1995AJ....109.1608R NEAR-INFRARED SURFACE PHOTOMETRY AND MORPHOLOGY IN VIRGO CLUSTER SPIRAL GALAXY NUCLEAR REGIONS BERNARD J. RAUSCHER The University of Chicago, Department of Astronomy and Astrophysics, 5640 South Ellis Avenue, Chicago, Illinois 60637 Electronic mail: bjr@oddjob.uchicago.edu Received 1994 August 17; revised 1994 November 14 ABSTRACT This paper presents very high spatial resolution (seeing 0.75 arcsec FWHM) K band surface photometry of 15 Virgo cluster spiral galaxy nuclear regions (radii < 1 kpc). It presents B and J band CCD images of 13 of these galaxies. The goals of the study were: (1) to begin to establish a K band baseline of normal spiral galaxy nuclear regions against which peculiar galaxies may be compared, (2) to provide better constraints on N-body models, and (3) to complement near-infrared studies of large scale structure in spiral galaxies with very high resolution imaging of the important nuclear regions. The principal findings are: (1) between 1/4 and 1/3 of these nuclear regions show K band evidence of triaxiality, (2) approximately 1/2 of these galaxies have axisymmetric nuclear regions, and (3) NGC 4321 has a bar that is not detectable in the optical images.
