Galaxies are subject to intrinsic alignments, which correspond to the correlations between their 3D shapes and orientations and the underlying tidal field of dark matter across the large-scale structure of the Universe. This intrinsic galaxy alignment is traditionally measured with the two-point galaxy-density correlation function projected in the sky plane. However, the projection of 3D...
Cross-correlations between the thermal Sunyaev–Zel’dovich (tSZ) effect and tracers of large-scale structure provide a powerful probe of both astrophysics and cosmology. In this talk, I will present results on the cross-correlation of the tSZ signal with weak gravitational lensing and galaxy clustering in the context of the Euclid mission. These measurements allow us to study the distribution...
