We examine the diagnostic power of rest-frame ultraviolet (UV) nebular emission lines, and
compare them to more commonly used rest-frame optical emission lines, using the test case
of a single star-forming knot of the bright lensed galaxy RCSGA 032727–132609 at redshift
z ∼ 1.7. This galaxy has complete coverage of all the major rest-frame UV and optical emission
lines from Magellan/MagE and Keck/NIRSPEC. Using the full suite of diagnostic lines, we
infer the physical properties: nebular...[Show more]
