Fast Forward Modelling of Galaxy Spatial and Statistical Distributions
Pascale Berner, Alexandre Refregier, Beatrice Moser +3
A forward modelling approach provides simple, fast and realistic simulations of galaxy surveys, without a complex underlying model. For this purpose, galaxy clustering needs to be…
pt combined probes: pipeline, neutrino mass, and data compression
Alexander Reeves, Andrina Nicola, Alexandre Refregier +2
With the rapid advance of wide-field surveys it is increasingly important to perform combined cosmological probe analyses. We present a new pipeline for simulation-based multi-prob…
Early Structure Formation from Cosmic String Loops in Light of Early JWST Observations
Hao Jiao, Robert Brandenberger, Alexandre Refregier
Cosmic strings, if they exist, source nonlinear and non-Gaussian perturbations all the way back to the time of equal matter and radiation (and earlier). Here, we compute the mass f…
