A low-mass HI companion of NGC 1569? | J. M. Stil

19 Jun 1998 | Subject: | astro-ph | Abstract: | High-sensitivity maps of the large-scale structure of atomic hydrogen in the starburst dwarf galaxy NGC 1569 show evidence for an HI cloud with a mass of 7*10**6 M_sun, at a projected distance of 5 kpc from the parent galaxy. This cloud may be a condensation in a low-column-density HI halo or a companion galaxy/HI-cloud. NGC 1569 and its companion are connected by a low surface brightness HI bridge. At the edge of NGC1569, the HI bridge coincides with H_alpha arcs, also detected in soft X-rays. | Source: | arXiv, astro-ph/9806267 | Services: | Forum | Review | PDF | Favorites |
