Data-Driven Discovery of a Simple Phantom-Crossing Dark Energy Parametrization
Giulia Borghetto, Ameek Malhotra, Simran Arora +4
We develop a data-driven reconstruction programme for the dark-energy equation of state within VCDM, a minimally modified gravity framework in which both background and linear pert…
Perturbations in string cosmology from double field theory
Stephen Angus, Shinji Mukohyama
The low-energy limit of string theory contains additional gravitational degrees of freedom, a skew-symmetric tensor -field and a scalar dilaton, that are not present in general…
Bispectrum from inflation/bouncing Universe in VCDM
Alexander Ganz, Paul Martens, Shinji Mukohyama +1
We discuss the non-linear interactions within the VCDM model, a type II minimally modified gravity model with the same number of degrees of freedom as in General Relativity but not…
Are theories really relevant to cosmology?
Osmin Lacombe, Shinji Mukohyama, Josef Seitz
We examine theories that directly couple the curvature or with the matter sector in the action, in addition to the universal coupling. We argue…
Revisiting the stochastic QCD axion window: departure from equilibrium during inflation
Vadim Briaud, Kenji Kadota, Shinji Mukohyama +2
If dark matter is made of QCD axions, its abundance is determined by the vacuum expectation value acquired by the axion field during inflation. The axion is usually assumed to foll…
