SDSS-DR3 OVI QSOs absorbers
Listed in IVOA Registry (Virtual Observatory)
We report the results of a systematic search for signatures of metal lines in quasar spectra of the Sloan Digital Sky Survey (SDSS) data release 3 (DR3), focusing on finding intervening absorbers via detection of their OVI doublet.
Description
Here, we present the search algorithm and criteria for distinguishing candidates from spurious Ly{alpha} forest lines. In addition, we compare our findings with simulations of the Ly{alpha} forest in order to estimate the detectability of OVI doublets over various redshift intervals.
We have obtained a sample of 1756 OVI doublet candidates with rest-frame equivalent width (EW)>=0.05{AA} in 855 active galactic nuclei spectra (out of 3702 objects with redshifts in the accessible range for OVI detection).
