Code & data
The estimators behind my papers are public on GitHub under the MIT license. Each one turns a different kind of cosmological data into bispectrum measurements: galaxy fields for BARBIE, and radio-interferometer visibilities for ViBER and AMBER.
Galaxy surveys
Brisk estimator for Angular multipoles of Redshift-space BIspEctrum
Takes a 3D cube of the galaxy density field and computes all the multipole moments of the redshift-space bispectrum, with redshift-space distortions taken along the z-axis.
21-cm cosmology
Visibility-based angular Bispectrum Estimator for Radio-interferometric data
Works on gridded visibilities from a single frequency channel and computes the angular bispectrum by correlating every triplet of baselines that closes into a triangle.
21-cm cosmology
Accelerated multi-frequency angular and 3D bispectrum estimator
Extends the visibility-based approach across frequency. From gridded multi-frequency visibilities, it computes three-visibility correlations for every closed triangle of baselines, giving the multi-frequency angular bispectrum (MABS) and the 3D bispectrum.
Data release
