The Present and Future of Astronomy - A Critical Look at Hiring, Evaluation Processes, the Way we do Science, and our Role in Society

Published: 20 Dec 2021

In this online workshop, which will take place from 14 to 18 February 2022, ESO invites the astronomical community to discuss several important aspects related to the way science is done, together with professionals from different scientific and social disciplines. On the first day of the workshop, philosophers will lead a discussion of the scientific method and its use in the modern world while the use of metrics in evaluation processes and distribution of funds will be discussed in the following days. One day will be dedicated to mental health in research, a topic of primary importance especially after the severe restrictions on scientific life due to the COVID19 pandemic. Finally, the workshop will be closed with a discussion about the role of astronomy in society.

ESO Summer Research Programme 2022 Call for Applications Is Now Open

Published: 13 Dec 2021

After the marked success of the program in the last three editions, ESO has been working hard on the preparation for the 4th ESO summer Research Programme and is now ready to open the call for applications. The fully-funded program is open to all university students not yet enrolled in a PhD course.

The Messenger 185 is now available

Published: 10 Dec 2021

The latest edition of ESO's quarterly journal, The Messenger, is now available online. This Issue 185 completes the series of articles dedicated to the the ESO's Extremely Large Telescope mirrors by presenting the lightweight field stabilisation mirror M5. Further, readers will get acquainted with the specifics of a new instrument for the VLT: MAVIS, which will be a powerful synergistic complement to the ELT in the visible wavelengths range.

Results of the 2021 Paranal Service Mode User Satisfaction Survey

Published: 02 Dec 2021

The User Support Department again extends its thanks to all those Principal Investigators and their Phase 2 delegates who filled this year's online Paranal Service Mode User Satisfaction Survey. A total of 248 responses were received from the targeted campaign. As in the past, where possible, respondents who provided detailed comments have been contacted via e-mail. A summary report based on this latest User Satisfaction Survey is now available.

First Data Release of the ARO MASCOT Survey

Published: 01 Dec 2021

MASCOT (MaNGA-ARO Survey of CO Targets) is an ESO Public Spectroscopic Survey conducted with the 12m telescope at the Arizona Radio Observatory (ARO). It provides the community with CO(1-0) measurements of 187 galaxies at 0.03 < z < 0.1 and stellar masses of > 109.5 M, all selected from the SDSS-MaNGA survey. Through the SDSS-MaNGA data releases, all MASCOT targets have accompanying optical IFU observations and well-constrained (spatially resolved) quantities like stellar masses, star formation rates and metallicities. The first data release of the MASCOT Survey for is now available to the community through the Supplementary Material of the Data Release Paper as well as on the MASCOT website.

New Talk Series: ALMA Recounts of Cosmic Conundrums

Published: 26 Nov 2021

The European ARC network is launching the new virtual talk series "ALMA recounts of Cosmic Conundrums". In every talk of this series a major astronomical question is discussed. The invited speaker will describe the context of the question and then focuses on the ALMA contribution to the field, past and future. The aim of the series is to highlight the unparalleled contribution of ALMA to the broader astronomical landscape and to provide an outlook towards the future.

New Gaia-ESO Radial Velocity Catalogue Released (DR4.1)

Published: 25 Oct 2021

Gaia-ESO is a Public Spectroscopic Survey carried out with GIRAFFE and UVES on the VLT between 2012 and 2018. The survey targeted more than 100,000 stars, with 115,000 actually observed by the end of the survey. These stars are selected across all major components of the Milky Way, from halo to star-forming regions, with the goal of providing a homogeneous overview of their kinematics and elemental abundance distributions.

VVVX DR1.1 Published: Releasing the Entire Ks Time Series

Published: 20 Oct 2021

The VISTA Cycle 2 ESO Public Survey project -VVV eXtended- PI D. Minniti, P. Lucas, is carried out with VIRCAM on VISTA in the JHKs filters and covers a total of ~1540 deg2 of the southern Galactic plane. The VVVX DR1.1 complements DR1 by mainly providing i) the missing Ks time series and ii) the source lists generated from the pawprints published in DR1, which were observed between July 2016 and March 2018. The released data total about 9 TB. Science products generated from observations in the time interval from April 2018 to October 2019 are accessible in the already published DR2 release.

APEX Heterodyne Line Intensity Monitoring Is Now Online

Published: 15 Oct 2021

A new interactive Grafana dashboard has made publicly available with the relevant results of the line intensity monitoring program, part of the APEX observatory calibration plan. An automated data reduction pipeline has recently been developed by the APEX Sciops team to analyse the scans of reference CO and HCN transitions in pointing sources. This new interface allows PIs to access the database with all these calibration observations, irrespectively of which specific project the observation was taken on.

ESO Period 109 Proposal Submission Statistics

Published: 15 Oct 2021

The deadline for proposal submission for Period 109 (1 April 2022 - 30 September 2022) was 23 September, 2021. The number of submitted proposals for Period 109 was 878, similar to that in previous Periods, so the plateau in the number of submitted proposals observed since several years remains. On the VLT the most requested instrument was MUSE with 255 requested nights, followed by X-Shooter with 252 nights, UVES (138n), ESPRESSO-1UT (132n) and CRIRES (122n). HARPS on the 3.6-metre telescope was the most demanded instrument at La Silla, with a request of 154 nights.
