Interactive 3-D map traces galaxy movement in Local Supercluster

New Map Shows the Motion of all the Galaxies in Our Supercluster

SOLVED: Like the Coma cluster, the Virgo cluster contains a large amount of hot (70 million K) intracluster gas that emits X-rays. (a) If the X-ray luminosity of the Virgo cluster's intracluster gas is about 1.5 ×10^36 W, use Eq. ( 20) to find the electron number density and the mass of the gas. Assume that the Virgo cluster is a sphere of radius 1.5 Mpc that is filled with completely ionized hydrogen. Lx=(4)/(3) πR^3 ℒvol (b) Use LV=1.2 ×10^12 L⊙ for the visual luminosity of the Virgo cluster
