On the nature of star formation in cooling flow ellipticalsWe present evidence based on narrow band optical and near-IR imaging that field and cluster cooling flow galaxies are enriched in low mass stars as a result of recent, truncated IMF star formation from accreting gas. We imaged 25 normal and 6 cooling flow ellipticals using a narrow blue band system. All galaxies have similar mean colors and color gradients. Near IR surface photometry was obtained for three normal ellipticals, three cooling flow ellipticals, and three cluster cooling flows.
