Are elliptical galaxies real or just circular galaxies viewed at an oblique angle?
(Apart that is from colliding pairs of galaxies.)
I wonder because I understand that anomalously rapid rotational speed of galaxies is considered a supporting argument for dark matter.
But if galaxies are commonly elliptical then as it would not be possible to tell which axis is pointing towards us (when we lie in its rotational plane), if it is the long one, higher velocities would be seen.
Or perhaps I have misunderstood the term 'elliptical' as applied to galaxies.
Thanks for any comments in reply.
