Detection of spiral magnetic fields in two flocculent galaxies

Two flocculent galaxies NGC 3521 and NGC 5055 has been observed at 10.55GHz with the Effelsberg 100m telescope. In both cases polarized emission reveals substantial radial component of regular magnetic field - similar to that in grand-designed spirals. Comparison with H_alpha distribution obtained at Lowell Observatory is presented. Polarization models discussed, support modern non-standard dynamo concepts for magnetic field generation in galaxies.

Magnetic fields and strong density waves in the interacting galaxy NGC 3627

We present 10.55 GHz observations of strong density-wave spiral NGC 3627. Total power and polarization maps with a resolution of 1.13', sensitive to a weak extended emmision were obtained. In the analysiz we used also available data in the CO ans H_alpha lines. We present simple modelling results showing the imprtance of large-scale dynamo-type magnetic field present despite the strong density-wave action in this galaxy.
