MGLenS: Modified gravity weak lensing simulations for emulation-based cosmological inference
Joachim Harnois-Déraps, Cesar Hernandez-Aguayo, Carolina Cuesta-Lazaro +4
We present MGLenS, a large series of modified gravity lensing simulations tailored for cosmic shear data analyses and forecasts in which cosmological and modified gravity parameter…
Proca-stinated Cosmology II: Matter, Halo, and Lensing Statistics in the vector Galileon
Christoph Becker, Alexander Eggemeier, Christopher T. Davies +1
The generalised Proca (GP) theory is a modified gravity model in which the acceleration of the cosmic expansion rate can be explained by self interactions of a cosmological vector…
Constraining cosmology with weak lensing voids
Christopher T. Davies, Marius Cautun, Benjamin Giblin +3
Upcoming surveys such as \LSST{} and \Euclid{} will significantly improve the power of weak lensing as a cosmological probe. To maximise the information that can be extracted from…
Optimal void finders in weak lensing maps
Christopher T. Davies, Enrique Paillas, Marius Cautun +1
Cosmic voids are a key component of the large-scale structure that contain a plethora of cosmological information. Typically, voids are identified from the underlying galaxy distri…
The Accuracy of Weak Lensing Simulations
Stefan Hilbert, Alexandre Barreira, Giulio Fabbian +9
We investigate the accuracy of weak lensing simulations by comparing the results of five independently developed lensing simulation codes run on the same input -body simulation.…
Cosmological test of gravity using weak lensing voids
Christopher T. Davies, Marius Cautun, Baojiu Li
Modifications to General Relativity (GR) often incorporate screening mechanisms in order to remain compatible with existing tests of gravity. The screening is less efficient in und…
