# DEMNUni: ISW, Rees-Sciama, and weak-lensing in the presence of massive neutrinos

@article{Carbone2016DEMNUniIR, title={DEMNUni: ISW, Rees-Sciama, and weak-lensing in the presence of massive neutrinos}, author={Carmelita Carbone and Margarita Petkova and Klaus Dolag}, journal={Journal of Cosmology and Astroparticle Physics}, year={2016}, volume={2016}, pages={034 - 034} }

We present, for the first time in the literature, a full reconstruction of the total (linear and non-linear) ISW/Rees-Sciama effect in the presence of massive neutrinos, together with its cross-correlations with CMB-lensing and weak-lensing signals. The present analyses make use of all-sky maps extracted via ray-tracing across the gravitational potential distribution provided by the ``Dark Energy and Massive Neutrino Universe'' (DEMNUni) project, a set of large-volume, high-resolution…
