The visibilities were weighted naturally and with robust=0 with the task tclean of CASA to get different spatial resolutions (160 and 64 AU, respectively). We identified 22 sources with the tool PyBDSF and we estimated their masses and sizes. We found that most of the sources correspond to low-mass protostellar disks but there is a large mass reservoir in the envelope that can feed the protostar to become high-mass stars5 p.application/pdfengcc-by-nc-nd (c) Torres, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Núvol fosc infraroigCúmuls de galàxiesTreballs de fi de grauInfrared dark cloudClusters of galaxiesBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
