In the Coma cluster, the core radius measured from the galaxy density is rc=200 kpc from Table 7.1. Make a crude model by assuming the cluster to be a Plummer sphere; from Problem 3.2, show that aP ≈300 kpc. Taking the average velocity dispersion σr from Table 7.1, use the result of Problem 3.11 and follow the method of Problem 3.13 to show that ℳ ∼7 ×10^14 ℳ⊙, implying ℳ / L ∼150 ℳ⊙ / L⊙ | Numerade

The Coma Cluster is at a distance of 100 Mpc from Earth. The galaxy NGC123 is probably moving away at speed 1320 (km)/(s). How far is it from us at the moment? Recessing galaxies at very high speeds have been found to be farther away from us (appear dimmer than expected) than they should be according to Hubble's law. Has the Hubble constant in the past had to be greater or smaller than it is today to explain the findings?Provide the final answer in kilometers to two significant figures.

SOLVED:Estimate how long a galaxy in the Coma cluster would take to travel from one side of the cluster to the other. Assume that the galaxy moves with a constant speed equal to the cluster's radial velocity dispersion. How does this compare with the Hubble time, tH ? What can you conclude about whether the galaxies in the Coma cluster are gravitationally bound?
