Testing Primordial Black Holes as Dark Matter through LISA
N. Bartolo, V. De Luca, G. Franciolini +3
The idea that primordial black holes (PBHs) can comprise most of the dark matter of the universe has recently reacquired a lot of momentum. Observational constraints, however, rule…

Measuring chiral gravitational waves in Chern-Simons gravity with CMB bispectra
Nicola Bartolo, Giorgio Orlando, Maresuke Shiraishi
Chern-Simons gravity coupled to the scalar sector through a generic coupling function can be tested at the very high energies of the inflationary period. In 1706.04627, we c…

Isotropic non-Gaussian -like toy models that reproduce the cosmic microwave background anomalies
F. K. Hansen, T. Trombetti, N. Bartolo +4
Based on recent observations of the cosmic microwave background (CMB), claims of statistical anomalies in the properties of the CMB fluctuations have been made. Although the statis…
