VMC DR5.1: Incremental high level products released for the Vista Magellanic Cloud Survey (VMC)

Published: 18 Jun 2020

This data release (DR5.1) is based on the observations acquired between February 2010 and October 2016 of 42 VMC survey tiles encompassing the whole Small Magellanic Cloud (SMC), the Magellanic Bridge and the Magellanic Stream components of the survey. The total sky coverage is ~40 deg2  in the SMC, ~ 20 deg2  in the Bridge and ~3 deg2  in the Stream. This release adds reduced and calibrated deep products (co-added tile images and related single band catalogues), together with a multi-band (YJKs) aperture matched, epoch merged source catalogue for more than 14.6 million sources, three multi epoch single band catalogues, a catalogue of variable sources (39406 records) and a PSF photometry catalogue. The total volume of this data release is about 166 Gb.

The data published within the VMC DR5.1 release are produced by the Wide Field Astronomy Unit (WFAU).


KiDS Data Release DR4.1

Published: 25 May 2020

The KiDS DR4.1 catalogue is an update of the DR4.0 catalogue which, due to a small bug in the alignment of the mask images during the multi-band catalogue production, has incorrect photometry flags for a small percentage of sources on 196 tiles. Those 196 updated tiles have been provided as KiDS DR4.1.


ESO Archive Science Portal 2.0 released

Published: 23 Apr 2020

The ESO Archive Science Portal allows browsing and exploration of archive content using an intuitive interactive user interface that supports iterative queries or by direct database and Virtual Observatory (VO) access using user scripts and VO-aware tools. The latest version, released on 23 April 2020, provides the features and improvements listed below.


Newly released MATISSE commissioning data of NGC 1068

Published: 03 Apr 2020

During the commissioning runs of MATISSE at VLTI in the second half of 2018 several astronomical targets were observed, in order to assess the scientific capabilities of the instrument and to optimise the observing strategies. This page provides links to selected data obtained during those runs, for both science and calibration targets.


First data release of the MUSE Analysis of Gas around Galaxies (MAGG)

Published: 18 Mar 2020

The MUSE Analysis of Gas around Galaxies project (MAGG, ESO programme ID: 197.A-0384, PI: M. Fumagalli) provides the community with high quality VLT/MUSE cubes centered on bright redshift z~3.5 quasars (Lofthouse et al. 2019). These absorbers were discovered in archival high-to-medium resolution spectra of the quasars collected, among others, with UVES and XSHOOTER.


New data release (DR5) of the ESO Public Survey VISTA Hemisphere Survey

Published: 17 Mar 2020

The VISTA Hemisphere Survey (VHS, ESO Programme ID: 79.A-2010, PI R. McMahon) is a wide area - multi band - near infrared survey, which when combined with other VISTA public surveys, will result in the coverage of the whole southern celestial hemisphere (Declination < 0; 20,000 deg2), to a depth 30 times fainter than 2MASS/DENIS in at least two filters (J and Ks), with a minimum exposure time of 60 seconds per filter and a median 5*sigma point source depth of AB = 20.8 and 20.0 in J and Ks filters respectively.


The final data release of the VISTA Kilo-degree Infrared Galaxy Public Survey: VIKING DR4

Published: 17 Mar 2020

The VISTA Kilo-degree Infrared Galaxy Public Survey (VIKING) is a wide area (covering a final area of 1350 sq. deg.), intermediate-depth (5-sigma detection limit J~21 on Vega system) near-infrared imaging survey, in the five broadband filters Z, Y, J, H, Ks. The sky coverage has maximum overlap with the Kilo-Degree Survey KiDS in the optical bands.


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.
