A detailed study of the enigmatic cluster M82F
N. Bastian, I. Konstantopoulos, L. J. Smith +3
We present a detailed study of the stellar cluster M82F, using multi-band high resolution HST imaging and deep ground based optical slit and integral field spectroscopy. Using the…
The effects of spatially distributed ionisation sources on the temperature structure of HII region
B. Ercolano, N. Bastian, G. Stasinska
Spatially resolved studies of star forming regions show that the assumption of spherical geometry is not realistic in most cases, with a major complication posed by the gas being i…
Gemini Spectroscopic Survey of Young Star Clusters in Merging/Interacting Galaxies. II. NGC 3256 Clusters
Gelys Trancho, Nate Bastian, Bryan W. Miller +1
We present Gemini optical spectroscopy of 23 young star clusters in NGC3256. We find that the cluster ages range are from few Myr to ~150 Myr. All these clusters are relatively mas…
Cluster Disruption: Combining Theory and Observations
Nate Bastian, Mark Gieles
We review the theory and observations of star cluster disruption. The three main phases and corresponding typical timescales of cluster disruption are: I) Infant Mortality (~10^7 y…
Variation of the cluster luminosity function across the disk of M51
M. R. Haas, M. Gieles, R. A. Scheepmaker +3
We study the luminosity function (LF) of the star clusters in M51. Comparing the observed LF with the LF resulting from artificial cluster populations suggests that there exists an…
