Evidence for two distinct stellar initial mass functions: probing for clues to the dichotomy
TL;DR: In this article, the velocity dispersions of 11 Local Group globular clusters using spatially integrated spectra were used to expand the sample of clusters with precise integrated-light velocities to 29, over 4 different host galaxies.

A Database of 2MASS Near-Infrared Colors of Magellanic Cloud Star Clusters
TL;DR: In this paper, the authors present a new database of integrated near-infrared JHKs magnitudes for 75 star clusters in the Magellanic Clouds, using the 2-Micron All-Sky Survey (2MASS).

Evidence for two distinct stellar initial mass functions: revisiting the effects of cluster dynamical evolution
TL;DR: In this paper, the authors measured the velocity dispersions of six galactic globular clusters using spatially integrated spectra, to test for the effects of internal dynamical evolution in the stellar mass-to-light ratios, *, of star clusters.

TL;DR: In this article, the luminous Class I protostar HBC 494, embedded in the Orion A cloud, is associated with a pair of reflection nebulae, Re50 and Re50N, which appeared sometime between 1955 and 1979.
