We report the spectroscopic confirmation of a compact \lya emitting galaxy at $z=5.721$. A FORS2 spectrum of the source shows a strong asymmetric line with a flux of 5$\times10^{-17}$ erg s$^{-1}$ cm$^{-2}$, making it one of the brightest…
We present Herschel observations of six fine-structure lines in 25 Ultraluminous Infrared Galaxies at z<0.27. The lines, [O III]52, [N III]57, [O I]63, [N II]122, [O I]145, and [C II]158, are mostly single gaussians with widths <600 km s-1…
