cds-question@unistra.frgalaxy-clustersredshiftedDetection and study of the intracluster light in rich clusters of galaxies has been a problem of long standing challenge and interest. Using the lowest surface brightness images of the Coma cluster of galaxies in the g and r bands, from the Halos and Environment of Nearby Galaxies (HERON) Coma Cluster Project, we obtained the most extensive image of intracluster light (ICL) in a single cluster to date, spreading over 1.5Mpc from the cluster core. The unprecedented wealth of spectroscopic data made publicly available by the Dark Energy Spectroscopic Instrument (DESI) Early Data Release, complemented with a compilation from the NASA/IPAC Extragalactic Database and the literature, enabled the identification of 2157 galaxy members within Coma, from which 42 distinct groups were identified. The synergy between these high-quality data allowed us to: 1) calculate ICL fractions of 19.9+/-0.5% and 19.6+/-0.6% in the g and r bands, respectively, consistent with a dynamically active cluster, 2) unveil Coma's faintest tidal features, and 3) provide a comprehensive picture of the dynamics and interactions within this complex system. Our findings indicate that the ICL connects several of these groups in a filamentous network, from which we infer the ongoing dynamical processes. In particular, we identified a faint stellar bridge linking the core of Coma with the galaxy NGC 4839, providing compelling evidence that this galaxy has already traversed the central region of the cluster.2025A&A...694A.216Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/694/A216CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/650/A76 : HI content in Coma cluster substructure (Healy+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/694/A216https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/694/A216http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/694/A216https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/694/A216https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/694/A216http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/694/A216GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/694/A216/table1 (Catalog of Coma galaxies within a radius of ~3.8Mpc around the cluster center, galaxy coordinates and spectroscopic redshifts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/694/A216/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/694/A216/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/694/A216/table1?GETtext/xml+votable180.050000true195.4826488929.323511110.0055555555555555565/2594-2595 2600 7031 7037 6/10368 10370-10372 10374 10386 10394 10404-10406 10408-10410 10416 28119 28147 28156-28157 28159https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/694/A216?format=asciidefaultJ/A+A/694/A216/table1Catalog of Coma galaxies within a radius of ~3.8Mpc around the cluster center, galaxy coordinates and spectroscopic redshiftsrecnoRecord number assigned by the VizieR team.
