Research Interests: Professor Wittman has discovered millions of galaxies as co-PI of the Deep Lens Survey, which was awarded over 100 nights on 4-m telescopes to study a representative sample of the universe.
2017. First results on shear-selected clusters from the deep lens survey: Optical imaging, spectroscopy, and X-ray follow-up. D Wittman, IP Dell’Antonio, JP Hughes, VE Margoniner, JA Tyson, ...

David Wittman at UC Davis. High-redshift cluster of galaxies discovered through its gravitational effects alone, in the Deep Lens Survey.
Instructor: David Wittman ... For lensing by clusters, read section 3 of Mellier 1999 (but skipping 3.3 if you wish) and section 2 of Wittman 2002.
Prof. David Wittman was awarded 8 orbits of Hubble Space Telescope time to study collisions of galaxy clusters. These are the largest masses in the universe and a large fraction of their mass is dark matter.
I am currently focused on the Deep Lens Survey (DLS), a deep optical imaging survey of 20 square degrees of sky. As Co-PI, I am deeply involved in all aspects of the survey, from planning and coordinating over 100 nights of 4-meter telescope time, to data processing and algorithms, to final science analysis and public data release.
Jun 29, 2023 · A mathematician working in the life sciences and an astrophysicist studying dark matter from the College of Letters and Science at UC Davis are among the recent cohort awarded Chancellor’s Fellowships for Diversity, Equity and Inclusion.
