22 Jun 2022 | | Abstract: | We present cosmological constraints from the analysis of two-point
correlation functions between galaxy positions and galaxy lensing measured in
Dark Energy Survey (DES) Year 3 data and measurements of cosmic microwave
background (CMB) lensing from the South Pole Telescope (SPT) and Planck. When
jointly analyzing the DES-only two-point functions and the DES
cross-correlations with SPT+Planck CMB lensing, we find $Omega_{
m m} =
0.344pm 0.030$ and $S_8 equiv sigma_8 (Omega_{
m m}/0.3)^{0.5} = 0.773pm
0.016$, assuming $Lambda$CDM. When additionally combining with measurements of
the CMB lensing autospectrum, we find $Omega_{
m m} =
0.306^{+0.018}_{-0.021}$ and $S_8 = 0.792pm 0.012$. The high signal-to-noise
of the CMB lensing cross-correlations enables several powerful consistency
tests of these results, including comparisons with constraints derived from
cross-correlations only, and comparisons designed to test the robustness of the
galaxy lensing and clustering measurements from DES. Applying these tests to
our measurements, we find no evidence of significant biases in the baseline
cosmological constraints from the DES-only analyses or from the joint analyses
with CMB lensing cross-correlations. However, the CMB lensing
cross-correlations suggest possible problems with the correlation function
measurements using alternative lens galaxy samples, in particular the redMaGiC
galaxies and high-redshift MagLim galaxies, consistent with the findings of
previous studies. We use the CMB lensing cross-correlations to identify
directions for further investigating these problems. | | Source: | arXiv, 2206.10824 | | Services: | Forum | Review | PDF | Favorites | |
