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

He i in the central giant H ii region of NGC 5253 - A 2D observational approach to collisional and radiative transfer effects
Context. NGC 5253 is a nearby peculiar blue compact dwarf (BCD) galaxy that, on account of its proximity, provides an ideal laboratory for detailed spatial study of starburst galaxies. An open issueExpand
Highly efficient star formation in NGC 5253 possibly from stream-fed accretion
TLDR
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
