This first public data release (DR1) contains UVB and VIS X-Shooter spectra (wavelength coverage of 300-1020 nm) of 232 massive stars in the Large and Small Magellanic Clouds (LMC, SMC). All stars were observed in STARE Mode, using 0.8” and 0.7” slits for the UVB and VIS, respectively, resulting in a resolving power of ~6700 in the UVB and ~11400 in the VIS. The observations were spread on 102 different nights from October 2020 to Juli 2021 and include 129 LMC and 113 SMC stars. Both individual and co-added spectra are included in the release. Generally, individual exposures (INDIV1D) are available as ancillary files, and co-added spectra with UVB and VIS merged (COADD1D) as the main science spectra, except for some of the binaries, for which only the individual exposures are provided. </div> <div class="read_more_link" align="left"> <a href="/cms/eso-archive-news/First-data-release-from-the-Large-Programme-X-Shooting-ULLYSES-XShootU.html">Read more</a> </div> <br> <div class="clear"></div> </div> </div> </div> <div class="pr_box"> <h2 class="pr_headline"> <a href="/cms/eso-archive-news/new-data-release-from-the-apex-core-and-filament-formation-and-evolution-in-natal-environments-caffeine-project.html">New data release from the APEX 'Core And Filament Formation and Evolution In Natal Environments' (CAFFEINE) project</a> </h2> <div class="pr_lead"> <div class="pr_list_text"> <strong>Published: 15 Jul 2024</strong> <div class="teasertext"> <p>This collection contains imaging data products for the observing programme CAFFEINE whose data were acquired with the <a adhocenable="false" href="https://www.apex-telescope.org/ns/observing-run/observing/the-telescope/instruments/artemis/">ArTéMiS</a> camera at the APEX telescope from 2018 to 2022. The 48 imaged fields cover a total area of more than ~ 2.5 deg<sup>2</sup>, focused on the dense (AV > 10) parts of molecular clouds within about 3 kpc from the Sun. The released products include, per each field the 350 μm and 450 μm intensity maps with resolutions of 8” and 10” (half-power beam width), their related weight maps and multi-resolution H<sub>2</sub> column density maps. These datasets have been carefully calibrated and combined with Herschel/SPIRE data to recover large-scale emission that cannot be detected from the ground with ArTéMiS. The column density maps have been derived by including additional Herschel data at 160 μm and 250 μm and have a resolution ranging from ~8” in their denser inner parts (AV > 40) to 18.2” in the lower-density outer parts (AV < 40).

A recent overview of UltraVISTA can be found in <a href="https://zenodo.org/records/10150386">this presentation</a>. The sixth and last UltraVISTA data release, “DR6” or “Legacy”, comprises stacked images in YJHKs and NB118 narrow-band filters, as well as single-band and dual-mode source lists. The data release also contains a five-band merged catalogue, created from the individual Ks-selected source lists. The release is based on the observations carried out from December 2009 to March 2023, corresponding to 99,845 individual images. The observations obtained since the DR5 release are mostly in the Y-band “deep” stripes in order to bring them to the same depth as the previously observed “ultra-deep” stripes. Thus, in this release, the depth is nearly uniform over the full field for the broad-band YJHKs filters. This release also uses GTO data obtained in 2010 in the J and the NB118 filters in the “deep” stripes. </div> <div class="read_more_link" align="left"> <a href="/cms/eso-archive-news/sixth-and-last-release-of-ultravista-public-survey-data.html">Read more</a> </div> <br> <div class="clear"></div> </div> </div> </div> <div class="pr_box"> <h2 class="pr_headline"> <a href="/cms/eso-archive-news/release-of-muse-galaxy-groups-in-cosmos-magic-survey-datacubes.html">Release of the MUSE gAlaxy Groups In COSMOS (MAGIC) survey datacubes</a> </h2> <div class="pr_lead"> <div class="pr_list_text"> <strong>Published: 22 Apr 2024</strong> <div class="teasertext"> <p> The release of the <a adhocenable="false" href="https://www.eso.org/sci/facilities/paranal/instruments/muse.html" target="_blank"><b>M</b>USE</a> g<b>A</b>laxy <b>G</b>roups <b>I</b>n <b>C</b>OSMOS (MAGIC) survey (Programs 094.A-0247, 095.A-0118, 096.A-0596, 097.A-0254, 098.A-0017, 099.A-0246, 0100.A-0607, 0101.A-0282, 0102.A-0327, 0103.A-0563, PI T. Contini) is composed of 18 datacubes, observed with exposure times from 1 to 10 hours, with a median of 4.3 hours, using the wide-field mode, with a spectral sampling of 1.25 Angstroms and a spatial sampling of 0.2 arcsecond. The datacubes cover the wavelength range between 4700 and 9350 Angstroms and have an image quality better than 0.7’’ FWHM owing to good observing conditions and/or to the use of adaptive optics. The median 3σ point-source flux limit of an unresolved emission line reaches 3.6x10<sup>-19</sup> erg s<sup>-1</sup> cm<sup>-2</sup> and the median point source magnitude limit is about 28.5 at 5σ in white-light images. The MAGIC survey datacubes target 15 known massive groups and clusters at intermediate redshift (0.3 < z < 0.8), 14 of which being located in the COSMOS field and one in the VVDS field. This dataset is incredibly rich and contains more than one thousand of objects, from stars to high redshift galaxies, as well as extended nebulae. </div> <div class="read_more_link" align="left"> <a href="/cms/eso-archive-news/release-of-muse-galaxy-groups-in-cosmos-magic-survey-datacubes.html">Read more</a> </div> <br> <div class="clear"></div> </div> </div> </div> <div class="pr_box"> <h2 class="pr_headline"> <a href="/cms/eso-archive-news/ERIS-release-of-pipeline-processed-imaging-and-IFU-products.html">ERIS release of pipeline processed imaging and IFU products</a> </h2> <div class="pr_lead"> <div class="pr_list_text"> <strong>Published: 15 Apr 2024</strong> <div class="teasertext"> <h2><b>Release of pipeline processed imaging and IFU products from ERIS </b></h2> <p>The two newly available data collections, <b>ERIS-NIX</b> and <b>ERIS-SPIFFIER,</b> provide access to reduced scientific imaging products and 3D data cubes, respectively.
