Statistical Field Theory for Weak Gravitational Lensing
Zheng Zhang, Philip Bull, Chris Clarkson +1
Standard weak-lensing calculations treat lensing as a linear remapping of the matter field along the line of sight. We instead formulate lensing as a stochastic field theory for th…
The observer power spectrum for lightcone statistics, integrated relativistic observables and wide angle effects
Chris Clarkson, Pritha Paul
The statistics of large-scale structure are naturally described by power spectra in Fourier space. For fields on spatial hypersurfaces, translational invariance makes different Fou…
Multi-tracer power spectra and bispectra: Formalism
Dionysios Karagiannis, Roy Maartens, José Fonseca +2
The power spectrum and bispectrum of dark matter tracers are key and complementary probes of the Universe. Next-generation surveys will deliver good measurements of the bispectrum,…
The observed number counts in luminosity distance space
José Fonseca, Stefano Zazzera, Tessa Baker +1
Next generation surveys will provide us with an unprecedented number of detections of supernovae Type Ia and gravitational wave merger events. Cross-correlations of such objects of…
Theoretical systematics in testing the Cosmological Principle with the kinematic quasar dipole
Caroline Guandalin, Jade Piat, Chris Clarkson +1
The Cosmological Principle is part of the foundation that underpins the standard model of the Universe. In the era of precision cosmology, when stress tests of the standard model a…
Wide-angle effects in multi-tracer power spectra with Doppler corrections
Pritha Paul, Chris Clarkson, Roy Maartens
We examine the computation of wide-angle corrections to the galaxy power spectrum including redshift-space distortions and relativistic Doppler corrections, and also including mult…
