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 (M_B<-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 in May 2022.

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.

Second Data Release from the Galaxy Clusters At Vircam (GCAV) ESO VISTA Public Survey

Published: 08 Dec 2020

Galaxy Clusters At Vircam (GCAV) is a survey (programme 198.A-2008, PI M. Nonino) belonging to the second cycle of ESO VISTA Public Surveys. It is aimed at observing 20 massive galaxy clusters covering in total ~30 deg2 in the infrared Y, J, and Ks bands. Those clusters have also been observed in many ground- and space-based programmes (e.g. CLASH, RELICS, HFF/ BUFFALO). The survey will mainly explore galaxy evolution over a wide, and still largely unexplored, diversity of cluster environments.

Second Data Release of the Fornax Deep Survey (FDS): catalogue of sources and additional imaging covering 27 sq. degree on the Fornax cluster

Published: 11 Nov 2020

The second data release from the Fornax Deep Survey with VST projects is now available on the ESO archive and it is accessible to the community via the Science Portal, programmatically, and via the Catalogue Query Interface. This data release follows the publication of the refereed paper by Cantiello et al. (2020).

This second release provides ugri-bands photometric and morphological parameters for 1.7 million sources over the ∼21 square degree area of the Fornax Cluster centered on the bright central galaxy NGC 1399. Additionally, photometric and morphological parameters in the gri-bands are provided for 3.1 million sources located on a wider area of ∼27 square degrees which extends to the direction of the galaxy NGC 1316, also in the Fornax cluster.

The catalogues contain sources detected down to a 5-sigmamagnitude limits which correspond to 24.1mag, 25.4mag, 24.9mag, 24.0mag in u-, g-, r-, and i-band, respectively (calculated for point sources). The total volume of the released catalogs is 1.2Gb.

The second release also increments the previous image release with ~7.5Gb of images and weight maps for the FDS field n. 8 that have been processedand calibratedby the AstroWISE.

More information about the release content can be found in the accompanying documentation.

ESO complete in-house re-processing of 20 years of UVES 1D spectra

Published: 26 Oct 2020

As part of ESO’s efforts to offer science data products to its community via the ESO science archive facility, all the spectroscopic data acquired since the beginning of UVES operations at the VLT from March 2000 to March 2020, i.e. 20 years, have been reprocessed. Whenever possible, 1D spectra have been stacked at the OB level. The master calibrations associated with the science data before March 2015 have been reprocessed for better quality and consistency. Due to this reprocessing, some of the early science products not available before are now provided. All 1D spectra products are available from the ESO archive, have quality control plots and associated 2D extracted spectral images.

New band-merged source catalog released by the VVV survey

Published: 09 Oct 2020

A new version of the VVV VISTA Public Survey source catalog is now available from the ESO Archive. The imaging data in the ZYJHKs bands from which the source catalogue is extracted are acquired under ESO programme 179.B-2002 before the 26th of September 2015.

APEX-LABOCA flux map of M83 released

Published: 08 Oct 2020

This new data release includes a flux map at 870 μm for the galaxy M83 (NGC 5236). It is obtained from the combination of the observations taken with the Large APEX Bolometer Camera (LABOCA) at APEX under the ESO programme id 081.C-0827(A), PI A. Lundgren, between 2008-06-19 and 2008-06-30.

The total exposure time of the flux map is 10.5 hours, it has a signal to noise ratio of 47 in the galaxy central region, while the inner spiral arms are detected with a signal to noise ratio of more than 3. The atmospheric window of 870 μm, in which LABOCA operates, provides the opportunity to study the dust in the interstellar medium and the grain size distribution.

More information is available in the release documentation. The data can be accessed via the ESO Science Portal or programmatically.
