As part of a continuing survey of nearby galaxies, we have mapped the neutral gas content of the low surface brightness Magellanic-type galaxy NGC 3109 and its environment, including the Antlia dwarf galaxy, at unprecedented velocity resolution and brightness sensitivity. The H I mass of NGC 3109 is measured to be 3.8 ± 0.5 × 108 M⊙. A substantial warp in the disk of NGC 3109 is detected in the H I emission image in the form of an extended low surface brightness feature. We report a positive… Expand
