... Thanks to its gravitationally lensed nature, the z = 2.7276 galaxy MS 1512−cB58 (or cB58 for short) provides an unusually clear window on the population of starforming galaxies identified at these redshifts through the Lyman break technique (Steidel et al., 1996). Discovered by Yee et al. (1996), cB ...
