27. Building the EFT of LSS beyond the standard model (Castorina)

05/06/2024, 09:00

Any new dynamics at low-redshift must be properly included in the perturbative solutions of the matter fields and in galaxy bias. In this talk, I will give some examples of how new physics in the dark matter sector changes the structure of the perturbative kernels, introduce new counterterms in the EFT and new galaxy bias parameters.

28. Large scale structure formation in theories with scale dependent linear growth (Aviles)

05/06/2024, 09:30

In this talk, I will present recent developments in perturbation theory regarding the study of the large-scale clustering of galaxies in theories with scale-dependent linear growth, such as those involving massive neutrinos and modified gravity. The challenge in these models is that the introduced scale is incorporated into the perturbative kernels. We utilize the Lagrangian approach to...

29. New tests of dark matter and inflation with BOSS using perturbation theory (Ivanov)

31. PNG in LSS modeling and analyses (Philcox)

32. Field level bias modeling, assembly bias, and primordial non-Gaussianity (Sullivan)

05/06/2024, 12:00

Local Primordial non-Gaussianity (PNG) will be a primary science target for galaxy clustering analyses using SPHEREx, DESI, and Euclid data. Maximally extracting information about the amplitude of PNG (f_{NL}) will require knowledge of galaxy formation physics, which can robustly be embedded in the values of bias parameters in large-scale perturbative models. I will describe several...
