Constraining graviton non-Gaussianity through the CMB bispectra
Valerio De Luca, Gabriele Franciolini, Alex Kehagias +2
Tensor non-Gaussianities are a key ingredient to test the symmetries and the presence of higher spin fields during the inflationary epoch. Indeed, the shape of the three point corr…
Gravitational Wave Anisotropies from Primordial Black Holes
N. Bartolo, D. Bertacca, V. De Luca +6
An observable stochastic background of gravitational waves is generated whenever primordial black holes are created in the early universe thanks to a small-scale enhancement of the…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Cosmological Shapes of Higher-Spin Gravity
D. Anninos, V. De Luca, G. Franciolini +2
We explore non-Gaussian features of a massless spin-two field in the Vasiliev theory of higher-spin gravity. The theory contains an infinite tower of interacting gauge fields with…
