Stellar Streams Reveal the Mass Loss of Globular Clusters
Published 2025-01-01“…Globular cluster (GC) streams, debris of stars tidally stripped from their progenitor GCs, have densities that correlate positively with the GC mass-loss rate. …”

GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
Published 2025-01-01“…The progenitor of the GD-1 stream was an accreted globular cluster (GC) and: (a) the cocoon was produced by pre-accretion tidal stripping of the GC while it was still inside its parent dwarf galaxy; (b) the cocoon comprises debris from the parent dwarf galaxy; (c) an initially thin GC tidal stream was heated by impacts from dark subhalos in the Milky Way; (d) an initially thin GC stream was heated by a massive Sagittarius dwarf galaxy; or a combination of some of these. …”

Rates of Stellar Tidal Disruption Events around Intermediate-mass Black Holes
Published 2025-01-01“…The IMBH TDEs from galactic nuclei have an overall volumetric rate comparable to SMBH TDEs at ∼10 ^−7 Mpc ^−3 yr ^−1 , and off-center IMBH TDEs from globular clusters have a volumetric rate that is one or two orders of magnitude lower, assuming that their occupation fraction varies within 10%–100%. …”
