THE LAST EIGHT-BILLION YEARS OF INTERGALACTIC Si IV EVOLUTION
We identified 24 Si iv absorption systems with z ≾ 1 from a blind survey of 49 low-redshift quasars with archival Hubble Space Telescope ultraviolet spectra. We relied solely on the characteristic wavelength separation of the doublet to automatically detect candidates. After visual inspection, we de...
