In science:

This factor is, in principle, a random quantity that differs from one cluster to another; however, this number is expected to be roughly the same for all clusters that contribute to the spectral sum at low frequencies due to averaging, since such clusters are all large, and in some sense similar.
Dynamics and transport in random quantum systems governed by strong-randomness fixed points
There are essentially two factors which determine how much gas is present in a globular cluster at the current epoch: (i) the mass and central escape speed of the cluster, and (ii) the orbit of the cluster and its current position and velocity.
Bondi-Hoyle-Lyttleton Accretion Model for Low-luminosity X-ray Sources in Globular Clusters
For the more distant clusters some of the typical tools are the specific globular cluster frequency, the cluster luminosity function, and color-color diagrams.
The Formation of Star Clusters
Ground based observations, such as those of Lutz (1991), were inconclusive, since they were not able to resolve the clusters to determine whether they were associations or HII regions, with Reff ≈ 100 pc, or compact clusters similar to the globular clusters in the Milky Way, with Reff ≈ 3 pc (van den Bergh, 1996).
The Formation of Star Clusters
Looking at resolved clusters, Kennicutt and Chu (1988) concluded “that populous clusters may be forming in giant HII regions, but only a small fraction of giant HII regions are likely to contains such clusters”.
The Formation of Star Clusters
What fraction of stars are formed in clusters? Since only a subsample of the young clusters are likely to survive, an obvious question is whether most of the field stars in a galaxy are originally formed in clusters.
The Formation of Star Clusters
