چکیده

Super star clusters (SSCs) are the most extreme star forming environments in the local universe. Packed with massive stars, these clusters have a major impact on the energetics and morphology of galaxies. Massive stars ionize the interstellar medium and power the infrared radiation of dust, and their stellar winds and supernovae release mechanical energy that can trigger further star formation. In addition, the most massive and dense SSCs are the likely progenitors of ancient globular clusters. For all of these reasons, there is wide-spread interest in the birth and evolution of SSCs. The goal of my research is to improve the current understanding of SSC formation and early evolution by combining observations of starburst galaxies spanning the radio to ultraviolet wavelength regimes. This work capitalizes on the unique capabilities of the Hubble and Spitzer Space Telescopes and the Very Large Array to probe the gaseous and dusty sites of star formation at high resolution.

Probing the Birth of Super Star Clusters: Implications for Massive Star Formation

Super Star Clusters are one of the most extreme star forming environments in the universe, and the most massive and dense of these may be proto globular clusters. Like individual massive stars, the earliest stages of super star cluster evolution are deeply obscured, and therefore our knowledge about their birth environments is currently very incomplete. However, the study of natal super star cl...

Watching the Birth of Super Star Clusters

Subarcsecond infrared and radio observations yield important information about the formation of super star clusters from their surrounding gas. We discuss the general properties of ionized and molecular gas near young, forming SSCs, as illustrated by the prototypical young, forming super star cluster nebula in the dwarf galaxy NGC 5253. This super star cluster appears to have a gravitationally ...

The Properties of Super Star Clusters in A Sample of Starburst Galaxies

Super star clusters” are the most massive extreme in the continuum of young star clusters. In this thesis, I examine the properties of such super star clusters in a sample of starburst galaxies with space and ground-based observations and in the optical, mid-infrared, and radio regimes. Using optical photometry, I estimate the ages and masses, as well as construct luminosity functions for the s...

Scaling relations in dynamical evolution of star clusters

We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...

Young Star Clusters in Starburst Environments 1

Recent high-resolution observations with the Hubble Space Telescope (HST) reveal that young star clusters of extraordinary luminosity and compactness (“super star clusters”) are commonly found in starburst systems. Cluster formation appears to be a dominant mode of star formation in starbursts. The principal properties of the young clusters are summarized. A new ultraviolet HST imaging survey o...
