ALMA Science Archive Remote Visualisation with CARTA

03 Mar 2021:

The Cube Analysis and Rendering Tool for Astronomy (CARTA), a new image visualisation and analysis tool designed for ALMA, VLA, and SKA pathfinders, has been integrated into the ALMA Science Archive (ASA). Now all 500,000+ science FITS files in the ALMA archive can be previewed using CARTA (Cycle 0 excluded).

2021 Users Committee Meeting and Poll

03 Mar 2021:

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 on 27 and 28 April 2021.

CRIRES+ Sees First Light on the Very Large Telescope and Is Now Offered for Period 108

03 Mar 2021:

The installation of the upgraded CRIRES at the VLT, also known as CRIRES+, was completed in late February last year, with first light expected to happen shortly after. However, the COVID-19 pandemic forced the delay of the Commissioning for almost a year. With the ramping up of the Paranal Observatory in November 2020, the CRIRES instrument was reactivated on the 4th of December 2020 and the commissioning activities took place starting on January 18th, 2021 with 8 nights and February 18th with 6 nights. Due to the deadline for the call for proposals only the results of Commissioning 1 could be included and the instrument is offered during Period 108 with a subset of modes.

New Issue of The Messenger Online

02 Mar 2021:

The latest edition of ESO's quarterly journal, The Messenger, is now available online. Issue 182 is a special one dedicated to the instrumentation programme for ESO’s Extremely Large Telescope (ELT). It features articles detailing the status of the ELT instrumentation programme, as well as presentations of each instrument individually. This issue also contains science results based on SINFONI and MUSE, as well as profiles from two ESO fellows describing what sparked their interest in astronomy and their respective paths to ESO. The issue closes with a tribute to Nichi D’Amico, ESO Council representative for Italy, who passed away in September 2020.

ESO Proposal Anonymisation

25 Feb 2021:

Period 108 marks the full deployment of the Dual-Anonymous Peer Review (DAPR) in the evaluation of proposals for observations at ESO telescopes. Applicants must formulate the scientific rationales of their proposals following the anonymisation rules and examples described in this link, which also gives a detailed description of the DAPR paradigm. While Period 106 was used as a dry run, both to make the community aware of the upcoming implementation of DAPR and to test its practical, procedural and policy aspects, from Period 108 proposal anonymisation is mandatory. Failure to abide by the DAPR rules may lead to disqualification of the proposal.

Call for Proposals for Period 108

25 Feb 2021:

The Call for Proposals for observations at ESO telescopes in Period 108 (1 October 2021 – 31 March 2022) has been released. Please consult the Period 108 document for the main news items and policies related to applying for time on ESO telescopes. All technical information about the offered instruments and facilities is contained on ESO webpages that are linked from the Call. The proposal submission deadline is 12:00 CET 25 March 2021.

Fourth - and Final - Data Release of the Spectroscopic Public Survey VANDELS

05 Feb 2021:

The fourth and final data release of the deep VIMOS survey of the CANDELS UDS and CDFS fields, VANDELS, is now available in the ESO Science Archive Facility. The VANDELS survey (Programme id 194.A-2003, PI L. Pentericci and R. McLure) started data acquisition in November 2014 and was completed in March 2018 before the VIMOS decommissioning. It delivers high signal-to-noise (range: 10 -100), medium resolution (R~600) optical spectra (4800-10000 Å) for galaxies in the UKIDSS Ultra Deep Survey (UDS) and Chandra Deep Field South (CDFS) survey fields. The total area covered is 0.2 degree2.

First Data Release from the VST survey of Early-type GAlaxieS (VEGAS)

03 Feb 2021:

VEGAS is a deep multi-band (u'g'r'i') imaging survey of bright (MB<-21mag) early-type galaxies in the local volume within 54 Mpc/h carried out with OmegaCam on the VLT Survey Telescope (VST; see also the VEGAS website). Observations are based on the VST Guaranteed Time Observation assigned to the Italian National Institute for Astrophysics under programme ID runs: 089.B-0607(A), 090.B-0414(B,D), 091.B-0614(A), 092.B-0623(B,C,D), 094.B-0496(D), 095.B-0779(A), 096.B-0582(B), 097.B-0806(A,B), 098.B-0208(A), 099.B-0560(A), and 0100.B-0168(A).

Upcoming ESO or ESO-Related Workshops

VIMOS, the VIsible Multi-Object Spectrograph, was decommissioned in March 2018. After 15 years of operations, VIMOS has amassed over 9700 hours of science data, mostly devoted to spectroscopic surveys of galaxies across cosmic time. This also marked the completion of the two last VIMOS Public Surveys: VANDELS and LEGA-C. To commemorate this milestone, we are celebrating a 5-day workshop to review past and current spectroscopic surveys on galaxy evolution (both with ESO and non-ESO instruments), as well as to explore future surveys that will be soon enabled by new MOS and IFU facilities.

Proto-clusters, high redshift galaxy clusters, and merging clusters represent the initial stages in the formation of largest gravitationally-bound structures in the Universe. Forming via mergers and accretion, (proto-)cluster assembly has a decisive impact on their subsequent evolution, and is thus an important process to understand. The aim of GCF2021 is to discuss cluster formation over the last roughly ten billion years, from its beginnings to the present day, with a particular focus on the progress and developments since the first GCF meeting in 2017.

The vision for ALMA's future development is described in the ALMA Development Roadmap. In order to implement this vision a series of three workshops has been envisioned, in conjunction with corresponding working groups defining the appropriate scientific and technical specifications. Following the first two workshops held in 2020 to discuss potential correlator and digitizer upgrades that will realize the ALMA 2030 vision, we plan to complete the workshop trilogy with an ALMA Front-End Development Workshop, entitled The ALMA 2030 Vision: A next generation of front-end receivers". This workshop will be held online, in the week of 27-30 September 2021.

The goal of this workshop is to bring together the galactic, extragalactic, and high-redshift communities, both theorists and observers, with the final goal of fostering fruitful discussions and new collaborations on the formation of the central regions of galaxies. Amongst the main topics to be discussed are: chemo-dynamical properties of the MW bulge, observed properties of bulges and link to formation scenarios, bulges in a cosmological context, clumpy discs, mergers and bulge formation at high redshifts, formation and evolution of bulges from a theoretical perspective.
