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

Understand

General relativistic imprints on the galaxy bispectrum arise from observational (or projection) effects.

• The lightcone projection effects include local contributions from Doppler and gravitational potential terms, as well as lensing and other integrated contributions.
• We recently presented for the first time, the correction to the galaxy bispectrum from all local lightcone projection effects up to second order in perturbations.
• Here we provide the details underlying this correction, together with further results and illustrations.
