Probability distribution function of the aperture mass field with large deviation theory

no code implementations7 Dec 2020 Alexandre Barthelemy, Sandrine Codis, Francis Bernardeau

Furthermore we show that, with the help of a nulling procedure based on the so-called BNT transform, it is possible to build observables that depend only on a finite range of redshifts making them also independent from the small-scale modes.
