Various pulsar timing array (PTA) experiments (NANOGrav, EPTA, PPTA, CPTA, including
data from InPTA) very recently reported evidence for excess red common-spectrum signals …

We present a framework for self-consistent cosmological analyses of the full-shape
anisotropic bispectrum, including the quadrupole (ℓ= 2) and hexadecapole (ℓ= 4) moments …

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 study the cosmological information content of the redshift-space galaxy bispectrum
monopole at one-loop order in perturbation theory. We incorporate all effects necessary for …

Could new physics break the mirror symmetry of the Universe? Utilizing recent
measurements of the parity-odd four-point correlation function of BOSS galaxies, we probe …

I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

The scale-dependent bias effect on the galaxy power spectrum is a very promising probe of
the local primordial non-Gaussianity (PNG) parameter f NL, but the amplitude of the effect is …

We revisit cosmological constraints on the sum of the neutrino masses Σ m ν from a
combination of full-shape BOSS galaxy clustering [P (k)] data and measurements of the …

We develop a pipeline to set new constraints on scale-independent modified gravity, from
the galaxy power spectrum in redshift space of BOSS DR12. The latter is modelled using the …

Deviations from the blackbody spectral energy distribution of the cosmic microwave
background (CMB) are a precise probe of physical processes active both in the early …
