What can galaxy shapes tell us about physics beyond the standard model?
The shapes of galaxies trace scalar physics in the late-Universe through the large-scale
gravitational potential. Are they also sensitive to higher-spin physics? We present a general …

Bayesian mass mapping with weak lensing data using karmma: Validation with simulations and application to Dark Energy Survey year 3 data
SS Boruah, P Fiedorowicz, E Rozo - Physical Review D, 2024 - APS
We update the field-level inference code karmma to enable tomographic forward-modeling
of shear maps. Our code assumes a log-normal prior on the convergence field, and properly …
