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…
The Persistence of Large Scale Structures I: Primordial non-Gaussianity
Matteo Biagetti, Alex Cole, Gary Shiu
We develop an analysis pipeline for characterizing the topology of large scale structure and extracting cosmological constraints based on persistent homology. Persistent homology i…
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…
