摘要：
Recent observations with the Australia Telescope Compact Array show that the elliptical galaxy NGC 5266 has a disk of neutral hydrogen extending to almost 10R(e). This HI disk lies along the galaxy's major axis, at right angles to the inner minor-axis dust lane. The geometry and kinematics of the gas will allow us to determine both the intrinsic shape of the stellar galaxy and the mass distribution. The mass-to-light ratio M/L(B) rises from about 2 in the central regions to similar to 12 at 9R(e) (H-0 = 50 km s(-1) Mpc(-1)).
