Parity-odd Four-Point Correlation Function from DESI Data Release 1 Luminous Red Galaxy Sample
J. Hou, R. N. Cahn, J. Aguilar +33
The parity-odd four-point function provides a unique probe of fundamental symmetries and potential new physics in the large-scale structure of the Universe. We present measurements…

Study of the Connected Four-Point Correlation Function of Galaxies from DESI Data Release 1 Luminous Red Galaxy Sample
J. Hou, R. N. Cahn, J. Aguilar +43
We present a measurement of the non-Gaussian four-point correlation function (4PCF) from the DESI DR1 Luminous Red Galaxy (LRG) sample. For the gravitationally induced parity-even…

Mitigation of DESI fiber assignment incompleteness effect on two-point clustering with small angular scale truncated estimators
M. Pinon, A. de Mattia, P. McDonald +50
We present a method to mitigate the effects of fiber assignment incompleteness in two-point power spectrum and correlation function measurements from galaxy spectroscopic surveys,…
