Lensing as a Probe of Cosmology

Main Collaborators: J. Rhodes, R. Massey, Euclid Colaboration

Euclid Project Page

Gravitational lensing can be used to measure the growth of structure in the universe, and hence probe the properties of dark matter and dark energy. I was a member of the team that made the first 3-dimensional map of dark matter in the COSMOS field and am a member of the Euclid consurtium which was recently selected by ESA to launch a satelite in 2019. The Euclid satelite will measure the properties of dark matter and dark energy by obtaining optical and near-infrared imaging and spectroscopy for ~15,000 square degrees of sky. I am also an external collaborator on the Hyper-Suprime-Cam project that has similar aims to Euclid. I am actively developing photometric redshift techniques to enable the science for these projects.

Lensing as a Probe of Galaxy Formation

Main Collaborators: A. Lethaud, R. Massey, J. Rhodes

Galaxy-Galaxy lensing is a unique way to link galaxy properties with the dark matter haloes that surround galaxies. Weak galaxy-galaxy lensing is particularily powerful when applied to lare area space based surveys such as COSMOS becasue it provides a halo mass estimate for relatively small samples of galaxies.
