Euclid preparation. XLI. Galaxy power spectrum modelling in real space
Euclid Collaboration, A. Pezzotta, C. Moretti +246
We investigate the accuracy of the perturbative galaxy bias expansion in view of the forthcoming analysis of the Euclid spectroscopic galaxy samples. We compare the performance of…
Flat-sky Angular Power Spectra Revisited
Zucheng Gao, Zvonimir Vlah, Anthony Challinor
We revisit the flat-sky approximation for evaluating the angular power spectra of projected random fields by retaining information about the correlations along the line of sight. W…
On the asymptotic connection between full- and flat-sky angular correlators
Zucheng Gao, Alvise Raccanelli, Zvonimir Vlah
We investigate the connection between the full- and flat-sky angular power spectra. First, we revisit this connection established on the geometric and physical grounds, namely that…
The observed power spectrum & frequency-angular power spectrum
Alvise Raccanelli, Zvonimir Vlah
The two-point summary statistics is one of the most commonly used tools in the study of cosmological structure. Starting from the theoretical power spectrum defined in the 3D volum…
Optimizing the Evolution of Perturbations in the CDM Universe
Nicholas Choustikov, Zvonimir Vlah, Anthony Challinor
Perturbation theory is a powerful tool for studying large-scale structure formation in the universe and calculating observables such as the power spectrum or bispectrum. However, b…
Effective Field Theory of Intrinsic Alignments at One Loop Order: a Comparison to Dark Matter Simulations
Thomas Bakx, Toshiki Kurita, Nora Elisa Chisari +2
We test the regime of validity of the effective field theory (EFT) of intrinsic alignments (IA) at the one-loop level by comparing with 3D halo shape statistics in N-body simulatio…
