The nearby dwarf starburst galaxy NGC 5253 hosts a deeply embedded radio-infrared supernebula excited by thousands of O stars. We have observed this source in the 10.5 {mu}m line of S{sup +3} at 3.8 km s{sup -1} spectral and 1.''4 spatial resolution, using the high-resolution spectrometer TEXES on the IRTF. The line profile cannot be fit well by a single Gaussian. The best simple fit describes the gas with two Gaussians, one near the galactic velocity with FWHM 33.6 km s{sup -1} and another of… Expand

Highly efficient star formation in NGC 5253 possibly from stream-fed accretion
It is suggested that high efficiency results from the force-feeding of star formation by a streamer of gas falling into the galaxy, tenfold that of clouds in the Milky Way. Expand
The Youngest Globular Clusters
It is likely that all stars are born in clusters, but most clusters are not bound and disperse. None of the many protoclusters in our Galaxy are likely to develop into long-lived bound clusters. TheExpand
