Abstract The discovery by Franx and Illingworth of a kinematically-distinct stellar core in the nucleus of the giant radio elliptical IC 1459, and the confirmation that such components are quite common, has added a valuable diagnostic tool for understanding the structure and the formation of ellipticals. These cores are substantial (10**10 solar masses for IC 1459) and offer a valuable and unique diagnostic of the dynamical state of the nuclei of ellipticals. Further study will address their formation by investigating whether these cores could be the end result of a `starburst' event, or from the capture of a stellar companion, or even the merging of primordial subclumps. Here we propose to take advantage of the high resolution imaging of the PC to image the 16 galaxies with known kinematically distinct cores from our magnitude limited sample of 77 ellipticals. The focus of the program is the detection of stellar disks (as suggested by the spectroscopic line profile analysis) and color differences between the core region and the rest of the galaxy. If the cores have been affected by accretion of stars or gas, and star formation, then such differences are naturally expected. This program also allows us to identify the color of any jets or shells and map the dust at small radii. These data are an essential complement to our extensive ground-based spectroscopic and imaging survey. ------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------ 9.

Description of proposed observations. We propose to observe all 16 ellipticals with known kinematically distinct cores from our magnitude limited sample of 77 galaxies. Several of the galaxies are of special interest. IC 1459 because it is one the most extreme examples of a galaxy with a kinematically distinct core. NGC 7626 is remarkable because it has a very irregular rotation curve(1). It is very well possible that the central parts are not fully relaxed. It will be very interesting to see whether HST detects any sharp, high contrast features in this galaxy. NGC 1439 is the intrinsically faintest galaxy in the sample, with the lowest velocity dispersion. NGC 1427 has a rotation curve that is unresolved even at subarcsecond seeing. NGC 5982 is the only galaxy which has a distinct core that has a rotation axis parallel to the major axis. All other systems rotate around the minor axis. We propose to obtain sets of images in the F555W and F814W filters. The F555W filter is chosen for this study because it provides high throughput and its PSF will be well monitored. This is important for removing a nuclear point source prior to further analysis (as was necessary for IC 1459) and if deconvolution is applied. The F814W filter provides a long wavelength base for color analysis (it is less affected by dust), the background sky is fainter (Wright 1985) and better samples the dominant stellar component. Although we expect WFPC2 to have an image quality close to specifications (i.e. 70% in 0.1''), we can still in principle gain through deconvolution techniques with imaging closer to the diffraction limit of the telescope (i.e. 80% in 0.1''). 1. Jedrzejewski Schechter 1988, ApJ, 330, L87 Page 3 ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The use of the imaging capabilities of HST is a logical and important component of a broadly-based observational program involving ground-based long-slit spectra and ground-based images of ellipticals with kinematically-distinct cores. Both the spectroscopic and the imaging results suggest that these distinct nuclear subcomponents are unresolved from the ground in typical 1-2'' seeing. The cores of ellipticals are known to be at best marginally resolved from the ground, with a few notable exceptions (see e.g., ref. 1). If compact star clusters or black- holes are significant in these cores, the small gains in resolution possible at Hawaii and other sites will not be decisive in establishing the structure of the nuclei on scales <0.2''. The results by Lauer et al (ref. 2,3,4) have shown convincingly that PC imaging can do significantly better than any ground-based facilities. The images requested here will complement the available ground-based multicolor CCD surface photometry by allowing comparison of the core structure and properties with those at larger radii. Furthermore, the early `discovery' spectroscopic observations have been supplemented by a set of higher S/N long- slit spectra taken with the highest practical ground-based spatial resolution (1'' with 0.3-0.6'' pixels) at a variety of position angles. These data have been acquired both in the Northern and Southern hemispheres, at CTIO and Lick. The use of the imaging capabilities of HST is a logical and important component Ideally one would like high spatial resolution spectroscopic observations from HST. This is impractical without a good imaging capacity and without a long-slit spectrograph on HST; the FOS integrations required would be prohibitively long. The best approach is the compromise one of high resolution HST images, combined with ground-based kinematical mapping and overlapping with ground-based images that define the large-scale (r > 5-10'') structure. 1.

The PI (MF) and Co-I (GDI) have been involved in several previous HST programs. They include: 2684 (The Medium Deep Survey), GDI. 4664 (Nearby Nuclei Snapshot Survey), GDI. 3551 (Ellipticals with Kinematically Distinct Nuclei), GDI and MF. 2227 and 3905 (The Extra-Galactic Distance Scale), GDI. The most directly related program is 3551 from cycle 2. This was a single color (F555W) PC imaging project of seven galaxies with kinematically distinct cores. In our paper (Illingworth, Forbes Franx 1993, in preparation) we report that IC 1459 reveals an unresolved point source (V 18.5mag), a cusp to the central starlight profile (with a slope similar to that found for M87) and a small scale dust lane that appears to reach into the very nucleus and may thus be associated with material that fuels the nuclear activity. Reduction and analysis of the other six galaxies are in progress. Although this data contains much useful information on small scales, it provides no color information which is the main focus of this proposal. The data requested here will also benefit from the improved optics allowing more subtle features, than present in IC 1459, to be revealed. Program 4664 involved short, single color (F555W) exposures of nearby SO and spiral nuclei. Although it is related in general aim (to probe the nuclear region of galaxies unavailable to ground-based observations) this program can not address the specific areas that can be tackled with the multi-color data requested in this proposal.

Forbes, Illingworth Franx 1993, in preparation (July 93). Griffiths et al. 1993, Science with the HST, in press. There have also been various abstracts published from talks and posters at AAS meetings. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). Most of the data reduction will be carried out at Lick Observatory. Lick Observatory has a strong foundation for image processing of large HST images (via the Medium Deep Survey key project and WFPC IDT). The department has a powerful host SUN 4/280 system with high performance peripherals. Both GDI and DAF have UCSC-supplied SUN workstations, which will draw upon the departmental resources. Several staff are available to support the systems and system software development. There is also a pool of ten or more graduate students, some of whom have University Fellowships, who work intensively with optical imaging and spectroscopy. S. Faber, an WFPC IDT team member, is on the Lick faculty, and will be a source of the IDT team's valuable early experience in processing WFPC data. GDI also has access to the 3 m and 1 m telescopes on Mt. Hamilton, and to the Keck 10m. MF, previously a Hubble Fellow, is now a full Professor at the Kapteyn Astronomical Institute. This position includes summer salary, and some research funding. The Kapteyn Institute is involved in several HST GO programs. ------------------------------------------------------------------------------------ 11.
