cds-question@unistra.frgalaxiesphotometryvisible-astronomyspectroscopyWe search for the galaxies associated with the intervening MgII absorbers over a redshift range of 0.4<=z<=1 using imaging data from DESI Legacy Imaging Surveys and measure the redshift based on direct detection of nebular emission in the background quasar spectra from SDSS survey. We find 270 MgII absorbers associated with strong [OII] or, [OIII] and H{beta}nebular emissions, at 2.5{sigma} level. Among them, for 213 MgII absorbers, we detect an absorber host galaxy at impact parameters of 4<={rho}<=16kpc, including three absorbers associated with a galaxy pair, with best-fit galaxy SED model based on multi-passband photometric data from DESI Legacy Imaging surveys, supplemented with the infrared VISTA and unWISE imaging surveys. The detection rate of MgII absorber host with strong [OII] nebular emission in the finite SDSS fiber of 2-3 arcsec diameter increases from 0.2% to ~3% with increasing equivalent width from 0.3{AA} to ~3.5{AA}, which remains near-constant across the probed redshift range. The associated MgII host galaxies exhibit a wide range of stellar mass from 7.94<=log(M*/M_{sun}_)<=11.11, with an average star-formation rate (SFR) of 5.81M_{sun}_/yr. The MgII absorber hosts selected based on [O II] nebular emission mostly exhibit active star-forming systems including 13.4% starburst systems, but 10.2% with suppressed SFR. The near-constant absorption strength at low-impact parameters suggests a high gas covering fraction. We find that the MgII equivalent width (W2796) positively correlates with SFR and specific-SFR, likely indicating their wind origin. The average velocity offset between the host and absorber suggests that the MgII gas is bound within the dark matter halo.2025A&A...695A.207Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/695/A207CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/695/A206 : BEINGMgII.
