  • Subpercent Accurate Fitting of Modified Gravity Growth 
    Denissenya, Mikhail; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2017-09-25)
    Adding to our previous method for dealing with gravitational modifications at redshiftz&3through a single parameter, we investigate treatment of lower redshift modifications to linear growth observables. We establish sub ...
  • Vacuum phase transition solves the H0 tension 
    Di Valentino, Eleonora; Linder, Eric V. (American Physical Society, 2018-02-23)
    Taking the Planck cosmic microwave background data and the more direct Hubble constant measurement data as unaffected by systematic offsets, the values of the Hubble constant $H_0$ interpreted within the $\Lambda$CDM ...
  • The Well-Tempered Cosmological Constant 
    Appleby, Stephen; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2018-05-01)
    Self tuning is one of the few methods for dynamically cancelling a large cosmological constantand yet giving an accelerating universe. Its drawback is that it tends to screen all sources of energydensity, including matter. ...
  • Will Gravitational Wave Sirens Determine the Hubble Constant? [Article] 
    Shafieloo, Arman; Keeley, Ryan E.; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2018-12-19)
    Lack of knowledge about the background expansion history of the Universe from independent observations makes it problematic to obtain a precise and accurate estimation of the Hubble constant H0 from gravitational wave ...
  • Λ is Coming: Parametrizing Freezing Fields 
    Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2018-03-21)
    We explore freezing dark energy, where the evolution of the field approaches that of a cosmological constant at late times. We propose two general, two-parameter forms to describe the class of freezing field models, in ...
