Special Issue on Modified Gravity Approaches to the Tensions of ΛCDM: Goals and Highlights

Universe
The standard cosmological model, known as ΛCDM, has been remarkably successful in providing a coherent and predictive framework for understanding the Universe’s evolution, its large-scale structure, and cosmic microwave background (CMB) radiation [...]

CMB-S4: Foreground-cleaning Pipeline Comparison for Measuring Primordial Gravitational Waves

The Astrophysical Journal
We compare multiple foreground-cleaning pipelines for estimating the tensor-to-scalar ratio, r , using simulated maps of the planned CMB-S4 experiment within the context of the South Pole Deep Patch.

BICEP/Keck. XX. Component-separated Maps of the Polarized Cosmic Microwave Background and Thermal Dust Emission Using Planck and BICEP/Keck Observations through the 2018 Observing Season

The Astrophysical Journal
We present component-separated polarization maps of the cosmic microwave background (CMB) and Galactic thermal dust emission, derived using data from the BICEP/Keck experiments through the 2018 observing season and Planck.

Can Chameleon Fields Be the Source of the Dark Energy Dipole and the Cosmic Microwave Background Dipole?

The Astrophysical Journal
Recent research reveals that the Local Group is in motion toward ( l , b ) = (276, 30) relative to the cosmic background radiation, manifesting a velocity of 600 km s ^−1 , a phenomenon recognized as the cosmic background radiation dipole or cosmic ...

Evaluation of the Single-component Thermal Dust Emission Model in Cosmic Microwave Background Experiments

The Astrophysical Journal Supplement Series
It is well known that multiple Galactic thermal dust emission components may exist along the line of sight, but a single-component approximation is still widely used, since a full multicomponent estimation requires a large number of frequency bands that ...
