The daughter of Vera Rubin. Judy's major area of astronomical research was extragalactic observations of star-forming molecular gas using CO lines and related observations of star formation tracers in blue light, H-alpha emission, and the infrared continuum. Her molecular observations were made with the 14 m single dish FORAO telescope. The initial imaging of nearby spiral galaxies, in collaboration with Nick Scoville, then at UMass, first clearly demonstrated the proportionality of the star formation rate surface density to the molecular gas. They also first showed the efficacy of using the CO emission line as a tracer of the molecular gas mass. Subsequent surveys of CO and star formation led by Judy were conducted with her PhD students and post-docs over the following decades - 1982-2001. These projects included a survey with Linda Tacconi of late-type spirals and dwarf galaxies; an extensive survey probing the depletion of HI and H2 in Virgo cluster galaxies with leff Kenney; and some of the first observations of CO in ULIRG galaxies with Dave Sanders and Nick Scoville. She also led the FCRAO Extragalactic CO Survey, having major participation from Nick Devereux, Pat Knezek, Shuding Xie, and Lori Allen in addition to those mentioned earlier. This survey included CO mapping for 300 low-redshift galaxies; and despite the enormous number of objects, it was a characteristic of Judy to know every detail of each galaxy and to love them as family.
