Galaxy Clusters At Vircam (GCAV) is a survey belonging to the second cycle of ESO VISTA Public Surveys. It is aimed at observing 20 clusters of galaxies covering in total ~30 deg2 in the infrared Y, J, and Ks bands. It will mainly explore galaxy evolution over a large, and largely unexplored, diversity of cluster environments. The DR1 release concerns 9 clusters and contains tile images and related source lists from data collected over the period from October 2016 to the end of September 2017. For two clusters, RXCJ1514.9-1523 and RXCJ2129.6+0005 with complete observations during periods P98 and P99, deep stacks in Y, J and Ks filters are also released, as well as merged catalogues containing aperture matched photometry in the filter bands of the deep stacks.

The Next Generation Transit Survey (NGTS) is a ground based exoplanet survey designed to detect Neptune and super-Earth sized planets orbiting around bright stars, using the transit method. The NGTS facility consists of 12 fully-robotic 20cm f/2.8 telescopes located on ESO ground in Paranal. Each telescope has a 2.8x2.8 deg² field of view and is equipped with a custom filter with a bandpass of 520-890nm, which increases sensitivity to late-K and early-M stars.

This data release provides 1D spectra of 103 individual afterglows that were observed with the XSHOOTER spectrograph within 48 hours of the GRB trigger. The data release includes a few late-time host observations also for completeness. The total collection of spectra represents all GRB afterglows that have been followed up with XSHOOTER before March 31st, 2017. This date marks the end of the XS-GRB legacy follow-up program. Redshifts have been measured for 97% of these sources, covering a redshift range from 0.059 to 7.84, hence this dataset provides a unique resource to study the ISM across cosmic time.

ESO’s Archive Science Portal provides an intuitive yet very powerful way of browsing, searching and downloading reduced science-ready data. Since the initial rollout three months ago, it has already been visited by more than approximately 1700 users (as inferred from the count of distinct IP addresses). Based on user feedback a new view mode has been implemented as a central new feature in addition to the already existing sky view. It allows users to inspect, at a glance, the multi-dimensional query space in up to seventeen 1D distributions. They include physical parameters like sensitivity and signal-to-noise ratio, alongside more traditional ones such as Programme ID or instrumental setup. Users can easily interact with any list or histogram to add or remove search constraints and to build up rather complex queries in a progressive fashion.
