LHC Lifetime Frontier and Visible Decay Searches in Composite Asymmetric Dark Matter Models [PDF]
, 2021 The LHC lifetime frontier will probe dark sector in near future, and the visible decay searches at fixed-target experiments have been exploring dark sector. Composite asymmetric dark matter with dark photon portal is a promising framework explaining the coincidence problem between dark matter and visible matter.

Metadetection Weak Lensing for the Vera C. Rubin Observatory
The Open Journal of Astrophysics, 2023 Forthcoming astronomical imaging surveys will use weak gravitational lensing shear as a primary probe to study dark energy, with accuracy requirements at the 0.1% level.

Unifying dark matter, dark energy and inflation with a fuzzy dark fluid [PDF]
, 2020 Scalar fields appear in many cosmological models, in particular in order to provide explanations for dark energy and inflation, but also to emulate dark matter. In this paper, we show that it is possible for a scalar field to replace simultaneously dark matter, dark energy and inflation by assuming the existence of a non-minimal coupling to gravity, a ...

, 2023 I have been working on the fundamental laws of physics for a long time. During this time, I realized that gravity does not work like Newtonian and this misleads us into Dark Matter. The relationship between distance and gravitational force varies with distance.

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.
