CMB anomalies and the effects of local features of the inflaton potential
Alexander Gallego Cadavid, Antonio Enea Romano, Stefano Gariazzo
Recent analysis of the WMAP and Planck data have shown the presence of a dip and a bump in the spectrum of primordial perturbations at the scales Mpc and $k=0.00…
Newton gauge cosmological perturbations for static spherically symmetric modifications of the de Sitter metric
Camilo Santa Velez, Antonio Enea Romano
Static coordinates can be convenient to solve the vacuum Einstein's equations in presence of spherical symmetry, but for cosmological applications comoving coordinates are more sui…
Hubble trouble or Hubble bubble?
Antonio Enea Romano
The recent analysis of low-redshift supernovae (SN) has increased the apparent tension between the value of estimated from low and high redshift observations such as the cosm…
General background conditions for K-bounce and adiabaticity
Antonio Enea Romano
We study the background conditions for a bounce uniquely driven by a single scalar field model with a generalized kinetic term , without any additional matter field. At the b…
Global adiabaticity and non-Gaussianity consistency condition
Antonio Enea Romano, Sander Mooij, Misao Sasaki
In the context of single-field inflation, the conservation of the curvature perturbation on comoving slices, , on super-horizon scales is one of the assumptions necessary to…
