What is the galaxy content of rich, regular clusters like the Coma cluster?
A) more or less even distribution of spirals, ellipticals, irregulars, and S0 galaxies
B) mostly ellipticals and S0 galaxies and relatively few spirals and irregulars
C) entirely elliptical galaxies
D) mostly spirals and irregulars with relatively few ellipticals and S0 galaxies

Question

Quizplus · Accepted Answer

Rich, regular clusters like the Coma cluster are characterized by a predominance of elliptical and S0 (lenticular) galaxies, with relatively few spiral and irregular galaxies. This is due to the dense environment of such clusters, which is conducive to the transformation of spiral galaxies into ellipticals and S0s through processes like galaxy mergers and interactions.
