Cosmological forecasts with the clustering of weak lensing peaks
Christopher T. Davies, Marius Cautun, Benjamin Giblin +3
Maximising the information that can be extracted from weak lensing measurements is a key goal for upcoming surveys such as LSST and Euclid. This is typically achieved through stati…
FORGE -- the f(R) gravity cosmic emulator project I: Introduction and matter power spectrum emulator
Christian Arnold, Baojiu Li, Benjamin Giblin +2
We present a large suite of cosmological simulations, the FORGE (F-of-R Gravity Emulator) simulation suite, which is designed to build accurate emulators for cosmological observabl…
Looking for a twist: probing the cosmological gravitomagnetic effect via weak lensing-kSZ cross correlations
Cristian Barrera-Hinojosa, Baojiu Li, Yan-Chuan Cai
General relativity predicts that the rotational momentum flux of matter twists the spacetime via a vector gravitomagnetic (frame-dragging) field, which remains undetected in cosmol…
Stacked CMB lensing and ISW signals around superstructures in the DESI Legacy Survey
Qianjun Hang, Shadab Alam, Yan-Chuan Cai +1
The imprints of large-scale structures on the Cosmic Microwave Background can be studied via the CMB lensing and Integrated Sachs-Wolfe (ISW) signals. In particular, the stacked IS…
Redshift-space distortions with split densities
Enrique Paillas, Yan-Chuan Cai, Nelson Padilla +1
Accurate modelling of redshift-space distortions (RSD) is challenging in the non-linear regime for two-point statistics e.g. the two-point correlation function (2PCF). We take a di…
