News from ESO's Quality Control

Published: 23 Sep 2026

Quality Control at ESO has seen changes with respect to its tools and the data organization and processing with the reduction pipeline recipes (EDPS). The overhaul of quality control software and data processing was driven in parts to augment the real-time science data assessment and OB grading with up-to-date calibrations.

When Galaxies Meet: Zooming into the Multi-Scale Physics of Interaction and Mergers across Cosmic Time (GALMEET), Garching near Munich, 14 - 18 June 2027

Published: 23 Sep 2026

This ESO workshop will explore the extreme environments and physical processes associated with galaxy interactions and mergers across cosmic time. Galaxy encounters often give rise to some of the most spectacular star-forming events, rapid accretion and coalescence of supermassive black holes, and powerful feedback phenomena capable of transforming galaxies completely. The workshop will revisit the recent advancements in this key area of galaxy evolution research, from both observational and theoretical perspectives, and envision future directions enabled by the next-generation multi-wavelength wide-field facilities and surveys.

Comparison of Panel Review and Distributed Peer Review at ALMA

Published: 25 Aug 2026
Since 2021, ALMA has used a distributed peer review model instead of traditional panel-based review. In a recent study, John Carpenter and Andrea Corvillon analysed more than 20,000 proposals and over 160,000 individual reviews over 13 ALMA cycles (Cycles 0–12) to examine whether the statistical patterns of proposal evaluation changed. Overall, the study finds that the outcomes of distributed peer review are statistically consistent with those of traditional panel review. You can read a summary of the result on the ALMA website and the paper accepted for publication in PNAS.

ESO Fellowship Programme 2026 / 2027

Published: 21 Aug 2026
ESO's prestigious postdoctoral fellowship programme in both Garching (Germany) and Santiago (Chile) offers outstanding early-career scientists the opportunity to further develop their independent research programmes. From exoplanets to cosmology, observational, theoretical and fundamental astrophysics, these are all areas where ESO Fellows can benefit from a highly dynamic scientific environment, at some of the most advanced ground-based telescopes in the world. Do watch ESOCast 165 to hear what previous ESO fellows have to say about the fellowship programme or watch the virtual tour to ESO's premises from 2020 or 2021 where young scientists could ask questions about the fellowship programme.
