We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic
microwave background (CMB) anisotropy measurements. The results are fully consistent …

A bstract Scattering amplitudes at weak coupling are highly constrained by Lorentz
invariance, locality and unitarity, and depend on model details only through coupling …

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 …

We analyse the Planck full-mission cosmic microwave background (CMB) temperature and
E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We …

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 …

A bstract Cosmological correlation functions contain valuable information about the
primordial Universe, with possible signatures of new massive particles at very high energies …

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 …

The understanding of the primordial mechanism that seeded the cosmic structures we
observe today in the sky is one of the major goals in cosmology. The leading paradigm for …

Massive particles produced during inflation leave specific signatures in soft limits of
correlation functions of primordial fluctuations. When the Goldstone boson of broken time …

A bstract Massive spinning particles acquire helicity-dependent chemical potentials during
the inflation from axion-type couplings. Such spinning fields can mediate sizable inflaton …
