In the local universe, the masses of giant black holes are correlated with the luminosities, masses and velocity dispersions of their host galaxy bulges. This indicates a surprisingly close connection between the evolution of galactic nuclei (on parsec scales) and of stars on kpc scales. A key observational test of proposed explanations for these correlations is to measure how they have evolved over cosmic time. Our ACS imaging of 20 Seyfert 1 galaxies at z=0.37 showed them to have smaller bulges (by a factor of 3) for a given central black hole mass than is found in galaxies in the present-day universe. However, since all our sample galaxies had black hole masses in the range 10^8.0--8.5 Msun, we could only measure the OFFSET in black hole mass to bulge luminosity ratios from the present epoch. By extending this study to black hole masses another factor of 10 lower, we propose to determine the full CORRELATION of black hole mass with host galaxy properties at a lookback time of 4 Gyrs and to test mass-dependency of the evolution. We have selected 14 Seyfert galaxies from SDSS DR5 whose narrow Hbeta emission lines (and estimated nuclear luminosities) imply that they have black hole masses around 10^7 Msuns. We will soon complete our Keck spectroscopic measures of their bulge velocity dispersions. We need a 1-orbit NICMOS image of each galaxy to separate its nonstellar luminosity from its bulge and disk. This will allow us to make the first determination of the full black hole/bulge relations at z=0.37 (e.g. M-L and M-sigma), as well as a test of whether active galaxies obey the Fundamental Plane relation at that epoch.

Our goal is to obtain high resolution photometry of a sample of 14 Seyfert 1 galaxies at z=0.37+-0.01 for which central black hole masses and bulge velocity dispersions are obtained from the ground. We need to determine the luminosity of the bulge and of the central point source, in order to extend our measurement of the M-L and M-sigma relationships down to black hole mass ~10^7 solar mass. We aim for uncertainties on the photometric quantities smaller than 0.2 dex, i.e. small with respect to the intrinsic uncertainty on the virial black hole mass estimates (0.4 dex). In addition, we will also derive effective radii (Re) and effective surface brightnesses (SBe) for the bulges, in order to derive their dynamical masses (sigma^2 Re) and probe the evolution of relationships involving more than one variable. Strategy The following strategy is based on our previous successful experience (Cycle 13). Camera. NIC-2 on NICMOS is the camera of choice, providing superior sensitivity to the NIC-1 camera at the low surface brightness levels needed to do bulge/disk decomposition, and better PSF sampling than NIC-3. PSF sampling will be further improved by obtaining dithered exposures with semi-integer pixel offsets (4 positions per pixel). This will also enable robust cosmic ray/defects removal. Note that the contrast between the central point source and the host galaxy in our sample is far more favorable than in other HST studies of QSOs hosts, where the AGN typically outshines the galaxy by a factor of 10 or more. Furthermore going to longer wavelength improves the contrast, since the host is redder than the nucleus. Therefore, in our case the modelling of the wings of the PSF is not nearly as crucial to obtain accurate parameters for the host galaxy. The residual PSF related uncertainties are estimated as described below. Filter. To minimize the size of the PSF, and preserving high sensitivity, we select the F110W filter. This filter is close in wavelength to the rest frame 5100\AA\ continuum -- used to estimate the size of the broad line region. Exposure time. The depth of the observations is chosen to obtain data of comparable quality to the ones we have obtained in Cycle 13 (adequate to meet our goals). Based on our previous extensive experience with structural parameters of distant bulges and AGN (e.g. Hunt et al.\ 1999; Treu et al. 2001), and confirmed by our study from Cycle 13 data (Treu et al. 2007), the limiting factor is the signal to noise at the relatively low surface brightness typical of the disk and the outer bulge. The typical surface brightness of the outer bulge region is I=22 mag arcsec$^{-2}$ , corresponding to F110W$\sim$20.8 mag arcsec$^{-2}$ (Vega). According to the NICMOS ETC, surface brightness I=22 mag arcsec$^{-2}$ gives signal-to-noise ratio of 10 per 1x1 pixel area in 2300s using the F110W filter (i.e. one orbit per pointing, 4 exposures per pointing and related overhead), which is adequate for our goals. The same exposures will yield extremely high signal-to-noise ratio detection (S/N$>200$) of the central point source, allowing for accurate determination of its luminosity, and the wings of the PSF. NICMOS-PSF with the F110W filter is ~50% larger than ACS-PSF in optical bands. However, stellar-to-AGN flux ratio is higher in near IR than optical. Thus, we will be able to resolve host galaxy bulges.
