Pre-peak ram pressure stripping in the Virgo cluster spiral galaxy NGC 4501
B. Vollmer, M. Soida, A. Chung +5
VIVA HI observations of the Virgo spiral galaxy NGC 4501 are presented. The HI disk is sharply truncated to the southwest, well within the stellar disk. A region of low surface-den…
The characteristic polarized radio continuum distribution of cluster spiral galaxies
B. Vollmer, M. Soida, R. Beck +5
Deep observations of 6cm polarized radio continuum emission of 8 Virgo spiral galaxies are presented. All galaxies show strongly asymmetric distributions of polarized intensity wit…
Magnetic fields and ionized gas in nearby late type galaxies
K. T. Chyzy, D. J. Bomans, M. Krause +3
In order to analyze the importance of the star formation rate in generating and amplifying magnetic fields in the interstellar medium we obtained deep total power and polarization…
Large-scale magnetized outflows from the Virgo Cluster spiral NGC4569
K. T. Chyzy, M. Soida, D. J. Bomans +3
Using the Effelsberg radio telescope at 4.85GHz and 8.35 GHz we discovered large symmetric lobes of polarized radio emission around the strongly HI deficient Virgo cluster spiral g…
Magnetic Fields and Ionized Gas in the Local Group Irregular Galaxies IC10 and NGC6822
K. T. Chyzy, J. Knapik, D. J. Bomans +4
We performed a high-sensitivity search for galaxy-scale magnetic fields by radio polarimetry at 10.45GHz and 4.85GHz with the Effelsberg 100m radio telescope, accompanied by Halpha…
The thermal and non-thermal gaseous halo of NGC5775
R. Tuellmann, R. -J. Dettmar, M. Soida +2
In this letter we present first results from spectroscopic observations of Diffuse Ionized Gas (DIG) in the halo of NGC5775 obtained with FORS1 attached to UT1/Antu of the Very Lar…
