A search for nitrogen-enriched quasars in the Sloan Digital Sky Survey early data release.

Abstract (from CDS):

A search for nitrogen-rich quasars in the Sloan Digital Sky Survey Early Data Release (SDSS EDR) catalog has yielded 16 candidates, including five with very prominent emission, but no cases with nitrogen emission as strong as in Q0353-383. The quasar Q0353-383 has long been known to have extremely strong nitrogen intercombination lines at 1486 and 1750 Å, implying an anomalously high nitrogen abundance of ∼15 times solar. It is still the only one of its kind known. A preliminary search through the EDR using the observed property of the weak C IV emission seen in Q0353-383 resulted in a sample of 23 objects with unusual emission- or absorption-line properties, including one very luminous (z~2.5) star-forming galaxy. We present descriptions, preliminary emission-line measurements, and spectra for all the objects discussed here.
