Slicing the vacuum: New accelerating mirror solutions of the dynamical Casimir effect

Good, Michael R.R.; Linder, Eric V. (American Physical Society, 2017-12-22)

Radiation from accelerating mirrors in a Minkowski spacetime provides insights into the nature of horizons, black holes, and entanglement entropy. We introduce new, simple, symmetric and analytic moving mirror solutions ...
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 ...
Twin LIGO/Virgo Detections of a Viable Gravitationally-Lensed Black Hole Merger

Broadhurst, Tom; Smoot, George F.; Diego, Jose M. (NURIS; Energetic Cosmos Laboratory, 2019-01-10)

We identify a binary black hole (BBH) merger that appears to be multiply lensed by an intervening galaxy. The LIGO/Virgo events GW170809 and GW170814 have indistinguishable waveforms separated by 5 days, and overlap on the ...
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 ...
Witnessing the reionization history using Cosmic Microwave Background observation from Planck

Hazra, Dhiraj Kumar; Smoot, George F (NURIS; Energetic Cosmos Laboratory, 2017-12-11)

We constrain the history of reionization using the data from Planck 2015 Cosmic Microwave Background (CMB) temperature and polarization anisotropy observations. We also use prior constraints on the reionization history at ...
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 ...
