We introduce here a cross-correlation term between CMB lensing and galaxy intrinsic alignment, noted hereby as $\phi I$. This effect acts as a contaminant to the cross-correlation between CMB lensing and galaxy lensing. The latter…

Lensing reconstruction maps from the cosmic microwave background (CMB) provide direct observations of the matter distribution of the universe without the use of a biased tracer. Such maps, however, constitute projected observables along the…

Observational cosmology has indeed made very rapid progress in recent years. The ability to quantify the universe has largely improved due to observational constraints coming from structure formation. The transition to precision cosmology…
