Detecting the relativistic galaxy bispectrum
(IOP Publishing Ltd, 2020)
The Fourier galaxy bispectrum is complex, with the imaginary part arising from
leading-order relativistic corrections, due to Doppler, gravitational redshift and related lineof-sight effects in redshift space. The detection ...
Constraining primordial non-Gaussianity by combining next-generation galaxy and 21 cm intensity mapping surveys
(Institute for Ionics, 2023)
Surveys of the matter distribution contain ‘fossil’ information on possible non-Gaussianity that is generated in
the primordial universe. This primordial signal survives only on the largest scales where cosmic variance ...
