cds-question@unistra.frmagellanic-cloudsstar-forming-regionspre-main-sequence-starsinfrared-photometryYoung massive clusters and super star clusters (SSCs) represent an extreme mode of star formation. Far-infrared imaging of the Magellanic Clouds has identified one potential embedded SSC, HSO-BMHERICC-J72.971176-69.391112 (H72.97-69.39 in short), in the southwest outskirts of the Large Magellanic Cloud. We present Gemini Flamingos 2 and GSAOI near-infrared imaging of a 3'x3' region around H72.97-69.39 in order to characterize the stellar content of the cluster. The stellar content is probed down to 1.5M{sun}. We find substantial dust extinction across the cluster region, extending up to A_K_ of 3. Deeply embedded stars are associated with ALMA-detected molecular gas suggesting that star formation is ongoing. The high spatial resolution of the GSAOI data allows identification of the central massive object associated with the ^13^CO ALMA observations and detection of fainter low-mass stars around the H30{alpha} ALMA source. The morphology of the molecular gas and the nebulosity from adjacent star formation suggest they have interacted covering a region of several parsecs. The total stellar content in the cluster is estimated from the intermediate and high-mass stellar content to be at least 10000M{sun}, less than R136 with up to 100000M{sun} within 4.7pc radius, but places it in the regime of an SSC. Based on the extinction determination of individual stars we estimate a molecular gas mass in the vicinity of H72.97-69.39 of 6600M{sun}, suggesting more star formation can be expected.2021AJ....161..206Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/206CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/707/1347 : HST F160W photometry in RMC 136 (Andersen+, 2009)J/ApJS/184/172 : High and intermediate-mass YSOs in the LMC (Gruendl+, 2009)J/AJ/146/62 : HERschel HERITAGE in Magellanic Clouds (Meixner+, 2013)J/AJ/148/124 : Herschel key program Heritage (Seale+, 2014)J/A+A/578/A4 : Photometry and motions in Arches & Quintuplet (Stolte+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/161/206https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/161/206http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/161/206https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/161/206https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/161/206http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/161/206GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/161/206/table1 (Sources identified within the GSAOI field with photometric errors below 0.1mag)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/161/206/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/161/206/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/161/206/table1?GETtext/xml+votable180.050000true72.98383611-69.389466940.0055555555555555566/330787.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/161/206?format=asciiInfrareddefaultJ/AJ/161/206/table1Sources identified within the GSAOI field with photometric errors below 0.1magrecnoRecord number assigned by the VizieR team.
