Cosmic inflation provides a window to the highest energy densities accessible in nature, far
beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the …

We perform the first application of the wavelet scattering transform (WST) to actual galaxy
observations, through a WST analysis of the BOSS DR12 CMASS dataset. We included the …

For the last decade, several probes have pointed to a cosmological tension between the
amplitude of density fluctuations extrapolated from the cosmic microwave background within …

We use N-body simulations to study halo assembly bias (ie, the dependence of halo
clustering on properties beyond total mass) in the density and primordial non-Gaussianity …

Extracting the non-Gaussian information encoded in the higher-order clustering statistics of
the large-scale structure is key to fully realizing the potential of upcoming galaxy surveys …

The power spectrum and bispectrum of dark matter tracers are key and complementary
probes of the Universe. Next-generation surveys will deliver good measurements of the …

This paper presents the PNG-UNITSIMS suite, which includes the largest full N-body
simulation to date with local primordial non-Gaussianities (local PNG), the PNG-UNIT. The …

Primordial non-Gaussianity of the local type induces a strong scale-dependent bias on the
clustering of halos in the late-time Universe. This signature is particularly promising to …

What would a parity-violating universe look like? We present a numerical and theoretical
study of mirror asymmetries in the late universe, using a new suite of N-body simulations …

We build a field-level emulator for cosmic structure formation that is accurate in the nonlinear
regime. Our emulator consists of two convolutional neural networks trained to output the …
