array (ACA) (also known as the Morita Array), including a supplementary call. Proposals must be prepared and submitted using the ALMA Observing Tool (OT), which is available for download from the ALMA Science Portal. Proposals will be assessed by competitive peer review by a single international review committee.
