cds-question@unistra.frmolecular-cloudsinterstellar-mediuminfrared-sourcesAdaptive optics images are used to test the hypothesis that the explosive BN/KL outflow from the Orion OMC1 cloud core was powered by the dynamical decay of a non-hierarchical system of massive stars. Narrow-band H_2_, [FeII], and broad-band Ks obtained with the Gemini South multi-conjugate adaptive optics (AO) system GeMS and near-infrared imager GSAOI are presented. The images reach resolutions of 0.08 to 0.10" to the 0.07" diffraction limit of the 8-meter telescope at 2.12um. Comparison with previous AO-assisted observations of sub-fields and other ground-based observations enable measurements of proper motions and the investigation of morphological changes in H_2_ and [FeII] features with unprecedented precision. The images are compared with numerical simulations of compact, high-density clumps moving ~10^3^ times their own diameter through a lower density medium at Mach 10^3^.2015A&A...579A.130Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/579/A130CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/120/1426 : Chandra sources in ONC + BN-KL (Garmire+, 2000)J/ApJS/156/127 : 350{mu}m molecular line survey of Orion KL (Comito+, 2005)J/A+A/532/A32 : HCOOCH3 map of Orion-KL (Favre+, 2011)J/A+A/559/A51 : HC_3_N in Orion KL (Esplugues+, 2013)J/ApJ/769/48 : Water maser in Orion-KL with Herschel (Neufeld+, 2013)J/A+A/572/A44 : Vibrationally excited vinyl cyanide in Orion-KL (Lopez+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/579/A130https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/579/A130http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/579/A130https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/579/A130https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/579/A130http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/579/A130GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/579/A130/list (List of FITS images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/579/A130/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/579/A130/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/579/A130/list?GETtext/xml+votable180.050000true83.81257-5.362820.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/579/A1306/21439https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/579/A130?format=asciiInfrareddefaultJ/A+A/579/A130/listList of FITS imagesrecnoRecord number assigned by the VizieR team.
