Context. Weak lensing mass-mapping is a useful tool for accessing the full distribution of
dark matter on the sky, but because of intrinsic galaxy ellipticies, finite fields, and missing …

Most cosmic shear analyses to date have relied on summary statistics (eg ξ+ and ξ−). These
types of analyses are necessarily suboptimal, as the use of summary statistics is lossy. In …

We present a Bayesian velocity field reconstruction algorithm that performs the
reconstruction of the mass density field using only peculiar velocity data. Our method …

Field-level inference is emerging as a promising technique for optimally extracting
information from cosmological data sets. Previous analyses have shown field-based …

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 …

We present miko, a catalog-to-cosmology pipeline for general flat-sky field-level inference,
which provides access to cosmological information beyond the two-point statistics. In the …

The last few years have seen the development of a promising theoretical framework for
statistics of the cosmic large-scale structure—the theory of large deviations (LDT) for …

As a large-scale overdensity collapses, it affects the orientation and shape of galaxies that
form, by exerting tidal shear along their axes. Therefore, the shapes of elliptical galaxies …

Non-Gaussian statistics of the projected weak lensing field are powerful estimators that can
outperform the constraining power of the two-point functions in inferring cosmological …

Weak gravitational lensing is an invaluable tool for understanding fundamental
cosmological physics. An unresolved issue in weak lensing cosmology is to accurately …
