Validation of the Hybrid Bias Expansion model for the galaxy bispectrum
Marcos Pellejero Ibáñez, Marcos Pellejero Ibáñez, Raul E. Angulo +10
The Hybrid Bias Expansion model (also known as Hybrid Effective Field Theory, HEFT) provides a promising way to extend the range of validity of perturbative large-scale structure m…
Perturbative Likelihoods for Large-Scale Structure of the Universe
Rodrigo Voivodic
This work presents a formalism for deriving likelihoods of the cosmological density field directly from first principles within Perturbation Theory (PT). By assuming a perturbative…
Probabilistic Lagrangian bias estimators and the cumulant bias expansion
Jens Stücker, Marcos Pellejero-Ibáñez, Raul E. Angulo +2
The spatial distribution of galaxies is a highly complex phenomenon currently impossible to predict deterministically. However, by using a statistical relation, it…
Gaussian Lagrangian Galaxy Bias
Jens Stücker, Marcos Pellejero-Ibáñez, Rodrigo Voivodic +1
Understanding -- that is the statistical relation between matter and galaxies -- is of key importance for extracting cosmological information from galaxy sur…
