Abstract: |
We present deep HI 21 cm observations of two nearby spiral galaxies, M 51 and M 83. These observations are 2-10 times more sensitive than previous data taken more than a decade ago, enabling us to detect Galaxy-like HVC complexes and streams in these galaxies over a fairly wide field of view. We detect several HVC candidates with masses ranging from 1.3-9.2×106 Msolar and velocities deviating up to 230 km s-1 from the local galaxy rotation. Additional data processing will enable us to characterize the kinematics of this gas more accurately and allow a comparison with the HVC system associated with our own Galaxy. |
