Local primordial non-Gaussianity in the relativistic galaxy bispectrum
Roy Maartens, Sheean Jolicoeur, Obinna Umeh +2
Next-generation galaxy and 21cm intensity mapping surveys will rely on a combination of the power spectrum and bispectrum for high-precision measurements of primordial non-Gaussian…

Detecting the relativistic bispectrum in 21cm intensity maps
Sheean Jolicoeur, Roy Maartens, Eline M. De Weerd +3
We investigate the detectability of leading-order relativistic effects in the bispectrum of future 21cm intensity mapping surveys. The relativistic signal arises from Doppler and o…
