Super Star Clusters in Sbs0335-052e
As one of the lowest metallicity star-forming galaxies, with a nucleus of several super star clusters (SSCs), SBS0335-052E is the subject of substantial current study. We present new insights on this galaxy based on new and archival high spatial resolution NICMOS and attitude control system images. We provide new measurements and limits on the size of several of the SSCs. The images have suffic...
متن کامل1 Evolved Super Star Clusters in M82
We present high-resolution optical and near-infrared HST observations of two adjacent regions in the fossil star-burst region in M82, B1 and B2. Age estimates date the cluster population in the fossil star-burst between ∼ 2 × 10 8 and ∼ 10 × 10 9 years, assuming solar metallicity. The star cluster population in B2 is more heavily affected by internal extinction than that in B1. Although our clu...
متن کاملWatching 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 ...
متن کاملThe Birth of Super Star Clusters
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....
متن کاملStar clusters and galactic chemodynamics: Implosive formation of super star clusters
We numerically investigate dynamical and chemical properties of star clusters (open and globular clusters, and “super star clusters”, SSC) formed in interacting/merging galaxies. The investigation is two-fold: (1) large-scale (100pc-100kpc) SPH simulations on density and temperature evolution of gas in interacting/merging galaxies and (2) small-scale ones on the effects of high gas pressure of ...
