Detection of spiral magnetic fields in two flocculent galaxies

J. Knapik, M. Soida, R. -J. Dettmar +2

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 componen…

Box- and peanut-shaped bulges: II. NIR observations

R. Luetticke, R. -J. Dettmar, M. Pohlen

We have observed 60 edge-on galaxies in the NIR in order to study the stellar distribution in galaxies with box/peanut-shaped bulges. The much smaller amount of dust extinction at…
