| 英文摘要 | We have obtained deep J and Ks-band images centered on a bright radio quiet QSO UM402 (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 similar to 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 similar to 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) similar to 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 similar to 3 was marginally revealed. We placed a lower limit on the host component of m(k) similar to 23.3 according to our analyses. |
