Signatures of primordial black holes as seeds of supermassive black holes
José Luis Bernal, Alvise Raccanelli, Licia Verde +1
It is broadly accepted that Supermassive Black Holes (SMBHs) are located in the centers of most massive galaxies, although there is still no convincing scenario for the origin of t…
Peering beyond the horizon with standard sirens and redshift drift
Raul Jimenez, Alvise Raccanelli, Licia Verde +1
An interesting test on the nature of the Universe is to measure the global spatial curvature of the metric in a model independent way, at a level of , or, if possibl…
Cosmological implications of Primordial Black Holes
José Luis Bernal, Nicola Bellomo, Alvise Raccanelli +1
The possibility that a relevant fraction of the dark matter might be comprised of Primordial Black Holes (PBHs) has been seriously reconsidered after LIGO's detection of a $\sim 30…
Primordial Black Holes as Dark Matter: Converting Constraints from Monochromatic to Extended Mass Distributions
Nicola Bellomo, José Luis Bernal, Alvise Raccanelli +1
The model in which Primordial Black Holes (PBHs) constitute a non-negligible fraction of the dark matter has (re)gained popularity after the first detections of binary black hole m…
Effects of primordial black holes quantum gravity decay on galaxy clustering
Alvise Raccanelli, Francesca Vidotto, Licia Verde
It has been recently suggested that small mass black holes (BHs) may become unstable due to quantum-gravitational effects and eventually decay, producing radiation, on a timescale…
Relativistic wide-angle galaxy bispectrum on the light-cone
Daniele Bertacca, Alvise Raccanelli, Nicola Bartolo +3
Given the important role that the galaxy bispectrum has recently acquired in cosmology and the scale and precision of forthcoming galaxy clustering observations, it is timely to de…
Biases from neutrino bias: to worry or not to worry?
Alvise Raccanelli, Licia Verde, Francisco Villaescusa-Navarro
The relation between the halo field and the matter fluctuations (halo bias), in the presence of massive neutrinos depends on the total neutrino mass, massive neutrinos introduce an…
Cosmological perturbation effects on gravitational-wave luminosity distance estimates
Daniele Bertacca, Alvise Raccanelli, Nicola Bartolo +1
Waveforms of gravitational waves provide information about a variety of parameters for the binary system merging. However, standard calculations have been performed assuming a FLRW…
