Nearly Full-sky Low-multipole Cosmic Microwave Background Temperature Anisotropy. III. Cosmic Microwave Background Anomalies

The Astrophysical Journal
Unexpected features have been observed in the cosmic microwave background (CMB) temperature on large scales. We revisit these CMB anomalies using new foreground-cleaned CMB temperature maps derived in a companion paper from WMAP and Planck data, which ...

Delensing of Cosmic Microwave Background Polarization with Machine Learning

The Astrophysical Journal Supplement Series, 2023
Primordial B -mode detection is one of the main goals of next-generation cosmic microwave background (CMB) experiments. Primordial B -modes are a unique signature of primordial gravitational waves (PGWs).

Different Explanations for the Cosmic Microwave Background Radiation

, 2021
In this research, the other reasonable explanations for the cosmic microwave background radiation is revealed. Due to the microwave resolution, it very roughly shows the image of galaxies in the universe. Moreover, the intensity measurement on each pixel of the image is the sum of the incident microwaves from different directions, so the microwave ...

Capturing Field‐Scale Soil Moisture Dynamics in Ireland Using Cosmic‐Ray Neutron Sensing

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.
Schematic overview of the study, including the monitoring setup, field observations, and the principal findings. ABSTRACT Cosmic‐Ray Neutron Sensing (CRNS) enables non‐invasive monitoring of field‐scale soil moisture, bridging the spatial gap between point‐scale sensors such as Time Domain Reflectometry (TDR) and coarse‐resolution satellite products ...

The Simons Observatory: Detector Polarization Angle Calibration Using a Sparse Wire Grid with Initial Datasets of the Small-aperture Telescopes

The Astrophysical Journal Supplement Series
Improved measurements of B -modes in the cosmic microwave background can be obtained through accurate calibration of the orientation of detector antennas as projected onto the sky. Miscalibration of the detector polarization angle leads to a leakage of E

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

Systems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Simons Observatory: Characterization of the Large Aperture Telescope Receiver

The Astrophysical Journal Supplement Series
The Simons Observatory (SO) is a ground-based cosmic microwave background (CMB) survey experiment that currently consists of three 0.42 m small-aperture telescopes and one 6 m large-aperture telescope (LAT), located at an elevation of 5200 m in the ...

Recovering Cosmic Microwave Background Polarization Signals with Machine Learning

The Astrophysical Journal, 2023
Primordial B-mode detection is one of the main goals of current and future cosmic microwave background (CMB) experiments. However, the weak B-mode signal is overshadowed by several Galactic polarized emissions, such as thermal dust emission and ...

An Grided Soil Moisture Profile Data Set Based on an Optimal Land Surface Model With Measured Hydraulic Parameters and Data Assimilation Over the Loess Plateau

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Soil moisture (SM) is a key water source for vegetation, directly determining the success of revegetation efforts in water‐limited regions. However, accurate profile SM data remain lacking for the Chinese Loess Plateau (LP), limiting ecological restoration efforts.

Microwave Radiation

, 2015
Microwave radiation is a form of electromagnetic radiation. It covers, broadly speaking, frequencies between 300 MHz and 300 GHz. For example a microwave oven operates at a frequency of 2.45 GHz and many mobile network providers use frequencies between ...
