On the origin of double main-sequence turn-offs in star clusters of the Magellanic Clouds
K. Bekki, A. D. Mackey
Recent observational studies of intermediate-age star clusters (SCs) in the Large Magellanic Cloud (LMC) have reported that a significant number of these objects show double main-s…
The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation
M. Bellazzini, R. A. Ibata, S. C. Chapman +6
We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N). We…
Multiple stellar populations in three rich Large Magellanic Cloud star clusters
A. D. Mackey, P. Broby Nielsen, A. M. N. Ferguson +1
We present deep colour-magnitude diagrams for three rich intermediate-age star clusters in the Large Magellanic Cloud, constructed from archival ACS F435W and F814W imaging. All th…
Simple Stellar Population Models as probed by the Large Magellanic Cloud Star Cluster ESO 121-SC03
Y. Xin, L. Deng, R. de Grijs +2
The presence of blue straggler stars (BSs) in star clusters has proven a challenge to conventional simple stellar population (SSP) models. Conventional SSP models are based on the…
A double main sequence turn-off in the rich star cluster NGC 1846 in the Large Magellanic Cloud
A. D. Mackey, P. Broby Nielsen
We report on HST/ACS photometry of the rich intermediate-age star cluster NGC 1846 in the Large Magellanic Cloud, which clearly reveals the presence of a double main sequence turn-…
The effect of stellar-mass black holes on the structural evolution of massive star clusters
A. D. Mackey, M. I. Wilkinson, M. B. Davies +1
We present the results of realistic N-body modelling of massive star clusters in the Magellanic Clouds, aimed at investigating a dynamical origin for the radius-age trend observed…
