Message from the Director General

19 Dec 2023:

Dear colleagues

There is no doubt that 2023 has been a year with amazing progress at ESO, full of achievements and ending with a very positive forward look. We did have our fair share of difficulties, but it is undeniable that thanks to the commitment of our staff, the engagement with the community and the support from our Member States, many successes were achieved.

Opening for the Position of La Silla Paranal Observatory Director

18 Dec 2023:

ESO is currently advertising the position of the La Silla Paranal Observatory Director. The La Silla Paranal Observatory (LPO) provides and operates some of the world's largest and most advanced observational facilities at three sites in Northern Chile. La Silla hosts the 3.6-m telescope, the New Technology Telescope (NTT), and a number of hosted telescope projects. Cerro Paranal is the home of the Very Large Telescope, the VLT, the VLT Interferometer (VLTI), the VISTA survey telescope, and several Hosted Telescope projects. Paranal Observatory will further be responsible for the operation of the ELT at Cerro Armazones and the southern array of the Cherenkov Telescope Array Observatory (CTAO). APEX, the Atacama Pathfinder Experiment, is a hosted sub-mm telescope project located on the high-altitude site of Llano Chajnantor. The LPO division further works in close collaboration with the Data Management and Operations (DMO) division which is responsible for the off-site operations and user support of LPO in the framework of an integrated end-to-end system, maintaining the archive facility and its data holdings as a powerful resource, both scientific and operational. The LPO Director is a Division Head at ESO and reports to the Director of Operations.

Call for Applications for the 6th ESO Summer Research Programme

17 Dec 2023:

After the great success of the program in the last five editions, ESO is delighted to announce that the call for applications for the 6th ESO Summer Research Programme is now open. This fully-funded program is available to students in STEM fields who have not yet started a Ph.D. program and have completed at least two years of their degree.

First Announcement of Workshop ‘New Heights in Planet Formation’

17 Dec 2023:

This is the first announcement of the workshop ‘New Heights in Planet Formation’, to be held at ESO – Garching between 15 and 19 July 2024. In the past decade, facilities such as ALMA and VLT/SPHERE have transformed the field of planet formation, enabling both moderate resolution statistical disk surveys and high resolution imaging studies of disks. Today this field is driven by observations, and it seems to be continuing along this path with JWST and the many recently accepted Large Programs at different facilities. Theory and models are faced with the task of explaining much more complex scenarios of disk evolution, planet formation, planet-disk interaction. This workshop will bring together observers with expertise in different wavelength regimes, theorists, and modellers, to review the state of the art, pin-point the main open questions, and explore new venues.

Registration and Abstract Submission now Open for the Workshop "The Promises and Challenges of the ALMA Wideband Sensitivity Upgrade"

17 Dec 2023:

As previously announced, the workshop 'The promise and challenges of the ALMA Wideband Sensitivity Upgrade' will take place at ESO - Garching from the 24th to the 28th of June, 2024. This upgrade constitutes the top priority of the ALMA 2030 roadmap. It consists of an increase of the instantaneous spectral bandwidth by as much as a factor of four, while retaining full spectral resolution over the entire bandwidth, thus resulting in increases of the spectral scan speed up to a factor of 50 for the highest spectral resolution. In addition, an upgrade of the full signal chain of ALMA – from the receivers and digitizers, all the way through to the correlated data – will result in increases in sensitivity for all observations.

First Data Release of HARPS Radial Velocity Catalog

12 Dec 2023:

The first public data release of the HARPS Radial Velocities Catalog contains measurements obtained from 2003 to 2023 with the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph installed at the ESO 3.6m telescope in La Silla Observatory (Chile). The catalog comprises 289843 observations of 6488 unique astronomical objects. A total of 282294 radial velocities are reported in this catalog and are obtained using the HARPS pipeline (typical precision of 0.5 m/s) and 288972 independent radial velocities that are measured on the H_alpha spectral line (typical error of around 300 m/s).

Second Data Release from the VISTA Second Cycle Public Survey VEILS

04 Dec 2023:

The VISTA Extragalactic Infrared Legacy Survey (VEILS, PI: Banerji, Program ID:198.A-2005) is a deep J and Ks-band transient and wide-field survey being conducted using the VIRCAM camera with the primary goals of understanding the epoch of reionisation, the build-up of massive galaxies, and constraining the cosmological equation of state using both Type 1a supernovae and AGN dust lag measurements. The total VEILS surveyed area is 9 sq-deg of the extragalactic sky over three fields: XMM-LSS, CDFS and ELAIS-S1. The data acquisition for the VEILS survey was successfully completed in 2022 prior to the VIRCAM decommissioning

Results of the 2023 Paranal Service Mode User Satisfaction Survey

29 Nov 2023:

The User Support Department again extends its sincere thanks to all those Principal Investigators and their Phase 2 delegates who participated in this year's online Paranal Service Mode User Satisfaction Survey.  A total of 146 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.

Upcoming ESO or ESO-related workshops

The goal of this meeting is to encourage coordination in the communities who study the variable, transient and moving objects that the Vera C Rubin observatory’s LSST will discover vast numbers of, to figure out how best ESO’s facilities can provide the necessary follow up.

The workshop will take place at the ESO Headquarters in Garching near Munich and remotely (via MS Teams) from the morning of Tuesday, 23rd until noon of Friday 26th of January. Monday late afternoon/evening is planned for registration and get together.

 

ALMA is embarking on its most ambitious upgrade since its conception: the Wideband Sensitivity Upgrade (WSU). This upgrade constitutes the top priority of the ALMA 2030 roadmap. It consists of an increase of the instantaneous spectral bandwidth by as much as a factor of four, while retaining full spectral resolution over the entire bandwidth, thus resulting in increases of the spectral scan speed up to a factor of 50 for the highest spectral resolution. In addition, an upgrade of the full signal chain of ALMA – from the receivers and digitizers, all the way through to the correlated data – will result in increases in sensitivity for all observations. ALMA Band 2, the flagship ALMA upgrade project being led by ESO, will be the first receiver to exploit this new, wide bandwidth.

The aim of this workshop is to widely present the upgrade and engage the community by showcasing the science that will be enabled in the upcoming years, during which some changes on scientific operations are expected due to the extent of the upgrade, deployment, and commissioning activities. At the same time, ESO will also solicit input from the ALMA community that will be used to inform priorities during the commissioning phase.

 

Planet-forming disks can nowadays be probed with unprecedented detail thanks to facilities, such as ALMA at sub-millimeter wavelengths or high-contrast imaging instruments in the near-infrared such as the VLT/SPHERE instrument. In the past decade these facilities have transformed the field of planet formation enabling both moderate resolution statistical disk surveys and high resolution imaging studies of disks.

Today the field is driven by observations, and it seems to be continuing along this path with JWST upcoming results and the many recently accepted Large Programs in the field of planet-formation that are ongoing at different facilities. Theory and models are faced with the task of explaining much more complex scenarios of disk evolution, planet formation, planet-disk interaction. 

This workshop aims to bring together observers with expertise in different wavelength regimes, theorists, and modellers, to review the state of the art, pin-point the main open questions, and explore new venues.
