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

Published: 13 Feb 2020

The VISTA EXtension to Auxiliary Surveys (VEXAS, 'Spiniello & Agnello, 2019, A&A, 630') project aims at providing photometric catalogues with the most uniform spatial coverage, in the multi-wavelength sky for various scientific uses, for example object classification (e.g. quasars, galaxies, and stars; high-z galaxies, white dwarfs), photometric redshifts of large galaxy samples and identification of exotic objects (e.g. extremely red objects and lensed quasars).


Publication of imaging products from the 'Accretion Discs in Halpha with OmegaCam - ADHOC' observing programme

Published: 12 Feb 2020

The ADHOC programme (096.C-0730(A) and 097.C-0749(A), PI G. Beccari) is equivalent to an OmegaCAM mini-survey targeting circumstellar discs in nearby Galactic star-forming regions. The scientific goal of this mini-survey is the study of the star formation history of several star-forming regions using deep, wide field, multi-band observations in the optical filters u, g, r, i and Hα, with depth reaching 21 AB mag in r. A total of eight star-forming regions in the Galaxy were observed.


New data release of spectra and catalogue from the VANDELS ESO Public Spectroscopic Survey

Published: 12 Nov 2019

VANDELS  is a deep Public Spectroscopic Survey targeting high-redshift galaxies in the UKIDSS Ultra Deep Survey (UDS) and Chandra Deep Field South (CDFS) survey fields using the VIMOS spectrograph. The goal is to obtain spectra with sufficient signal-to-noise ratio to derive stellar population ages, metallicities and outflows velocities from absorption line studies, allowing a detailed investigation of the physics of galaxies in the early Universe. Within an area of 0.2 deg2,  the survey aims at delivering ~2100 high signal-to-noise spectra of star-forming galaxies in the redshift range 1 < z < 7, with 85% of its targets selected to be at z >= 3, and passive galaxies in the redshift range 1 < z < 2.5.


Final imaging data release of the VST Public Survey VPHAS+

Published: 18 Oct 2019

The primary goal of the VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS+, PI J. E. Drew) is to collect single-epoch ugri broad-band and Hα narrow-band photometry across the southern Galactic Plane within the latitude range -5 < b < +5 with typical 5-sigma sensitivities for point sources down to 21 mag in Vega or fainter.


FEROS in-house processed data products not published since February 2019

Published: 18 Oct 2019

Archive users are informed that the generation of the in-house processed science data products for FEROS is currently suspended since February 2019. ESO is working on an improved version of the pipeline and the newly generated products will become available via the ESO archive interfaces in the incoming months. A new announcement will be posted once the publication of the reprocessed FEROS products is resumed.


First data release from the VISTA second cycle Public Survey VEILS

Published: 08 Oct 2019

The VISTA Extragalactic Infrared Legacy Survey (VEILS) 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. VEILS is covering 9 deg2 of the extragalactic sky over three fields: XMM-LSS, CDFS and ELAIS-S1.


Deep MUSE IFU cubes from observations of eight nearby edge-on galaxies released

Published: 26 Sep 2019

Deep IFU data cubes are now released for a sample of eight nearby edge-on galaxies. These galaxies were observed with the Multi-Unit Spectroscopic Explorer (MUSE) integral field unit at the VLT, under the ESO programmes 096.B-0054(A) and 097.B-0041(A) - PI S. Comeron - with the aim of studying the formation mechanism of the thick discs in these objects. The galaxies included in the current sample are: ESO 157-49, ESO 443-21, ESO 469-15, ESO 544-27, IC 217, IC 1553, PGC 28308 and PGC 30591.


UVES in-house processed data products not published since June 2019

Published: 26 Sep 2019

The PIs of ESO observing programmes with the Ultraviolet and Visual Echelle Spectrograph (UVES) are informed that the generation of the in-house processed science data products is currently suspended since June 2019. ESO is working in reprocessing the entire UVES data holding with improved algorithms and master calibrations. The newly generated products will become available via the ESO interfaces in the incoming months. A new announcement will be posted once the publication of the reprocessed UVES products is resumed.


Mapping the Milky Way bulge with VVV. The deep J,Ks catalogue based on PSF photometry is now released

Published: 22 Aug 2019

The Milky Way Bulge PSF Photometry project provides a comprehensive census of the stellar populations of the inner ~300 deg^2 of the Galaxy, using J and Ks band observations obtained with VIRCAM on VISTA from the VVV ESO Public Survey.


First data release from the VISTA second cycle Public Survey VINROUGE

Published: 09 Aug 2019

The primary goals of VINROUGE (Vista Near infra-Red Observations Uncovering Gravitational wave Events, PI N. Tanvir) are to locate and characterize the electromagnetic counterparts of gravitational wave discovered events. This is achieved through wide field, multi-filter (Y, J, Ks) imaging of the error regions with VIRCAM on VISTA. This first data-release contains imaging and catalogues obtained during the follow-up of three gravitational wave triggers during the second LIGO/Virgo science run (O2). These triggers were two black hole mergers GW 170809 and  GW 170814, and the Kilonova transient GW 170817. For the latter, the gravitational wave counterpart was detected and identified as a binary neutron star merger. The observations of the three different fields cover respectively 17 deg2, ~27 deg2 and 3.5 deg2.
