First data release from the GALACTICNUCLEUS survey

Published: 06 May 2021

The goal of GALACTICNUCLEUS survey, ESO Large Programme 195.B-0283, PI Rainer Schödel, is to build a single-epoch high angular resolution (0.2”) source catalogue of the Galactic Centre in the near infrared bands J,H,Ks.


Release of pipeline processed ESPRESSO 1D spectra products

Published: 29 Apr 2021

This data release provides access to reduced scientific data obtained with ESPRESSO. This instrument is a highly-stabilised fibre-fed echelle spectrograph that can be fed with light from either a single or up to four Unit Telescopes simultaneously. It is installed at the incoherent combined Coudé facility of the VLT. 


New spectra, images, and transient catalog of the PESSTO public survey (DR4)

Published: 24 Mar 2021

A new release of the Public ESO Spectroscopic Survey for Transient Objects (PESSTO) is available, including spectra and images from its ePESSTO extension, and the delivery of a new transient catalogue, globally covering 7 years of observations, from April 2012 to April 2019, for a total of 45GB.

This new release brings to 2323 the number of observed supernovae and optical transients, with calibrated 1D spectra for 2314 of them, doubling the number of objects previously published (1168 in the previous version).

Also doubled is the number of selected key targets (now 337) that were scheduled for follow-up time-series EFOSC2 optical spectroscopy, so to monitor the supernovae at the extremes of the known population e.g. the most luminous, the faintest, the fast declining, etc. The total number of spectra for the key targets is 3748, including the SOFI spectra taken for the brightest ones. SOFI imaging (broad-band JHKs) was nearly always taken when SOFI near infra-red spectra were taken.

Data are available via the ESO Science Portal or programmatically.

For more details on the observing strategy, the data reduction, calibration, and quality, along with a table of the selected key targets, and the description of the catalogue, please refer to the comprehensive release description.

Note: an updated version of the PESSTO multi-epoch photometry catalogue published in DR3.1 is expected by the summer.


First data released from the project 'INvestigating Stellar Population In RElics (INSPIRE)'

Published: 24 Mar 2021

The INSPIRE project is an ESO Large Programme (ID: 1104.B- 0370, PI: C. Spiniello) which uses X-Shooter (in UVB, VIS, NIR bands) to spectroscopically follow up 52 red ultra Compact Massive Galaxies selected from the KiDS VST ESO Public Survey. The goals of INSPIRE (Spiniello et al. 2021aSpiniello et al. 2021b) is to obtain the first catalogue of spectroscopically confirmed relics in the redshift range 0.1<z<0.5, bridge the gap between the three local confirmed relics and the high-z red nuggets, use the final statistic on confirmed relics to put a stringent constraint on the predictions from simulations on the initial burst of star formation in galaxies.


Second data release of the VISTA EXtension to Auxiliary Surveys (VEXAS)

Published: 18 Mar 2021

The VISTA EXtension to Auxiliary Surveys (VEXAS, Spiniello & Agnello, 2019, A&A, 630) project aims at building wide and spatially homogeneous  multi-wavelength catalogues (from X- ray to radio) providing reference magnitudes, colors and morphological information for a large number of scientific uses. Currently the VEXAS catalogue is the widest and deepest public optical-to-IR photometric and spectroscopic database in the Southern Hemisphere, comprising more than 90 million objects with reliable photometry measured in at least one of the VISTA infrared bands, two of the WISE bands and three optical bands.


ESO Science Data Products standard version 7 published

Published: 04 Mar 2021

Version 7 of the ESO Science Data Products standard is now published; highlights of the revisions are:


Fourth - and final - data release of the Spectroscopic Public Survey VANDELS

Published: 04 Feb 2021

The fourth and final data release of the deep VIMOS survey of the CANDELS UDS and CDFS fields, VANDELS, is now available in the ESO Science Archive Facility.


First Data Release from the VST survey of Early-type GAlaxieS (VEGAS)

Published: 01 Feb 2021

VEGAS is a deep multi-band (u'g'r'i') imaging survey of bright (MB<-21mag) early-type galaxies in the local volume within 54 Mpc/h carried out with OmegaCam on the VLT Survey Telescope (VST, Capaccioli et al., 2005; see also the VEGAS website). Observations are based on the VST Guaranteed Time Observation assigned to the Italian National Institute for Astrophysics under programme ID runs: 089.B-0607(A), 090.B-0414(B,D), 091.B-0614(A), 092.B-0623(B,C,D), 094.B-0496(D), 095.B-0779(A), 096.B-0582(B), 097.B-0806(A,B), 098.B-0208(A), 099.B-0560(A), and 0100.B-0168(A).


High-Resolution MUSE data of the inner region of NGC 7130 released

Published: 10 Dec 2020

The Seyfert starburst galaxy NGC 7130 was targeted for commissioning and science verification of the MUSE Narrow Field Mode, in programmes 60.A-9100(K) and 60.A-9493(A), P.I. Marja Seidel.


New data release (DR4) from the Gaia-ESO Spectroscopic Public Survey

Published: 10 Dec 2020

The new data release from the Gaia-ESO Public Spectroscopic Survey (GES) DR4 delivers about 190,000 stacked, quality-controlled, 1-d spectra (R between 18000 and 54000) of 114,500 unique stellar targets. These stars were observed with GIRAFFE and UVES from 31.12.2011 to 26.01.2018, during the entire time execution of the survey. These targets were selected from all the major structural components of the Milky Way: bulge, thick and thin discs, halo, including open star clusters of all ages and masses. The 1-D spectra from GES DR4 augment or update the spectra published in the previous data releases, which included observations up to July 2014 (~44000 spectra for ~25000 objects).

A catalog of radial velocities is being finalized and will be released in the subsequent data release (DR4.1), together with the 1D stacked spectra for additional ~600 unique targets.

The final data release from the Gaia-ESO survey containing the catalog with the measured stellar parameters will be released later in 2021.

The total volume of GES DR4 is 32 GB. These data are available via the Science Portal, and programmatically. More information is available in the accompanying release documentation. Instructions on how to read or display data in the ESO Science Data Products tabular data format can be found in the 1D spectrum data format help page.
