Which primary component of the Virgo Cluster is centered on the giant elliptical galaxy M87?
Answer
Virgo A
Virgo A is identified as the dominant subclump within the Virgo Cluster structure. This component is centered around the exceptionally large elliptical galaxy designated M87, which is also sometimes referred to as Virgo A itself. Virgo A holds a dominant position not only structurally but also gravitationally, possessing an estimated mass that is approximately ten times greater than the mass of the other major subclumps present in the cluster. This mass concentration is central to the cluster's overall gravitational reach.
