We present cosmological constraints from the sample of Type Ia supernovae (SNe Ia) discovered and measured during the full 5 yr of the Dark Energy Survey (DES) SN program.

Recent observational advances have considerably improved the cosmological tests, adding to the lines of evidence, and showing that some issues under discussion just a few years ago may now be considered resolved or irrelevant. Other issues remain, however, and await resolution before the great program of testing the relativistic Friedmann–Lemaître ...

Cosmological tests for a linear coasting cosmology [PDF]
A strictly linear evolution of the scale factor is a characteristic feature in several classes of alternative gravity theories. In this article we investigate the overall viability of an open linear coasting cosmological model. We report that this model is consistent with gravitational lensing statistics (within $1 $) and accomodates old high-redshift

Cosmology with the Square Kilometre Array by SKA-Japan
In the past several decades, the standard cosmological model has been established and its parameters have been measured to a high precision, while there are still many of the fundamental questions in cosmology; such as the physics in the very early ...

Testing general relativity in cosmology [PDF]
We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy ...

Indigenous Shamanic Worldviews as Dialogical Eco-Cosmology
This article deals with indigenous shamanic worldviews and indigenous knowledge as dialogical eco-cosmology. It shows the relevance of eco-cosmology as local indigenous ecological and spiritual knowledge in the context of global biodiversity and ...

Supersymmetry and cosmology [PDF]
Cosmology now provides unambiguous, quantitative evidence for new particle physics. I discuss the implications of cosmology for supersymmetry and vice versa. Topics include: motivations for supersymmetry; supersymmetry breaking; dark energy; freeze out and WIMPs; neutralino dark matter; cosmologically preferred regions of minimal supergravity; direct ...

Toward a Halo Mass Function for Precision Cosmology: The Limits of Universality [PDF]
We measure the mass function of dark matter halos in a large set of collisionless cosmological simulations of flat ΛCDM cosmology and investigate its evolution at z≲ 2.

Stop Co-Annihilation in the Minimal Supersymmetric Standard Model Revisited [PDF]
We re-examine the stop co-annihilation scenario of the Minimal Supersymmetric Standard Model, wherein a bino-like lightest supersymmetric particle has a thermal relic density set by co-annihilations with a scalar partner of the top quark in the early ...
