SkyPy: A package for modelling the Universe
Adam Amara, Lucia F. de la Bella, Simon Birrer +18
SkyPy is an open-source Python package for simulating the astrophysical sky. It comprises a library of physical and empirical models across a range of observables and a command-lin…
lenstronomy II: A gravitational lensing software ecosystem
Simon Birrer, Anowar J. Shajib, Daniel Gilman +18
lenstronomy is an Astropy-affiliated Python package for gravitational lensing simulations and analyses. lenstronomy was introduced by Birrer and Amara (2018) and is based on the li…
The unequal-time matter power spectrum: impact on weak lensing observables
Lucia F. de la Bella, Nicolas Tessore, Sarah Bridle
We investigate the impact of a common approximation on weak lensing power spectra: the use of single-epoch matter power spectra in integrals over redshift. We disentangle this from…
Spin characterisation of systematics in CMB surveys -- a comprehensive formalism
Nialh McCallum, Daniel B. Thomas, Michael L. Brown +1
The CMB -mode polarisation signal -- both the primordial gravitational wave signature and the signal sourced by lensing -- is subject to many contaminants from systematic effect…
Reconstructing the Gravitational Lensing Potential from the Lyman- Forest
R. Benton Metcalf, Nicolas Tessore, Rupert A. C. Croft
We demonstrate a method for reconstructing the weak lensing potential from the Lyman- forest data. We derive an optimal estimator for the lensing potential on the sky based on t…
The Spectral Representation of Homogeneous Spin-Weighted Random Fields on the Sphere
Nicolas Tessore
This is a direct computation of the spectral representation of homogeneous spin-weighted spherical random fields with arbitrary integer spin. It generalises known results from Cosm…
