35. Tomographic analysis with the weak lensing convergence one-point statistics (Castiblanco, presented by Harnois-Deraps)

05/06/2024, 14:30

The weak lensing convergence probability distribution function (PDF) has proven to contain valuable information for improving the constraints on cosmological parameters. The convergence PDF can be easily measured from simulated and observed mass maps and can be modelled with high accuracy on mildly non-linear scales. In this work we investigate the constraining power of the convergence PDF...

37. The Effective Field Theory of Large-Scale Structure and Multi-tracer (Voivodic)

05/06/2024, 15:30

We study the performance of the perturbative bias expansion when combined with the multi-tracer technique, and their impact on the extraction of cosmological parameters. We consider two populations of tracers of large-scale structure and perform a series of Markov chain Monte Carlo analysis for those two tracers separately. The constraints in ωcdm and h using multi-tracer are less biased and...

8. Going beyond redshift-space distortions with the streaming model (Dam)

05/06/2024, 16:00

There are several effects which distort the observed clustering of galaxies. By far the best known are redshift-space distortions. In this talk I will discuss another, more subtle effect - the effect of gravitational redshift on large-scale structure. The impact of this non-kinematic effect is suppressed relative to RSD in the auto-correlations and is best probed in the odd multipoles of the...
