Effective speed of gravitational waves
Antonio Enea Romano
We derive an effective equation and action for the propagation of gravitational waves (GW), encoding the effects of interaction and self-interaction in a time, frequency and polari…
Reconstructing homospectral inflationary potentials
Alexander Gallego Cadavid, Antonio Enea Romano, Andrew R. Liddle
Purely geometrical arguments show that there exist classes of homospectral inflationary cosmologies, i.e. different expansion histories producing the same spectrum of comoving curv…
tension or overestimation?
Brayan Yamid Del Valle Mazo, Antonio Enea Romano, Maryi Alejandra Carvajal Quintero
There is a strong discrepancy between the value of the Hubble parameter obtained from large scale observations such as the Planck mission, and the small scale value …
Deep learning reconstruction of the large scale structure of the Universe from luminosity distance observations
Cristhian García, Camilo Santa, Antonio Enea Romano
Supernovae Ia (SNe) can provide a unique window on the large scale structure (LSS) of the Universe at redshifts where few other observations are available, by solving the inversion…
Effects of the shape of curvature peaks on the size of primordial black holes
Albert Escrivà, Antonio Enea Romano
We simulate numerically the formation of spherically symmetric primordial black holes (PBHs) seeded by different families of primordial curvature perturbations profiles on a Friedm…
Sound speed induced production of primordial black holes
Antonio Enea Romano
We study different mechanisms by which the speed of primordial curvature perturbations can produce an enhancement of the curvature spectrum, which could lead to the production of p…
