Multipoles of the relativistic galaxy bispectrum
Eline M. de Weerd, Chris Clarkson, Sheean Jolicoeur +2
Above the equality scale the galaxy bispectrum will be a key probe for measuring primordial non-Gaussianity which can help differentiate between different inflationary models and o…
Detecting the relativistic galaxy bispectrum
Roy Maartens, Sheean Jolicoeur, Obinna Umeh +3
The Fourier-space galaxy bispectrum is complex, with the imaginary part arising from leading-order relativistic corrections, due to Doppler, gravitational redshift and related line…
The galaxy bias at second order in general relativity with Non-Gaussian initial conditions
Obinna Umeh, Kazuya Koyama
We present a systematic study of galaxy bias in the presence of primordial non-Gaussianity in General Relativity (GR) at second order in perturbation theory. The non-linearity of t…
General relativistic effects in the galaxy bias at second order
Obinna Umeh, Kazuya Koyama, Roy Maartens +2
The local galaxy bias formalism relies on the energy constraint equation at the formation time to relate the metric perturbation to the matter density contrast. In the Newtonian ap…
