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…
Gemini Spectroscopy and HST Imaging of the Stellar Cluster Population in Region B of M82
I. S. Konstantopoulos, N. Bastian, L. J. Smith +3
We present new spectroscopic observations of the stellar cluster population of region B in the prototype starburst galaxy M82 obtained with the Gillett Gemini-North 8.1-metre teles…
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…
