Session 3 - Evolution of Galaxies & Clusters of Galaxies.
Display session, Monday, June 09
South Main Hall,
We present preliminary results of a test of competing scenarios for the formation of dusty optical filaments in the dominant galaxies at the centers of some cluster cooling flows. Two models are compared: the capture or disruption of gas-rich galaxies (Sparks, Ford amp; Kinney 1993) and the standard cooling flow condensate model (Mathews amp; Bregman 1978). The pros and cons of each model are discussed based on detailed morphological analysis of filaments and their possible association with galaxies in Abell 1795 and Abell 426.
