We provide a new fitting formula of the matter bispectrum in the nonlinear regime calibrated
by high-resolution cosmological N-body simulations of 41 cold dark matter (wCDM, w …

The combination and cross-correlation of the upcoming Euclid data with cosmic microwave
background (CMB) measurements is a source of great expectation since it will provide the …

We report a new test of modified gravity theories using the large-scale structure of the
Universe. This paper is the first attempt to (1) apply a joint analysis of the anisotropic …

We investigate the prospects for using the weak lensing bispectrum alongside the power
spectrum to control systematic uncertainties in a Euclid-like survey. Three systematic effects …

We present the integrated three-point shear correlation function i ζ±–a higher order statistic
of the cosmic shear field–which can be directly estimated in wide-area weak lensing surveys …

The power spectrum of weak lensing fluctuations has a non-Gaussian distribution due to its
quadratic nature. On small scales the central limit theorem acts to Gaussianize this …

Producing thousands of simulations of the dark matter distribution in the Universe with
increasing precision is a challenging but critical task to facilitate the exploitation of current …

We present a first measurement of the galaxy-galaxy-CMB lensing bispectrum. The signal is
detected at $26\sigma $ and $22\sigma $ significance using two samples from the unWISE …

The significant increase in precision that will be achieved by Stage IV cosmic shear surveys
means that several currently used theoretical approximations may cease to be valid. An …

We introduce and study a new scheme to construct relativistic observables from
postprocessing light cone data. This construction is based on a novel approach, lc-metric …
