Padua Research Archive, l’archivio istituzionale della produzione scientifica dell’Università degli Studi di Padova, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ateneo. Padua Research Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishWe measured the velocity curve and the velocity dispersion profile of the ionized gas along the major axis of the edge-on galaxy UGC 10205. The observed kinematics extends up to about 40 arcsec from the nucleus. In the inner +/-13 arcsec of this early-type spiral three kinematically distinct gaseous components are present. We disentangle a fast-rotating and a slow-rotating component. They give to the UGC 10205 velocity curve a "figure-of-eight" appearance. A third velocity component is also detected on the southeast side of the galaxy. Possibly it is produced by gas in non-circular motions.
