Dark Energy Survey reveals most accurate measurement of dark matter structure in the universe（图）
Dark Energy Survey most accurate measurement dark matter structure the universe
2017/9/4
Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof tha...
The Dark Energy Survey is now in its third year of capturing eye-popping images of the cosmos with its primary instrument, the Dark Energy Camera. Before the survey proper began in August 20...
f(T) gravity mimicking dynamical dark energy. Background and perturbation analysis
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc) High Energy Physics - Theory (hep-th)
2010/12/28
We investigate f(T) cosmology in both the background, as well as in the perturbation level, and we present the general formalism for reconstructing the equivalent one-parameter family of f(T) models f...
Induced Gravity and the Attractor Dynamics of Dark Energy/Dark Matter
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/29
Attractor solutions that give dynamical reasons for dark energy to act like the cosmological constant, or behavior close to it, are interesting possibilities to explain cosmic acceleration.
Dark Energy and QCD Ghost
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/27
It has been suggested that the dark energy that explains the observed accelerating expansion of the universe may arise due to the contribution to the vacuum energy of the QCD ghost in a time-dependent...
