Observing relativistic features in large-scale structure surveys -- II: Doppler magnification in an ensemble of relativistic simulations
Louis Coates, Julian Adamek, Philip Bull +2
The standard cosmological model is inherently relativistic, and yet a wide range of cosmological observations can be predicted accurately from essentially Newtonian theory. This is…
Observing relativistic features in large-scale structure surveys -- I: Multipoles of the power spectrum
Caroline Guandalin, Julian Adamek, Philip Bull +3
Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation, and…
Weak-lensing observables in relativistic N-body simulations
Francesca Lepori, Julian Adamek, Ruth Durrer +2
We present a numerical weak-lensing analysis that is fully relativistic and non-perturbative for the scalar part of the gravitational potential and first-order in the vector part,…
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…
