New data release of MUSE data cubes of the Fornax3D Survey

Published: 25 Jan 2023

The Fornax3D survey is an integral field spectroscopic survey of the Fornax cluster's galaxies. This data release contains mosaiced IFS MUSE cubes with their white lamp images for the 31 galaxies brighter than mB=15 within the virial radius of the cluster. The total data volume is 121.5 Gb. The survey was conducted under the ESO programme 296.B-5054(A), PI M. Sarzi and E. Iodice, with MUSE at the ESO VLT in wide-field mode. This instrument configuration ensures a spatial sampling of 0.2×0.2 arcsec2, a wavelength coverage from 4650 to 9300 Å with a spectral sampling of 1.25 Å/pixel, and a nominal spectral resolution of FWHM = 2.5 Å at 7000 Å. The main science goals of the survey are to understand the assembly history of the Fornax cluster, the early-type galaxies and the formation of substructures in galaxies. For more information on the background and goals please consult the latest paper by Sarzi, Iodice et al. on the Messenger.

New data release from the APEX Large CO Heterodyne Outflow Legacy Supercam survey of Orion (ALCOHOLS) project

Published: 19 Dec 2022

This collection provides wide-field spectral line imaging data cubes (5 cubes, total volume: 11.50Gb) of the Orion A and B giant molecular clouds in the 12CO (J=3-2) line at a frequency of 345.795990 GHz from observations collected under ESO programme 094.C-0935, PI: T. Stanke, and the Swedish programme 094.F-9343. The data were obtained using the SuperCAM 64-pixel heterodyne array camera at the APEX telescope in December 2014. The cubes cover a total area of ~2.7 deg2 in the Orion A and B giant molecular clouds. The frequency axis includes the full spectral extent of the CO line detected in the area, including high-velocity line wings from protostellar molecular outflows. The data reveal a wealth of cloud structures and allow for an unbiased search for protostellar molecular outflows over a large portion of a star-forming cloud. A full presentation of the survey overview and data was published in Stanke et al. (2022, A&A 658, A178).

Release of pipeline-processed high-resolution imaging data obtained with SPHERE/IRDIS

Published: 14 Dec 2022

SPHERE (Spectro-Polarimetric High-contrast Exoplanet REsearch) is an extreme adaptive optics system and coronagraphic facility feeding three science instruments: IRDIS, IFS, and ZIMPOL. The primary science goal of SPHERE is imaging, low-resolution spectroscopic, and polarimetric characterization of extra-solar planetary systems. IRDIS, the infrared dual-band imager and spectrograph provides classical imaging (CI), dual-band imaging (DBI), dual-polarization imaging (DPI), and long slit spectroscopy (LSS) between 0.95 – 2.3 µm.

Second data release - DR2.0 - of the Large Programme MUSE Analysis of Gas around Galaxies - MAGG

Published: 17 Nov 2022

With this second data release, the large program "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~3-4.5 quasars (Lofthouse et al. 2020).

New data release of the Vista Magellanic Cloud Survey (VMC): YJKs imaging of the LMC and updated survey catalogues

Published: 26 Sep 2022

The ESO Public Survey project VMC, ESO program 179.B-2003, PI M. R. Cioni, targets the Magellanic Cloud system in three filters: Y, J and Ks. The main goals are the determination of the spatially resolved star formation history and study the three-dimensional geometry of the system.

Release of pipeline processed FORS2 spectroscopic 1D science products

Published: 20 Sep 2022

This data release provides access to reduced scientific 1D spectra obtained with FORS2, the visual and near-UV FOcal Reducer and low dispersion Spectrograph 2 on the VLT.

Data Release of the ESO-VLT Multi-Instrument Kinematic Survey of Galactic Globular Clusters

Published: 02 Aug 2022

This release provides stellar spectroscopy of galactic globular clusters in YJ band (1.0-1.35 μm), for a total of 5397 1-D extracted spectra in 30 clusters. The data was acquired using the K-band Multi Object Spectrograph (KMOS) under the ESO large program 193.D-0232, PI F. R. Ferraro.

New release - DR 4.1 - of the UltraVISTA/COSMOS2020 catalogues

Published: 30 Jun 2022

UltraVISTA (PIs J. Dunlop, M. Franx, J. Fynbo, O. LeFèvre, Programme ID 179.A-2005, 198.A-2003) is an ultra-deep near-infrared ESO Public Survey targeting the central region of the COSMOS field. This public survey started in April 2010 and has been completed during the VISTA Public Survey Cycle II in 2022.

First Light for GRAVITY Wide at the VLTI

Published: 08 Jun 2022

GRAVITY+ is the ongoing upgrade of GRAVITY and the Very Large Telescope Interferometer (VLTI) with wide-separation fringe tracking, new adaptive optics, and laser guide stars on all four 8-m Unit Telescopes (UTs), for ever-fainter, all-sky, high contrast, milliarcsecond interferometry. GRAVITY+ just reached its first milestone: GRAVITY Wide.

Fifth Gaia-ESO data release: astrophysical parameters of about 115000 stars

Published: 16 May 2022

Gaia-ESO is an ESO Public Spectroscopic Survey (under ESO Programme IDs: 188.B-3002, 193.B-0936, 197.B-1074; PIs: Gerry Gilmore & Sofia Randich) carried out with GIRAFFE and UVES on the VLT between 2012 and 2018. The survey targeted more than 100,000 stars, with 115,000 actually observed by the end of the survey. These stars are selected across all major components of the Milky Way, from halo to star-forming regions, with the goal of providing an homogeneous overview of their kinematics and elemental abundance distributions.
