Cascading Dark Energy

The Astrophysical Journal
The standard cosmological model is in the midst of a stress test, thanks to the tension between supernova-based measurements of the Hubble constant H _0 and inferences of its values from cosmic microwave background (CMB) anisotropies.

Dark Energy and Gravity

, 2007
I review the problem of dark energy focusing on the cosmological constant as the candidate and discuss its implications for the nature of gravity. Part 1 briefly overviews the currently popular `concordance cosmology' and summarises the evidence for dark

Dark energy in the dark ages [PDF]

Astroparticle Physics, 2006
Non-negligible dark energy density at high redshifts would indicate dark energy physics distinct from a cosmological constant or ``reasonable'' canonical scalar fields. Such dark energy can be constrained tightly through investigation of the growth of structure, with limits of \la2% of total energy density at z\gg1 for many models.

Explaining Holographic Dark Energy

Galaxies, 2013
The possible holographic origin of dark energy is investigated. The main existing explanations, namely the UV/IR connection argument of Cohen et al., Thomas’ bulk holography argument, and Ng’s spacetime foam argument, are shown to be not wholly ...

Subquantum dark energy [PDF]

Physical Review D, 2004
A procedure is considered which upgrades the Lagrangian description of quantum relativistic particles to the Lagrangian of a proper field theory in the case that the Klein-Gordon wave equation is classically interpreted in terms of a relativistic sub-quantum potential.

Holographic Dark Information Energy

Entropy, 2011
Landauer’s principle and the Holographic principle are used to derive the holographic information energy contribution to the Universe. Information energy density has increased with star formation until sufficient to start accelerating the expansion of ...

Dark Matter and Dark Energy Induced by Condensates

Advances in High Energy Physics, 2016
It is shown that the vacuum condensate induced by many phenomena behaves as a perfect fluid which, under particular conditions, has zero or negative pressure.

Testing the LSST Difference Image Analysis Pipeline Using Synthetic Source Injection Analysis

The Astrophysical Journal
We evaluate the performance of the Legacy Survey of Space and Time Science Pipelines Difference Image Analysis (DIA) on simulated images. By adding synthetic sources to galaxies on images, we trace the recovery of injected synthetic sources to evaluate ...
