To this end, we decompose and classify the shape of [O ii] profiles with the first two eigenspectra derived from principal component analysis. Our results show that DESI ELGs have diverse line profiles, which can be categorized into three main types: (1) narrow lines with a median width of ∼50 km s−1, (2) broad lines with a median width of ∼80 km s−1, and (3) two redshift systems with a median velocity separation of ∼150 km s−1, i.e., double-peak galaxies. To investigate the connections between the line profiles and galaxy properties, we utilize the information from the COSMOS data set and compare the properties of ELGs, including star formation rate (SFR) and galaxy morphology, with the average properties of reference star-forming galaxies with similar stellar mass, sizes, and redshifts. Our findings show that, on average, DESI ELGs have a higher SFR and more asymmetrical/disturbed morphology than the reference galaxies. Moreover, we uncover a relationship between the line profiles, the excess SFR, and the excess asymmetry parameter, showing that DESI ELGs with broader [O ii] line profiles have more disturbed morphology and higher SFR than the reference star-forming galaxies. Finally, we discuss possible physical mechanisms giving rise to the observed relationship and the implications of our findings on the galaxy clustering measurements, including the halo occupation distribution modeling of DESI ELGs and the observed excess velocity dispersion of the satellite ELGs.T.W.L. was supported by the National Science and Technology Council (MOST 111-2112-M-002-015-MY3, NSTC 113-2112-M-002-028-MY3), the Ministry of Education, Taiwan (MOE Yushan Young Scholar grant NTU-110VV007, NTU-111V1007-2, NTU-112V1007-3, NTU-113V1007-4), National Taiwan University research grant (NTU-CC-111L894806, NTU-CC-112L893606, NTU-CC-113L891806, NTU-111L7318, NTU-112L7302).
