The vela cloud: A giant H i anomaly in the NGC 3256 group
We present Australia Telescope Compact Array (ATCA) observations of a galaxy-sized intergalactic H I cloud ("the Vela Cloud") in the NGC3256 galaxy group. The group contains the prominent merging galaxy NGC3256, which is surrounded by a number of H I fragments, the tidally disturbed galaxy NGC3263, and several other peculiar galaxies. The Vela Cloud, with an H I mass of 3-5 , resides southeast of NGC3256 and west of NGC3263, within an area of 9′ × 16′ (100 kpc × 175 kpc for an adopted distance...[Show more]
