  • Detailed neutral hydrogen observations have been obtained of the large barred spiral galaxy NGC 3992 and its three small companion galaxies, UGC 6923, UGC 6940, and UGC 6969. For the main galaxy, the Hi distribution is regular with a low level radial extension outside the stellar disc. However, at exactly the region of the bar, there is a pronounced central Hi hole in the gas distribution. Likely gas has been transported inwards by the bar and because of the emptyness of the hole no large… CONTINUE READING
