We show that the globular cluster mass function (GCMF) in the Milky Way depends on cluster half-mass density,ρh, in the sense that the turnover mass MTO increases withρh while the width of the GCMF decreases. We argue that this is the expected signature of the slow erosi on of a mass function that initially rose towards low masses, predominantly through cluster evaporation driven by i ternal two-body relaxation. We find excellent agreement between the observed GCMF—including its depende nce on… CONTINUE READING
