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 m_B=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.

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).

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.

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).

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.

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.

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.

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.

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.

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.
