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…
Enhancing cosmic shear with the multi-scale lensing PDF
Benjamin Giblin, Yan-Chuan Cai, Joachim Harnois-Déraps
We quantify the cosmological constraining power of the `lensing PDF' - the one-point probability density of weak lensing convergence maps - by modelling this statistic numerically…
Dynamics of ultrarelativistic charged particles with strong radiation reaction. I. Aristotelian equilibrium state
Yangyang Cai, Samuel E. Gralla, Vasileios Paschalidis
Previous studies from the astrophysics and laser physics communities have identified an interesting phenomenon wherein ultrarelativistic charged particles experiencing strong radia…
Measuring cosmic filament spin with the kinetic Sunyaev-Zel'dovich effect
Yi Zheng, Yan-Chuan Cai, Weishan Zhu +3
The spin of intergalactic filaments has been predicted from simulations, and supported by tentative evidence from redshift-space filament shapes in a galaxy redshift survey: genera…
Constraining νΛCDM with density-split clustering
Enrique Paillas, Carolina Cuesta-Lazaro, Pauline Zarrouk +6
The dependence of galaxy clustering on local density provides an effective method for extracting non-Gaussian information from galaxy surveys. The two-point correlation function (2…
Galaxy and Mass Assembly (GAMA): Probing galaxy-group correlations in redshift space with the halo streaming model
Qianjun Hang, John A. Peacock, Shadab Alam +6
We have studied the galaxy-group cross-correlations in redshift space for the Galaxy And Mass Assembly (GAMA) Survey. We use a set of mock GAMA galaxy and group catalogues to devel…
