Best-fit SED of host galaxies associated with USMgII absorbers. The postage stamp HSC color composite images, centered on the quasar, are depicted with gray contours. The SDSS fiber, with a radius of 1.5″, is indicated by a dashed yellow circle, while the cyan-colored aperture highlights the USMgII host galaxy. The second column exhibits the corresponding multiband best-fit SED model at the absorber redshift.
