Some RayGal images

RayGal narrow inteermediate lightcone: comoving matter overdensity (no relativistic effect)
RayGal narrow inteermediate lightcone: Doppler contribution (i.e. standard redshift space distortions including wide angle effect plus transverse Doppler) to the apparent matter overdensity
RayGal narrow inteermediate lightcone: Gravitational redshift contribution (i.e. from the gravitational potential) to the apparent matter overdensity
RayGal narrow inteermediate lightcone: Weak lensing contribution (i.e. from light deflection) to the apparent matter overdensity
RayGal narrow inteermediate lightcone: Integrated Sachs-Wolfe & Rees-Sciama contribution (i.e. from the time-varying gravitational potential) to the apparent matter overdensity
RayGal narrow inteermediate lightcone: apparent matter overdensity at cosmic scales with all general relativistic effects for light propagation at first order in the weak-field approximation (Doppler& Transverse Doppler, gravitational redshift, weak-lensing, Inteegrated-Sachs-Wolfe & Rees-Sciama). See Rasera, Breton et al., 2021 for more details.

Importance of Adaptive Mesh Refinement (AMR) for the ray-tracing: Convergence power spectrum (multiplied by l (l+1)/2pi) from RayGal at z=0.45. In blue the ray-tracing with Magrathea-pathfinder is performed without AMR and in red with AMR. In black, analytical predictions (Breton & Reverdy, 2021, in prep).
