Selected publications
A few recent highlights. For the full list, see Google Scholar, NASA ADS, ORCID or my CV.
-
Sparse lensing samples give up almost no cosmological information, and are small enough to calibrate with spectra of a representative subset.
-
DES lensing analyzed with first-principles theory shows no tension with the CMB, even with evolving dark energy.
-
A new way to use small-scale lensing data without being biased by uncertain astrophysics, with a public JAX pipeline.
-
How many N-body simulations it takes to build percent-accurate emulators for future surveys.
-
Tracks how structure grew in the recent universe, including a growth measurement from galaxy magnification.
-
DESI galaxies combined with DES lensing give a clustering amplitude consistent with the CMB.
-
A simulation suite and public emulator for galaxy clustering and lensing predictions, including massive neutrinos.
-
Removes most of the statistical noise from simulation predictions at almost no extra cost.
