A few percent of quasars show strong narrow MgII associated absorption lines (AALs) lying close to the rest frame of the quasar. Recent results show that quasars with AALs (AALQSOs) have distinct host galaxy properties, with higher star formation rate and more dust reddening than classical quasars, but less dust reddening than heavily dust-reddened quasars. These results suggest that the bulk of AALs are intrinsic to the quasar and its host galaxy, and AALQSOs may be the transitional population from dust-enshrouded to classical quasars in the Sanders & Mirabel picture of quasar evolution. This scenario predicts that AALQSO hosts should have a larger fraction of young bulges, disturbed morphologies and interactions compared with classical quasars. We propose to image a sample of 11 z~0.6 AALQSOs with WFC3 IR and UVIS to characterize their host galaxy properties and to test this evolutionary scenario. The host information will also help us constrain the nature of these associated absorbers. Confirming that AALQSOs represent a transitional population would be an important discovery, revealing the missing link between dust-enshrouded quasars and classical quasars, and justifying detailed studies of these associated absorbers to understand the physical conditions and formation processes of quasars and massive host galaxies. We will observe 11 science targets, among which 10 targets will have two orbits (one for WFC3-UVIS observation and one for WFC3-IR observation). Target J0932+4338 will only have one orbit for WFC3-UVIS observation. We divide our targets into two groups, each group will be observed within 0-3 days. For each group we will observe one orbit for a PSF star (GRW+70D5824), with UVIS and IR observations combined in one orbit. This stragety is to facilitate PSF reconstruction for our science targets. The total number of orbits is therefore 23. For the UVIS observations, we will use the 2k subarray with the F475W filter, and the three-point line dither pattern. For the IR observations, we will use the 512 subarray with the F160W filter, and the four-point box dither pattern. Special Scheduling Requirements We request that our grouped targets be observed within a 3-day window. This is to ensure a stable PSF over this short period. Delayed scheduling due to this restriction is OK.
