Scientific paper

We report our search for the cool white dwarfs belonging to the Galactic disk by extending the NOAO Deep Wide-Field Survey. Narrow-band DDO51 photometry of the Deep Wide-Field Survey's northern field was obtained using the 4m-Mayall Telescope and the MOSAIC imager to separate cool white dwarfs from other stellar types of similar T_eff. Follow-up spectroscopy of four white dwarf candidates from our photometric search resulted in the discovery of two new cool white dwarfs as companions to M dwarfs.
