The NOAO Deep Wide-Field Survey

RESEARCH INTERESTS

My current research interests include the formation, assembly and evolution of galaxies over cosmic time. To measure the assembly history of galaxies, I measure the evolving space density and clustering of distant galaxies using large imaging and spectroscopic surveys, including the NOAO Deep Wide-field Survey (NDWFS), the Spitzer IRAC Shallow Survey, and the AGES spectroscopic survey.

In my most recent first author paper, The Evolving Luminosity Function of Red Galaxies, I traced the assembly history of red galaxies over the past 8 billion years. Blue star-forming galaxies are being transformed into red galaxies, with little ongoing star formation, between redshifts of z=1 and z=0. In contrast, the stellar masses of the most massive galaxies exhibit modest evolution over the same redshift range. While there is some ongoing assembly of red galaxies, the stellar masses of the most massive galaxies evolve slowly at low redshift.

I frequently work in collaboration with Buell Jannuzi, Arjun Dey, Kate Brand and other NDWFS team members. Other recent publications with the NDWFS collaboration include The Infrared Luminosity Function of Type I Quasars and The Clustering of Extragalactic Extremely Red Objects. Much of the NDWFS data is available from the NDWFS website and along with a full list of NDWFS publications.
