The Formation Probability of Primordial Black Holes
Matteo Biagetti, Valerio De Luca, Gabriele Franciolini +2
We calculate the exact formation probability of primordial black holes generated during the collapse at horizon re-entry of large fluctuations produced during inflation, such as th…
Topological Echoes of Primordial Physics in the Universe at Large Scales
Alex Cole, Matteo Biagetti, Gary Shiu
We present a pipeline for characterizing and constraining initial conditions in cosmology via persistent homology. The cosmological observable of interest is the cosmic web of larg…
Primordial Non-Gaussianity from Biased Tracers: Likelihood Analysis of Real-Space Power Spectrum and Bispectrum
Azadeh Moradinezhad Dizgah, Matteo Biagetti, Emiliano Sefusatti +2
Upcoming galaxy redshift surveys promise to significantly improve current limits on primordial non-Gaussianity (PNG) through measurements of 2- and 3-point correlation functions in…
Primordial Gravitational Waves from Galaxy Intrinsic Alignments
Matteo Biagetti, Giorgio Orlando
Galaxy shapes have been observed to align with external tidal fields generated by the large-scale structures of the Universe. While the main source for these tidal fields is provid…
Measurement of Void Bias Using Separate Universe Simulations
Kwan Chuen Chan, Yin Li, Matteo Biagetti +1
Cosmic voids are biased tracers of the large-scale structure of the universe. Separate universe simulations (SUS) enable accurate measurements of this biasing relation by implement…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
