Imprints of local lightcone projection effects on the galaxy bispectrum. Part III. Relativistic corrections from nonlinear dynamical evolution on large-scales
Jolicoeur, S; Umeh, O; Maartens, R; Clarkson, C (IOP Publishing, 2018-03-01)The galaxy bispectrum is affected on equality scales and above by relativistic observational effects, at linear and nonlinear order. These lightcone effects include local contributions from Doppler and gravitational potential ...
