The observable statistics
Basundhara Ghosh, Ruth Durrer
Recently Moradinezhad Dizgah & Durrer have shown that the statistics, useful to test theories of modified gravity, is plagued by additional scale and bias dependent lensing c…
The Full-Sky Angular Bispectrum in Redshift Space
Enea Di Dio, Ruth Durrer, Roy Maartens +2
We compute the redshift-dependent angular bispectrum of galaxy number counts at tree-level, including nonlinear clustering bias and estimating numerically for the first time the ef…
Bias and scatter in the Hubble diagram from cosmological large-scale structure
Julian Adamek, Chris Clarkson, Louis Coates +2
An important part of cosmological model fitting relies on correlating distance indicators of objects (for example type Ia supernovae) with their redshift, often illustrated on a Hu…
Tensor Bounds on the Hidden Universe
Adrian del Rio, Ruth Durrer, Subodh P. Patil
During single clock inflation, hidden fields (i.e. fields coupled to the inflaton only gravitationally) in their adiabatic vacua can ordinarily only affect observables through virt…
Intensity mapping of the 21cm emission: lensing
Mona Jalilvand, Elisabetta Majerotto, Ruth Durrer +1
In this paper, we study lensing of 21cm intensity mapping (IM). Like in the cosmic microwave background (CMB), there is no first order lensing in intensity mapping. The first effec…
Redshift-space distortions from vector perturbations II: Anisotropic signal
Vittorio Tansella, Camille Bonvin, Giulia Cusin +3
We study the impact on the galaxy correlation function of the presence of a vector component in the tracers' peculiar velocities, in the case in which statistical isotropy is viola…
