Abstract
Using multi-wavelength data (HI, UV and optical data) we have found dozens of star-forming regions in the HI bridge between M81 and M82 and in the outskirts of the compact group, HCG00. From their physical properties we have established that these are young star-forming regions which are formed in the low HI column densities of the tidal debris. We were also able to establish that in M81/M82 an old population is also present which was ejected into the intergalactic medium during a tidal passage.
