We present a measurement of the cross-correlation between |
|
the MAGLIM galaxies selected from the Dark Energy Survey |
|
(DES) first three years of observations (Y3) and cosmic |
|
microwave background (CMB) lensing from the Atacama |
|
Cosmology Telescope (ACT) Data Release 4 (DR4), |
|
reconstructed over 436 deg2 of the sky. Our galaxy |
|
sample, which covers 4143 deg2, is divided into six |
|
redshift bins spanning the redshift range of 0.208 8( |
|
m/0.3)0.5 = 0.75+0.04-0.05. In addition, we constrain the |
|
linear growth of cosmic structure as a function of |
|
redshift. Our results are consistent with recent DES Y3 |
|
analyses and suggest a preference for a lower S8 compared |
|
to results from measurements of CMB anisotropies by the |
|
Planck satellite, although at a mild level ( |
