Radio continuum emission from M31 and M33
Rainer Beck
The radio emission from M31 (like HI, CO, FIR and Hα) is concentrated in the '10 kpc ring', giving an impressive example that cosmic rays are produced in star-forming regions. M31…
Regular magnetic fields in the dwarf irregular galaxy NGC 4449
K. T. Chyzy, R. Beck, S. Kohle +2
We present a high-resolution VLA study of the total power and polarized radio continuum emission at 8.46 and 4.86 GHz of the irregular galaxy NGC 4449, known for its weak rotation…
New clues to the magnetic field structure of M31
J. L. Han, R. Beck, E. M. Berkhuijsen
We observed 21 polarized background radio sources in the field of M31 at 1.365 GHz and 1.652 GHz, and determined their rotation measures (RMs). The RM data show that the regular ma…
ROSAT PSPC X-ray observations of the nearby spiral galaxy M83
M. Ehle, W. Pietsch, R. Beck +1
The nearly face-on SBc galaxy M83 (NGC 5236) was observed for 25 ksec with the ROSAT PSPC. We detected 13 point-like sources in this galaxy, 10 of which were previously unknown. We…
