| Abstract : | High density, old age, and large stellar numbers make Globular clusters (GCs) efficient factories for a plethora of stellar exotica including compact object binaries, millisecond pulsars, SN1a, and blue stragglers. Host to some of the oldest stars, GCs provide constraints to the star formation history and even the host galaxy's assembly. However, what could have been GC progenitors still remains uncertain. In our study, we explore the possibility that the progenitors of the Milky Way (MW) GCs may have had properties, except for metallicity, very similar to those of the massive young star clusters (YSCs) observed today in starburst galaxies. Our numerical simulations show that star clusters with an initial distribution of masses and sizes similar to the YSCs after 10-12 Gyr of evolution do reproduce the distribution of properties similar to the observed GCs in the MW. In addition to the distribution of the bulk properties of star clusters, this finding also have implications on the production rate of various stellar exotica including the merger rate of binary black holes detectable by the LIGO-Virgo-Kagra detectors. |
