2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/13350We have carried out radio studies of the surroundings of the superluminal microquasar GRS~1915+105. Our main goal was to understand the possible relation of GRS~1915+105 with two infrared/radio sources that appear symmetrically located with respect to GRS~1915+105 and aligned with the position angle of the relativistic ejecta. We have also studied a nearby supernova remnant to test if the event that created the remnant could have been the progenitor of this hard X-ray binary.4 pages, 4 figuresAstrophysicstext
