Primordial non-Gaussianity -- the effects of relativistic and wide-angle corrections to the power spectrum
Sêcloka L. Guedezounme, Sheean Jolicoeur, Roy Maartens
Wide-angle and relativistic corrections to the Newtonian and flat-sky approximations are important for accurate modeling of the galaxy power spectrum of next-generation galaxy surv…

Relativistic and wide-angle corrections to galaxy power spectra
Sheean Jolicoeur, Sêcloka L. Guedezounme, Roy Maartens +3
Galaxy surveys contain information on the largest scales via wide-angle and relativistic contributions. By combining two different galaxy populations, we can suppress the strong co…
