A potential galaxy candidate from the faint end population at z_abs = 1.018, along J234451.70+000603.2 quasar sight line at z_qso = 2.4. Left panel: The postage stamp HSC multiband images after quasar removal. Top right panel: HSC five band median co-added image showing a potential host galaxy detected at 2.7σ level, marked as cyan aperture. The SDSS fiber, with a radius of 1.5″, is indicated by a dashed circle whereas the quasar is shown as contours. Bottom right panel: An emission signature at the expected [O II] λλ3727, 3729 wavelength, detected at ∼3.2σ level.
