[40.06] Extended HI Envelopes Around Low Surface Brightness Galaxies

D. Chin, K. O'Neil (Arecibo Observatory)

Using the Arecibo Gregorian telescope, we undertook to look for extended neutral hydrogen gas around four low surface brightness galaxies in the direction of the Pegasus Cluster ([OBC97] P06-4, [OBC97] P04-1, [OBC97] P06-1, & [OBC97] P02-3). Although uncertainties in the beam pattern made final analysis of the data difficult, three of the galaxies observed appear to have HI gas extending 2--5 times farther than the optical (d27) diameter of the galaxies. Additionally, all three cases show the HI distribution to be fairly lopsided with the optical part of the galaxy lying away from the middle of the neutral gas.
