This is the first data release, DR1 of the IFS deep cube obtained in the MUSE Ultra Deep Field (MUDF) as part of the Large Programme ID 1100.A-0528, PI M. Fumagalli.

This second data release (DR2) of the X-Shooter ESO Large Program 1104.B-0370, "INvestigating Stellar Population In Relics", INSPIRE, PI C. Spiniello, provides 1-D spectra for 21 new systems and new versions for the spectra of the 19 ultra-compact massive galaxies already released in DR1, to which the NIR band spectra have been added.

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).
