This program is part of QUEST (Quasar/ULIRG Evolution Study) and complements a similar set of data on 26 highly nucleated ULIRGs presented in Paper I (Veilleux et al. 2006ApJ...643..707V). Our analysis indicates that the fraction of QSOs with elliptical hosts is higher among QSOs with undetected far-infrared (FIR) emission, small infrared excess (LIR/LB<10), and luminous hosts. The hosts of FIR-faint QSOs show a tendency to have less pronounced merger-induced morphological anomalies and larger QSO-to-host luminosity ratios on average than the hosts of FIR-bright QSOs, consistent with late-merger evolution from FIR-bright to FIR-faint QSOs. Description: The methods used to acquire, reduce, and analyze the present data are nearly identical to those of Paper I (Veilleux et al. 2006ApJ...643..707V) in which we reported the results from a Cycle-12 HST NICMOS H-band imaging survey of 26 z<0.3 ULIRGs and seven infrared-bright Palomar-Green (PG) QSOs. The combined sample of 28 PG QSOs successfully observed during Cycles 12 and 15 covers the low-redshift and low B-band luminosity ends of the PG QSO sample (see Figure 2 of Veilleux et al. 2009, Cat. J/ApJS/182/628). File Summary:

Note (1): Entries for this object are uncertain because the host galaxy fills most of the field of view, so the sky background is not well determined. Note (2): Morphological classes are: E = elliptical, B+D = bulge+disk, D = disk, A = ambiguous. Question marks ("?") indicate uncertain classification due to PSF mismatch (see sections 3 and 4.1). Note (3): IVb = compact merger, V = old merger; see Veilleux et al. 2002, Cat. J/ApJS/143/315, section 3.4, for details on the definitions.
