An analytic approximation to the covariance between pre- and post-reconstruction galaxy two-point statistics
M. Maus, A. Baleato Lizancos, M. White +2
We present a simple analytic approximation for the covariance between pre-reconstruction galaxy power spectrum measurements and post-reconstruction two-point correlation functions.…
Field-Level Inference from Galaxies: BAO Reconstruction
Adrian E. Bayer, Liam Parker, David Valcin +3
Baryon acoustic oscillations (BAO) underpin the key cosmological results from modern spectroscopic galaxy surveys, but nonlinear gravitational evolution limits the precision achiev…
Cosmology inference with perturbative forward modeling at the field level: a comparison with joint power spectrum and bispectrum analyses
Kazuyuki Akitsu, Marko SimonoviÄ, 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 gene…
It's All : Curvature in Light of BAO from DESI DR2
Shi-Fan Chen, Matias Zaldarriaga
Recent measurements of baryon acoustic oscillations (BAO) from the Dark Energy Spectroscopic Instrument (DESI) show hints of tension with data from the cosmic microwave background…
