About

P. Nugent is a leading figure in observational cosmology and time-domain astrophysics, best known for spearheading the BigBOSS Experiment (now DESI), a Stage IV ground-based dark energy survey. This ambitious project, detailed in their highly cited 2011 paper (80 citations), aims to map baryon acoustic oscillations and the growth of cosmic structure across 14,000 square degrees using a wide-area galaxy and quasar redshift survey. Conditionally accepted by NOAO, BigBOSS represents a monumental leap in our understanding of dark energy. Beyond cosmology, Nugent has made innovative contributions to stellar astrophysics, particularly in detecting close-separation binary systems within synoptic sky surveys. Their 2013 work (19 citations) introduced a technique to identify elongated objects beyond the limits of point-spread function calibration, enabling the discovery of millions of unresolved multiples. This dual expertise—bridging large-scale structure surveys and precision stellar characterization—showcases Nugent’s versatility. With a career defined by transformative instrumentation and novel detection methods, their research continues to shape both the cosmic distance scale and the demographics of binary stars in wide-field surveys.
