A Test of the Cosmological Principle with Quasars [PDF]
, 2020 We study the large-scale anisotropy of the universe by measuring the dipole in the angular distribution of a flux-limited, all-sky sample of 1.36 million quasars observed by the Wide-field Infrared Survey Explorer (WISE).

Ultralight scalars as cosmological dark matter [PDF]
, 2016 Many aspects of the large-scale structure of the Universe can be described successfully using cosmological models in which 27±1% of the critical mass-energy density consists of cold dark matter (CDM).

Lemaître Class Dark Energy Model for Relaxing Cosmological Constant
Universe, 2017 Cosmological constant corresponds to the maximally symmetric cosmological term with the equation of state p = − ρ . Introducing a cosmological term with the reduced symmetry, p r = − ρ in the spherically symmetric case, makes ...

Cosmological constant—the weight of the vacuum [PDF]
, 2002 Recent cosmological observations suggest the existence ofa positive cosmological constantwith the magnitude (G˝=c 3 ) ≈ 10 −123 . This review discusses several aspects ofthe cosmological constant both f rom the cosmological (Sections 1- 6) and .eld ...

Leading loop effects in pseudoscalar-Higgs portal dark matter
Journal of High Energy Physics, 2019 We examine a model with a fermionic dark matter candidate having pseudoscalar interaction with the standard model particles where its direct detection elastic scattering cross section at tree level is highly suppressed. We then calculate analytically the

The Existence and Effect of Dark Energy Redshift on Cosmological Age
Advances in Astronomy, 2020 A derivation of Cosmological Age explicitly constrained by Cosmic Microwave Background Radiation (CMBR) is presented, demonstrating that the correct value of Cosmological Age is equal to the Hubble Age. It is shown that utilizing “z = 0” for Cosmological

Hearing gravity from the cosmos: GWTC-2 probes general relativity at cosmological scales
Physics Letters B, 2021 Gravitational-wave (GW) catalogs are rapidly increasing in number, allowing for statistical analyses of the population of compact binaries. Nonetheless, GW inference of cosmology has typically relied on additional electromagnetic counterparts or galaxy ...
