Our spectroscopic survey of 900 nearby galaxies has already yielded one of the most massive black holes in a remarkably compact galaxy NGC1277. Now we propose to obtain imaging of a nearby galaxy which may host the most massive black hole found to date. This galaxy, UGC2698, lies nearby at a distance of 89 Mpc and has an average size and luminosity, and a extremely high central velocity dispersion of 440 km/s, indicative of black hole mass in excess 10 billion solar masses. With one orbit, we can resolve its small bulge and put accurate constraints on its black hole mass (in combination with our spectroscopy). If this system also contains a very high black hole mass, it would be in stark conflict with the popular co-evolution picture. Imaging of UGC2698 a nearby (~90 Mpc) early-type galaxy. We expect this systems to be extremely cuspy and have high central surface brightnesses (V~13.7 Mag/arcsec^2), half-light radii of a 3-6 arcseconds and a total diameter of ~60 arcseconds, based on archival HST observations of two proptotypical galaxies (NGC1277 and NGC4486B) and our cycle 20 program 13050. The exposures are driven by the following: 1 Obtain a high resolution image of the galaxy (nucleus). This allows us to make a stellar luminosity (mass) model of the whole galaxy, which is needed as input for the dynamical model. 2 Obtain an image in a second band to constrain the color (gradient), which allows us to look for nucleur dust & clusters and stellar population gradients. 3 Given the large extent, we need full frame read outs to determine the background levels, especially in the IR. 4 Obtain a surface brightness fluctuation (SBF) distance. CHOICE OF FILTERS: Given that these targets are further away than the Virgo cluster, we chose F160W in the proposal as the SB fluctuations are strongest in this band (Blakeslee et al.). To augment the F160W band we chose F814W as there are SBF calibrations available in the F814W-F160W color and F814W is a very efficient filter. EXPOSURE TIMES: To probe the outer part of the galaxies (~24.7 Vmag/arcsec^2) we need at least 700+ seconds with F814W. To determine SBF distances for distances over 80 Mpc, exposure times over 1500 seconds in F160W are needed (Blakeslee priv. comm.). Saturation in the F160W is a concern. If these galaxies have bright central cusps (Like N1277 and N4486B), we expect the IR detector to saturate in ~3 seconds. OBSERVING PLAN: 3 dithers (STEP50,NSAMP=14) with F160W to cover the whole galaxy and estimate the background. To avoid saturation in the subsequent exposures, we use the WFC3-IR-DITHER-BOX-UVIS pattern. 4 RAPID NSAMP=15 SUB128 dithers with the WFC3-IR-DITHER-BOX-MIN pattern to obtain a high resolution, to be able to determine the color-profile of the nucleus. 3 dithers (165+300+350sec, pattern B3) in F814W to obtain (nearly) diffraction limited of the galaxy.
