Inference of black-hole mass fraction in Galactic globular clusters. A multi-dimensional approach to break the initial-condition degeneracies

Context. Globular clusters (GCs) are suggested to host many stellar-mass black holes (BHs) at their centers, thus resulting in ideal testbeds for BH formation and retention theorie…
