DETERMINING MODEL-INDEPENDENT H0 AND CONSISTENCY TESTS

Liao, Kai; Shafieloo, Arman; Keeley, Ryan E.; Linder, Eric V. (arxiv, 2020)

We determine the Hubble constant H0 precisely (2.3% uncertainty) in a manner independent of cosmological model through Gaussian process regression, using strong lensing and supernova data. Strong gravitational lensing ...
EXPLORING EARLY AND LATE COSMOLOGY WITH NEXT GENERATION SURVEYS

Brando, Guilherme; Linder, Eric V. (PHYSICAL REVIEW D, 2020)

Perturbations from inflation evolve into large scale structure of the late universe, and encode abundant cosmic structure formation physics. We allow freedom in the primordial power spectrum, rather than assuming a power ...
