Disantangling the effects of Doppler velocity and primordial non-Gaussianity in galaxy power spectra
L. Raul Abramo, Daniele Bertacca
We study the detectability of large-scale velocity effects on galaxy clustering, by simulating galaxy surveys and combining the clustering of different types of tracers of large-sc…
Relativistic wide-angle galaxy bispectrum on the light-cone
Daniele Bertacca, Alvise Raccanelli, Nicola Bartolo +3
Given the important role that the galaxy bispectrum has recently acquired in cosmology and the scale and precision of forthcoming galaxy clustering observations, it is timely to de…
Does Quartessence Ease Tensions?
Stefano Camera, Matteo Martinelli, Daniele Bertacca
Tensions between cosmic microwave background observations and the growth of the large-scale structure inferred from late-time probes pose a serious challenge to the concordance …
LIGER: mock relativistic light-cones from Newtonian simulations
Mikolaj Borzyszkowski, Daniele Bertacca, Cristiano Porciani
We introduce a method to create mock galaxy catalogues in redshift space including general relativistic effects to linear order in the cosmological perturbations. We dub our method…
