Do the Shapes of Elliptical Galaxies Really Reflect Their True

Question 23

Multiple Choice

Do the shapes of elliptical galaxies really reflect their true shape?


A) No. The shapes of most of them have been severely distorted by gravitational lensing around the supermassive black hole at their centers.
B) No. They may all be the same shape but viewed either edge on, face on, or in between these two cases.
C) No, because we cannot see the outlying spherical shells of material detected by radio telescopes around elliptical galaxies.
D) Yes. The shapes we see have been shown to be their true three-dimensional shape.
