3 mai 2018: ALMA, the Atacama Large Millimeter/submillimeter Array, has reached an important milestone with the publication of the 1000th peer-reviewed paper using ALMA data. The paper was Spatial variations in Titan's atmospheric temperature: ALMA and Cassini comparisons from 2012 to 2015 by Alexander E. Thelen et al. — which presents a detailed investigation of the atmospheric temperature of Saturn's largest moon, Titan. The data behind the work of Thelen et al. was originally taken to help calibrate the telescope and have been available since 2013. ALMA data is archived online, meaning many discoveries by different researchers can be made from a single observational programme, or from data taken for an entirely different purpose, as is the case here. The full range of papers presenting observations and discoveries using ALMA data is also available online from the ESO telbib database [1]. The ALMA bibliography is jointly maintained by the librarians at ESO and ...

19 avril 2018: ESO has signed a contract with VDL ETG Projects B.V. (the Netherlands) for the manufacture, assembly, testing and delivery of the Segment Support Mechanics for the primary mirror of ESO’s Extremely Large Telescope (ELT). The segment supports together act as the backbone of the primary mirror, holding each of the 798 mirror segments in place. Sensors and actuators monitor and control each segment’s shape and position to very high accuracy. The contract was signed by Harrie Schonewille, Managing Director of VDL ETG Projects, Willem van der Leegte, President VDL and Xavier Barcons, Director General of ESO, at a ceremony at ESO Headquarters in Garching, Germany on 19 April 2018. When completed, the ELT’s primary mirror (M1) will be 39 metres in diameter and will consist of 798 hexagonal mirror segments. The hexagonal shape means that a common support structure can be used for all segments. Each segment will be connected ...

12 mars 2018: At its meeting on 7 March 2018, ESO Council decided to clarify the status of Brazil’s current relationship with the Organisation, for the benefit of both Brazil and ESO and their respective astronomical communities. Brazil’s accession to ESO was unanimously approved by ESO Council on 21 December 2010. To support Brazil in the period before ratification was completed, the Accession Agreement contained a series of interim arrangements. These offered, among others, the possibility for Brazilian industries to participate in ESO calls for tender (for contracts awarded after ratification), and for astronomers in Brazilian institutes to apply for observing time for ESO’s telescopes on the same basis as those from ESO Member States. The Accession Agreement was approved by the National Congress of Brazil on 14 May 2015, however, the conclusion of the accession process is still pending. Noting that the completion of the Accession Agreement is unlikely to happen in ...

12 mars 2018: ESO has signed a contract with the engineering and construction company Abengoa Chile to build the ELT Technical Facility at ESO’s Paranal Observatory in northern Chile. This new facility will host the assembly and maintenance facilities for the mirrors of ESO’s Extremely Large Telescope (ELT), as well as all the coating, washing and stripping facilities needed to coat and maintain the reflectivity of the mirrors. The primary mirror of the ELT will consist of 798 separate reflective segments [1]. At the ELT Technical Facility, the polished segment assemblies will be coated and integrated with the edge sensors on the sides of each segment, to detect the position of each segment relative to its neighbours [2]. Once the telescope is complete and in operation, each segment of the primary mirror will need recoating every 1.5 years to ensure its cleanliness and reflectivity. As there are 798 segments, the most efficient way ...

8 mars 2018: The latest survey of peer-reviewed scientific papers published during 2017 has shown that ESO remains the world’s most productive ground-based observatory. Astronomers used observational data from ESO facilities to produce an all-time high of 1085 refereed papers last year. This is the first time in ESO’s history that the number of refereed articles published by the ESO users community has exceeded 1000 papers in a single year. The largest contribution to the total is the 629 papers credited to ESO in 2017 that used data acquired with either the Very Large Telescope (VLT) or the VLT Interferometer facilities on Cerro Paranal. The three most productive VLT instruments in terms of papers are UVES, FORS2 and X-shooter, which featured in 133, 106 and 103 papers, respectively. The X-shooter and MUSE instruments saw large increases from the previous year, along with VIMOS, VISIR and the VLT Survey Telescope (VST). Data from the ...
