Science Announcements


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

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

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

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.

ALMA Cycle 8 Has Started

11 Oct 2021:

ALMA is very pleased to share the news that on the evening of 1 October, the first observations for Cycle 8 2021 were successfully completed and observing has continued since then. The data sets are currently being quality-assessed and some data have already been delivered to the respective principal investigators.

2021 ESO Studentships

11 Oct 2021:

The ESO research studentship programme provides an outstanding opportunity for PhD students to experience the exciting scientific environment at one of the world's leading observatories. ESO's studentship positions are open to students enrolled in a university PhD programme in astronomy or related fields. Students accepted into the programme work on their doctoral project under the formal supervision of their home university. However, they come to ESO to work and study under the co-supervision of an ESO staff astronomer for a minimum of six months and up to two years.

ELT M4 Adaptive Mirror Petals Completed

08 Oct 2021:

The largest adaptive mirror ever built, the M4 mirror for ESO’s upcoming Extremely Large Telescope (ELT), has reached an important milestone in its development: all six petal-shaped segments that make up the mirror are now completed. M4, the fourth mirror in the light path of the telescope, can change shape quickly and very precisely, and is a key part of the ELT’s adaptive optics system.

Second Imaging Data Release from the VISTA Cycle 2 ESO Public Survey VVVX

18 Sep 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. This second data release contains observations taken between April 2018 and October 2019. They consist of both multi-filter JHKs observations and time series Ks data with photometric limit reaching typically Ks=17.5 AB mag.

The Messenger 184 is Now Available

16 Sep 2021:

The latest edition of ESO's journal for science and technology, The Messenger, is now available online. Issue 184 opens with an article on the impact of satellite constellations to observatories and ESO’s role in supporting the astronomy community. Next our readers will find a report on the scientific prioritisation community poll that took place in 2020.

CONCERTO Commissioning Data Released

09 Sep 2021:

CONCERTO raw data from the commissioning runs on APEX between April and August 2021 have now been released. Selected astronomical targets were observed to demonstrate the capabilities of the instrument and optimize the observing strategies. These objects cover a range of science targets: the star forming region NGC6334 (Cat Paw Nebula, see also ESO announcement), the Crab nebula supernova remnant, the AS2UDSS deep field, and the galaxy cluster RXCJ1206. These relatively short integration data can be used to plan future observing programmes and, in some cases, for scientific work.

Upcoming ESO or ESO-Related Workshops

The detection and characterization of extrasolar planets is a field that has undergone rapid advancements in the past decades. As we push towards the detection of lower-mass planets around Sun-like stars via both direct and indirect techniques our understanding of the host star becomes increasingly important. This workshop aims to identify what aspects of our understanding of stellar properties are limiting our ability to measure and characterize extrasolar planets, to present new ideas on how to overcome them, and to develop new collaborations between researchers studying extrasolar planets and those studying the properties of the stars they orbit.

The primary goal of the workshop is to discuss the relevance of reproducible workflows in astronomy and potential pathways for the astronomical community. As part of the workshop, we will aim to share examples of reproducible work as well as tools and techniques for improving reproducibility and for mining astronomical data. We will discuss community guides, tools and white papers related to data sharing, reproducible workflows, data mining and big-data problems. This will include making recommendations for hiring and funding bodies that will aim to encourage open approaches and retain expertise in the astronomical community. We will organise groups to continue this work after the workshop is concluded to widen community participation.

Chilean based observatories have been leading the scientific research in several astronomical areas. This forum is organized around the highest impact science results in the last few years. We will show how these different observatories contributed to major advances in Astrophysics and we will put emphasis on the scientific involvement of the astronomers working at those observatories on those high impact results.

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, and formation and evolution of bulges from a theoretical perspective. The meeting is intended to be highly participative, with substantial time devoted to discussions to promote cross-disciplinary interactions and exchange of ideas. This ESO Workshop should set the basis for the study of galaxy bulges in the new decade.
