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.

Vacancy for Data Scientist at ESO

Published: 24 Mar 2019

A new position for a Data Scientist is open for applications until 31 March. The role of the Data Scientist will will be to develop and apply innovative deep learning techniques to object classification in the ESO and ALMA Science Archives. With a user base of thousands of scientists, the archives are a rich and powerful resource for the astronomical community worldwide. The Data Scientist will be responsible for designing, building and training a system based on deep learning object classification techniques with the goal to automatically classify astronomical images and spectra to open up innovative ways for scientists to use the data.

Users Committee Meeting 2019

Published: 24 Mar 2019

The Users Committee (UC) represents ESO's astronomical community at large and acts as an advisory body to the ESO Director General on matters related to the performance, scientific access, operation and user interfaces to the La Silla Paranal Observatory and ALMA. The annual meeting of the UC is scheduled at ESO Headquarters on 29-30 April 2019. During the UC meeting updates from ESO and feedback from the user community are exchanged and openly discussed. Each year, the UC meeting has one session dedicated to a special topic – in 2019 the special topic is on the community use of Public Surveys data. The meeting webpage includes a record of the last meeting with recommendations that will be discussed in April.  

ESO Publication Statistics 2018

Published: 23 Mar 2019

In 2018, for the second time in a row, the total number of data papers published by the ESO users community exceeded the 1000 mark, almost exactly matching the record high of the previous year  (2017: 1090; 2018: 1093). In total, over 15 000 data papers have been published since 1996 (the year the ESO Telescope Bibliography started). In 2018, the number of papers using data from the VLT/VLTI, the ESO survey telescopes VISTA and VST, as well well as APEX were slightly below those of 2017, while data from the La Silla observing site led to even more data papers than in recent years*. The largest increase occurred for ALMA (taking into consideration only data obtained during European observing time), which generated 24% more papers than in 2017.

Messenger 175: The 4MOST Issue

Published: 22 Mar 2019

The latest edition of ESO's quarterly journal, The Messenger, is now available online. Issue 175 is dedicated to 4MOST. 4MOST is a wide-field spectroscopic survey facility that is under development for VISTA at Paranal and which will be able to simultaneously obtain spectra of ~2400 objects distributed over an hexagonal field-of-view of 4 square degrees. This issue of The Messenger contains important information about the facility itself, its scientific operations and survey strategy, which will be particularly useful to teams preparing to submit survey proposals for the facility. In addition, there are articles outlining the strategies and science goals for each of the ten 4MOST Consortium Surveys targeting both Galactic and extragalactic science.
