As part of the Selected Areas Starcount Survey (SASS), a CCD survey to V > 21, we have obtained V I photometry of two fields at b = ±40 • aligned roughly with an extrapolation of the major axis of the Sagittarius (Sgr) dwarf spheroidal galaxy. Comparison of the color-magnitude diagram (CMD) for some of these fields to the CMDs of fields reflected about the(More)
Applying a voltage difference between a conductor and a sessile droplet sitting on a thin dielectric film separating it from the conductor will cause the drop to spread. When the conductor is a good metal, the change of the drop's contact angle due to the voltage is given the Young-Lippmann equation. Here we report experiments with lightly-doped, single(More)
