Cosmology inference with perturbative forward modeling at the field level: a comparison with joint power spectrum and bispectrum analyses
Kazuyuki Akitsu, Marko Simonović, Shi-Fan Chen +2
We extend field-level inference to jointly constrain the cosmological parameters , in both real and redshift space. Our analyses are based on mock data gener…

Equivalence of the field-level inference and conventional analyses on large scales
Francesco Spezzati, Marco Marinucci, Marko Simonović
We study a simple setup with dark matter halos in real space, with the amplitude of the linear density field as the only free cosmological parameter. We show that Eulerian pert…
