摘要：
We are studying a sample of spiral galaxies which present a nuclear starburst. The final aim is to establish the conditions needed to enter into the supergalactic wind phase. We are analyzing Fabry-Perot observations (TAURUS(1)) taken at Roque de los Muchachos Observatory (ORM), Spain. We used MATADOR(2) for analyzing the TAURUS datacubes. We have a sample of 12 galaxies. The data are to be complemented with optical, infrared (ISO) and X-rays observations. In this contribution, we present preliminary work on the galaxy NGC 4631. Recently, X-rays observations from CHANDRA have put into evidence the escape of hot gas from the disc into the halo. We identify supergalactic winds (SGW) features in the inner gas in the SE direction.
