Phenomenology of Large Scale Structure in scalar-tensor theories: joint prior covariance of , and in Horndeski
Juan Espejo, Simone Peirone, Marco Raveri +3
Ongoing and upcoming cosmological surveys will significantly improve our ability to probe the equation of state of dark energy, , and the phenomenology of Large Scale S…
Evolution of dark energy reconstructed from the latest observations
Yuting Wang, Levon Pogosian, Gong-Bo Zhao +1
We reconstruct evolution of the dark energy (DE) density using a nonparametric Bayesian approach from a combination of latest observational data. We caution against parameterizing…
Large-scale structure phenomenology of viable Horndeski theories
Simone Peirone, Kazuya Koyama, Levon Pogosian +2
Phenomenological functions and , also known as and , are commonly used to parameterize modifications of the growth of large-scale structu…
Searching for Primordial Magnetic Fields with CMB B-modes
Levon Pogosian, Alex Zucca
Was the primordial universe magnetized? The answer to this question would help explain the origin of micro-Gauss strength magnetic fields observed in galaxies. It is also of fundam…
