The nucleation fraction of local volume galaxies

ABSTRACT Nuclear star clusters (NSCs) are a common phenomenon in galaxy centres and found vast majority of galaxies intermediate stellar mass $\approx 10^9\, \mathrm{M}_{\odot }$. Recent investigations suggest that they rarely the least most massive nucleation fraction increases dense environments. It is unclear whether this trend holds true for field due to limited data currently available. Here we present our results on 601 Local Volume ($\lesssim {12}{\, \mathrm{Mpc}}$). Covering more than eight orders magnitude mass, largest sample analysed low-density environment. Within find strong dependence agreement with previous work. We also $M_{\star } \lt 10^{9}\, }$, early-type have higher late-types. The correlates independently Hubble type, local environmental density. compare those cluster environments (Coma, Fornax, Virgo) by compiling calculating masses homogeneous way. significantly lower fractions (up 40 per cent) \lesssim 10^{9.5}\, Our reinforce connection between globular NSCs, but it remains if can explain observed trends type speculate correlation environment weakens densest like Coma Virgo.
