NICI: combining coronagraphy, ADI, and SDI
Etienne Artigau, Beth A. Biller, Zahed Wahhaj +9
The Near-Infrared Coronagraphic Imager (NICI) is a high-contrast AO imager at the Gemini South telescope. The camera includes a coronagraphic mask and dual channel imaging for Spec…
The Early Expansion of Cluster Cores
N. Bastian, M. Gieles, S. P. Goodwin +4
The observed properties of young star clusters, such as the core radius and luminosity profile, change rapidly during the early evolution of the clusters. Here we present observati…
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…
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…
Gemini Spectroscopic Survey of Young Star Clusters in Merging/Interacting Galaxies. I. NGC 3256 Tidal-Tail Clusters
Gelys Trancho, Nate Bastian, Francois Schweizer +1
We present Gemini optical spectroscopy of three young star clusters in the western tidal tail of NGC3256. Compact star clusters (as opposed to dwarf-galaxy candidates) in tidal tai…
The Star Cluster Population in the Tidal Tails of NGC 6872
N. Bastian, M. Hempel, M. Kissler-Patig +2
We present a photometric analysis of the rich star cluster population in the tidal tails of NGC 6872. We find star clusters with ages between 1 - 100 Myr distributed in the tidal t…
