A river of stars in the M83 halo VIMOS VLT MartínezDelgado PI. Subarcsecond imaging provided by 8 meterclass telescope allows to resolve stellar streams and extended disks in spiral galaxies within 5 Mpc (HSTACS 11 Mpc)
MartínezDelgado et al. 2007 Sacket (1995) reported a metalrich halo, but fields are contaminated by tidal debris. Complex structure explained by one merger 4.5 Gyr ago: an unprecedent view of a multiwarp old tidal stream Progenitor survived! Possible hidden behind the disk.
