Born-corrections to weak lensing of the cosmic microwave background temperature and polarisation anisotropies
Steffen Hagstotz, Björn Malte Schäfer, Philipp M. Merkel
Many weak lensing calculations make use of the Born approximation where the light ray is approximated by a straight path. We examine the effect of Born-corrections for lensing of t…

A theoretical estimate of intrinsic ellipticity bispectra induced by angular momenta alignments
Philipp M. Merkel, Bjoern Malte Schaefer
Intrinsically aligned galaxy shapes are one of the most important systematics in cosmic shear measurements. So far theoretical studies of intrinsic alignments almost exclusively fo…
