Scientific paper

We report an analysis of stellar populations based on color gradients for a large sample of nearby S0 and early-type spiral galaxies. The color gradients are constructed from deep near-IR (JH bands) and optical images. The IR images were collected with ULBCAM at the UH 2.2-m telescope. The optical (griz) photometric data are taken from the Sloan Digital Sky Survey (SDSS). U-band data is obtained from the SOAR Optical Imager, along with B and R-band data. Deep surface brightness profiles, extending out to 3-4 disk scale lengths, are extracted from the ULBCAM, SDSS, and SOI images. The galaxy colors are compared to the stellar population synthesis models of Bruzual & Charlot, revealing radial trends of ages and metallicities of stellar populations in the bulge and disk. This is the largest study of its kind to date (for S0 galaxies). This study was funded by NSF grant AST-04-06443 to the University of North Carolina.
