Abstract

We present WFPC2 images of the core of the cooling flow cD galaxy in Abell 1795. An irregular, asymmetric dust lane extends 7 h75-1 kpc in projection to the north-northwest. The dust shares the morphology observed in the Ha and excess UV emission. We see both diffuse and knotty blue emission around the dust lane, especially at the ends. The dust and emission features lie on the edge of the radio lobes, suggesting star formation induced by the radio source or the deflection of the radio jets off of preexisting dust and gas. We measure an apparent Rv significantly less than 3.1, implying that the extinction law is not Galactic in the dust lane, or the presence of line emission that is proporti..
