Supervised Extraction of the Thermal Sunyaev–Zel’dovich Effect with a Three-dimensional Convolutional Neural Network

The Astrophysical Journal
The thermal Sunyaev–Zel’dovich (SZ) effect offers a unique probe of the hot and diffuse Universe that could help close the missing baryon problem. Traditional extractions of the SZ effect, however, exhibit systematic noise that may lead to unreliable ...

A New Constraint on the Optical Depth from the Reionization History Independent of Cosmic Microwave Background Large-scale E-mode Polarization

The Astrophysical Journal
Recent studies report a mild discrepancy between baryon acoustic oscillation (BAO) and cosmic microwave background (CMB) measurements within the ΛCDM framework.

Constraining dark energy using real and mock galaxy surveys [PDF]

, 2009
In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

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.

On the origin of cosmic microwave background radiation

The alternative mechanism of the emergence of cosmic microwave background radiation (CMB), associated with the thermal radiation of primordial gas-dust clouds in the early Universe, is considered. The emergence of such clouds in the theory of infinite hierarchical nesting of matter is a natural stage in matter evolution.
