GRA4MAT Narrow Off-Axis Mode / First Observations of Beta Pic b

Published: 03 Apr 2023

The Beta Pic dataset was obtained on 3 February 2023, in the course of the ESO-led development of a new GRA4MAT narrow off-axis mode. This new mode allows an observer to specify small offsets where to point MATISSE, with respect to the fringe tracking target. This mode is very similar to the dual on-axis mode of GRAVITY that was successfully applied to exoplanet spectroscopy. It will be offered to the community in the Call for Proposals for Period 112.

2023 Users Committee Meeting and Poll

Published: 31 Mar 2023

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 20 and 21 April 2023. During the UC meeting updates from ESO and feedback from the user community are exchanged and openly discussed. Each year one topic is explored in more detail and this year the Special Topic session is dedicated to Archive Science.

ELT MORFEO Instrument Passes Preliminary Design Review

Published: 31 Mar 2023

The Multiconjugate adaptive Optics Relay For ELT Observations (MORFEO, previously known as MAORY), an upcoming instrument for ESO’s Extremely Large Telescope (ELT), has recently passed its preliminary design review. MORFEO’s adaptive optics system will use special sensors to measure the blurring effects of the Earth’s atmosphere, correcting them with deformable mirrors. This will allow astronomers to get an unprecedented view into the Universe, offering detailed observations of distant galaxies and stars at the centre of the Milky Way.  

ALMA: New Targets for Science Verification of Band 1

Published: 31 Mar 2023

ALMA observations in Band 1 will be offered from Cycle 10. The science verification targets chosen for Band 1 are Orion KL and W51. The observations of these targets demonstrate the imaging and spectral scan capabilities in Band 1. The data are planned to be taken with about 20 antennas and will be released for public use. More information about the Band 1 science verification observations can be found here.

Sixth European ALMA Regional Centre Community Assembly

Published: 31 Mar 2023

The European ALMA Regional Centre invites European ALMA users to a virtual community assembly on April 17 at 11:00 CEST, in connection with the Cycle 10 call for proposals. At this meeting, more information will be provided on the procedures for Joint Proposals with other facilities, including the European Southern Observatory's Very Large Telescope, the Space Telescope Science Institute's James Webb Space Telescope, and the National Radio Astronomy Observatory's Karl G. Jansky Very Large Array.

2023 Release of VLT/VLTI Instrument Data Reduction Software Packages

Published: 30 Mar 2023

The annual public release of ESO VLT/VLTI instruments data reduction software packages is scheduled for end of May 2023. Please note that the new pipeline packages will be released for the following operating systems: Fedora 34, 35, 36, 37; Scientific Linux 7; CentOS 7; macOS 11, 12, 13.

Galaxy Transformation Across Space and Time - The 3rd Australia-ESO Meeting

Published: 30 Mar 2023

Galaxies transform throughout their lifetimes as a result of internal processes, interactions with other galaxies, their environments, and the cosmic web. The interplay of these processes alters the distribution of properties used to characterise the galaxy population. Understanding the impact and relative importance of the interplay of these processes is critical to galaxy evolution as whole.This conference will aim at connecting observations and simulations of galaxy transformations across cosmic time.

A Decade of ESO Wide-field Imaging Surveys

Published: 30 Mar 2023

With the end of VIRCAM@VISTA operations (first light June 2008, decommissioned March 2023) and OmegaCam@VST becoming a hosted telescope (first light Oct 2011, now managed by INAF), a decade of targeted wide-field imaging at ESO is coming to an end. Both instruments were largely dedicated to public imaging surveys, which have amassed a total of nearly 60,000 hours of telescope time. To commemorate these milestones, ESO organizes a 5-day workshop that reviews the legacy left by these instruments and summarizes the variety of scientific impact that these imaging surveys have on a wide range of research topics in astronomy, both in galactic and extra-galactic science.

ESO Period 112 Proposal Submission Statistics

Published: 30 Mar 2023

The deadline for proposal submission for Period 112 (1 October 2023 - 31 March 2024) was 28 March 2023: 895 valid proposals were submitted, of which 37 are Large Programmes.  On the VLT, the most demanded ESO instrument was MUSE with a request of 425 nights, followed by ESPRESSO with 347 nights and X-Shooter with 257 nights. HARPS/NIRPS on the ESO 3.6-metre telescope was the most demanded instrument at La Silla, with a combined request of 297 nights.
