Discreteness Effects in the Post-Reconstruction Galaxy Power Spectrum
Naonori Sugiyama
Recent studies have increasingly recognized the value of analyzing the post-reconstruction galaxy power spectrum for investigations into redshift space distortion (RSD) effects. In…

Developing a Theoretical Model for the Resummation of Infrared Effects in the Pre- and Post-Reconstruction Galaxy Bispectra (https://youtu.be/bHdlIi3jQ4A)
Naonori Sugiyama
While substantial progress has been made in studying the pre-reconstruction galaxy bispectrum, investigations of the post-reconstruction bispectrum are still in nascent stages. In…

Developing a Theoretical Model for the Resummation of Infrared Effects in the Post-Reconstruction Power Spectrum (an explanatory video is available in the comments section)
Naonori Sugiyama
Since galaxy distribution reconstruction effectively reduces non-Gaussian terms in the power spectrum covariance matrix, it has attracted interest not only for Baryon Acoustic Osci…
