Spectroscopic Constraints on the Form of the Stellar Cluster Mass Function
N. Bastian, I. S. Konstantopoulos, G. Trancho +5
This contribution addresses the question of whether the initial cluster mass function (ICMF) has a fundamental limit (or truncation) at high masses. The shape of the ICMF at high m…
Gemini Spectroscopic Survey of Young Star Clusters in Merging/Interacting Galaxies. IV. Stephan's Quintet
G. Trancho, I. Konstantopoulos, N. Bastian +4
We present a spectroscopic survey of 21 young massive clusters and complexes and one tidal dwarf galaxy candidate (TDG) in Stephan's Quintet, an interacting compact group of galaxi…
Evidence for Environmentally Dependent Cluster Disruption in M83
N. Bastian, A. Adamo, M. Gieles +8
Using multi-wavelength imaging from the Wide Field Camera 3 on the Hubble Space Telescope we study the stellar cluster populations of two adjacent fields in the nearby face-on spir…
Star Clusters as Tracers of Interactions in Stephan's Quintet (Hickson Compact Group 92)
K. Fedotov, S. C. Gallagher, I. S. Konstantopoulos +5
Stephan's Quintet (SQ) is a compact group of galaxies that exhibits numerous signs of interactions between its members. Using high resolution images of SQ in B438, V606, and I814 b…
Star Clusters in the Tidal Tails of Interacting Galaxies: Cluster Populations Across a Variety of Tail Environments
B. Mullan, I. S. Konstantopoulos, A. A. Kepley +17
We have searched for compact stellar structures within 17 tidal tails in 13 different interacting galaxies using F606W- and F814W- band images from the Wide Field Planetary Camera…
The Optical Structure of the Starburst Galaxy M82. II. Nebular Properties of the Disk and Inner-Wind
M. S. Westmoquette, J. S. Gallagher, L. J. Smith +3
(Abridged) In this second paper of the series, we present the results from optical Gemini-North GMOS-IFU and WIYN DensePak IFU spectroscopic observations of the starburst and inner…
Gemini Spectroscopic Survey of Young Star Clusters in Merging/Interacting Galaxies. III. The Antennae
Nate Bastian, Gelys Trancho, Iraklis S. Konstantopoulos +1
We present optical spectroscopy of 16 star clusters in the merging galaxies NGC 4038/39 ("The Antennae") and supplement this dataset with HST imaging. The age and metallicity of ea…
