Simulated Palomar 5 stream created by modeling the host cluster as a Plummer sphere disrupting within an axis-symmetric Galactic potential plus the gravitational effect of 164 other Galactic globular clusters. The top panel shows the distribution of star particles that escaped the cluster due to tidal forces. The bottom panel shows the 1D density profile marginalized over longitude. The gray fill shows a reference simulation that uses the same conditions to produce the stream but does not include the other globular clusters. The large central peak in density is composed of particles still bound to Palomar 5. ℓ0, b0 are located Palomar 5’s cluster’s center of mass. Two large gaps are present due to the passage of two globular clusters. Np indicates the number of particles in a bin, while N is the total number of particles, which is 100 000.
