Imprints of local lightcone projection effects on the galaxy bispectrum. III.

Roy Maartens, Obinna Umeh, Sheean Jolicoeur, Chris Clarkson

The galaxy bispectrum is affected on super-equality scales by relativistic observational effects, at linear and nonlinear order. These lightcone effects include local contributions from Doppler and gravitational potential terms, as well as integrated contributions like lensing, together with all the couplings at nonlinear order. We recently presented the correction to the galaxy bispectrum from all local lightcone effects up to second order in perturbations. Here we update our previous result by including the impact on the nonlinear lightcone effects from relativistic dynamical evolution.
