英文摘要We have obtained deep J and Ks-band images centered on a bright radio quiet QSO UM 402 (z_(em) = 2.856) using the IRCS camera and adaptive optics systems that are part of the Subaru Telescope, as well as retrieved WFC3/F140W archive images of this object. A faint galaxy (m_k = 23.32±0.05 in the Vega magnitude system) that lies ~2.4" north of the QSO sightline has been clearly resolved in all three deep high resolution datasets, and appears as an irregular galaxy with two close components in the Ks-band images (separation ~0.3"). Given the small impact parameter (b = 19.6 kpc, at z_(lls) = 2.531), as well as the red color of (J — Ks)_(Vega)~1.6,it might be a candidate galaxy giving rise to the Lyman Limit system absorption at Z_(abs) = 2.531 seen in the QSO spectrum. After carefully subtracting the point spread function from the QSO images, the host galaxy of this bright radio quiet QSO at z ?3 was marginally revealed. We placed a lower limit on the host component of m_k ?23.3 according to our analyses.
