A Direct DESI–SDSS Two-Fibre Test of Aperture Bias in Optical Emission-Line Diagnostics
Fixed angular apertures sample different physical regions of nearby galaxies and can therefore bias optical emission-line diagnostics. We use 20,545 high-confidence emission-line galaxies observed by both the Dark Energy Spectroscopic Instrument (DESI) and the Sloan Digital Sky S...
