... The Hercules Cluster of Galaxies or Abell 2151 is a rather distant (by UIT imaging standards), spiral rich cluster with lots of interactinggalaxies. ...
... In this exercise, you will use a computational engine to model two interactinggalaxies to see if you can reproduce the observed morphology of two real systems. ...
... Interactinggalaxies were assigned T = 11. as determined by the SWML method: the reduced ь 2 љ from the likelihood ratio test of Efstathiou et al. (1988) is 14.04, which implies that the probability of exceeding this ь 2 љ by chance is ё 2:5 \Theta 10 ...
... It is interacting with a small companion galaxy. That interaction serves to redistribute and compress the gas which facilitates star formation. ...
... Best argument: baryonic density fluctuations will not produce galaxies you need a heavy particle that is not effected by radiation pressure in order to eventually form galaxies . ...
