Angular bispectrum of matter number counts in cosmic structures
Thomas Montandon, Enea Di Dio, Cornelius Rampf +1
The bispectrum of galaxy number counts is a key probe of large-scale structure, offering insights into the initial conditions of the Universe, the nature of gravity, and cosmologic…

Isocurvature modes: joint analysis of the CMB power spectrum and bispectrum
Thomas Montandon, Guillaume Patanchon, Bartjan van Tent
We perform a joint analysis of the power spectrum and the bispectrum of the CMB temperature and polarization anisotropies to improve the constraints on isocurvature modes. We const…
