Physics Letters B, 2003 Velocity-dependent interactions in a fundamental-string dominated universe lead quite naturally, with reasonable assumptions on initial conditions, to an accelerating expanding universe without assuming the existence of a cosmological constant. This result also holds generically for a universe dominated by moving extremal black holes, owing to a ...

Why we need to see the dark matter to understand the dark energy [PDF]
J.Phys.Conf.Ser.110:062014,2008, 2007 The cosmological concordance model contains two separate constituents which interact only gravitationally with themselves and everything else, the dark matter and the dark energy. In the standard dark energy models, the dark matter makes up some 20% of the total energy budget today, while the dark energy is responsible for about 75%.

Holographic Dark Information Energy: Predicted Dark Energy Measurement
Entropy, 2013 Several models have been proposed to explain the dark energy that is causing universe expansion to accelerate. Here the acceleration predicted by the Holographic Dark Information Energy (HDIE) model is compared to the acceleration that would be produced ...

The Astronomical Journal, 2023 We present a study of the potential for convolutional neural networks (CNNs) to enable separation of astrophysical transients from image artifacts, a task known as “real–bogus” classification, without requiring a template-subtracted (or difference) image,

International Journal of Modern Physics D, 2006 Recent large-scale peculiar velocity surveys suggest that large matter volumes could be moving with appreciable velocity with respect to the CMB rest frame. If confirmed, such results could conflict with the Cosmological Principle according to which the matter and CMB rest frames should converge on very large scales.

Testing dark energy after pre-recombination early dark energy
Physics Letters B, 2022 In the studies on pre-recombination early dark energy (EDE), the evolution of Universe after recombination is usually regarded as ΛCDM-like, which corresponds that the equation of state of dark energy responsible for current accelerated expansion is w=−1.
