[21.14] The Nuclear Stellar Dynamics of the S0 Galaxy NGC7332

C.H. Nelson, D. Weistrop (UNLV), G. A. Bower, R. F. Green (NOAO/KPNO), STIS Team

STIS near-IR longslit spectroscopy of the nearby S0 galaxy NGC 7332 was obtained of the Ca II triplet absorption lines at ~8600 Å. We use the Fourier correlation quotient method (Bender 1990, A&Ap, 229, 441) to extract the line-of-sight velocity distribution in the inner 4\prime \prime of the galaxy. Combined with ground-based imaging and spectroscopy (Fisher, Illingworth & Franx 1994, AJ, 107, 160) and HST WF/PC-1 imaging (Lauer et al. 1995, AJ, 110, 2622) these data were fitted with three-integral dynamical models developed by K. Gebhardt, to investigate the nuclear stellar dynamics and to search for evidence of a massive black hole. Since Maggorian et al. (1998, AJ, 115, 2285) find it to be the best case for M\bullet=0, NGC 7332 is an important object.
