The observed galaxy bispectrum from single-field inflation in the squeezed limit
(IOP Publishing, 2018)
Using the consistency relation in Fourier space, we derive the observed galaxy bispectrum from
single- eld in
ation in the squeezed limit, in which one of the three modes has a wavelength much
longer than the other two. ...
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 ...
