The Chinese Radio Telescope Array for Interplanetary Scintillation Monitoring

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Solar flares, coronal mass ejections (CMEs) and enegertic particles, etc., are the driving sources that may cause catastrophic space weathers. It is desirable to obtain information of solar eruptions like flares and CMEs, etc., propagating from the Sun to the near‐Earth space.

A Measurement of Atmospheric Circular Polarization with POLARBEAR

The Astrophysical Journal
At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth's magnetic field.

The Cosmic Microwave Background and Particle Physics [PDF]

, 1999
In forthcoming years, connections between cosmology and particle physics will be made increasingly important with the advent of a new generation of cosmic microwave background (CMB) experiments. Here, we review a number of these links.

Unexpected topology of the temperature fluctuations in the cosmic microwave background [PDF]

Astronomy & Astrophysics, 2018
We study the topology generated by the temperature fluctuations of the cosmic microwave background (CMB) radiation, as quantified by the number of components and holes, formally given by the Betti numbers, in the growing excursion sets.

Testing the Weak Cosmic Censorship Conjecture via Test Particle–Induced Overcharging/Overspinning of Kerr–Newman–Modified Gravity Black Hole

Advances in Astronomy, Volume 2026, Issue 1, 2026.
We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Impact of Interacting Parameters on Dark Matter in an Interacting Dark Energy Model

The Astrophysical Journal Supplement Series
This paper investigates a dark energy model within the Friedmann–Lemaître–Robertson–Walker cosmological framework, considering both interacting and noninteracting scenarios.

Lorentz invariance violation in the neutrino sector: a joint analysis from big bang nucleosynthesis and the cosmic microwave background

European Physical Journal C: Particles and Fields, 2017
We investigate constraints on Lorentz invariance violation in the neutrino sector from a joint analysis of big bang nucleosynthesis and the cosmic microwave background.

Cosmic Microwave Background Anisotropies from Scaling Seeds: Fit to Observational Data [PDF]

, 1997
We compute cosmic microwave background angular power spectra for scaling seed models of structure formation. A generic parameterization of the energy momentum tensor of the seeds is employed.

Exploring the Tension between Current Cosmic Microwave Background and Cosmic Shear Data

Symmetry, 2018
This paper provides a snapshot of the formal S 8 ≡ σ 8 Ω m / 0.3 tension between Planck 2015 and the Kilo Degree Survey of450 deg 2 of imaging data (KiDS-450) or the Canada France Hawaii Lensing Survey (CFHTLenS).

Stratosphere‐Troposphere Exchange of Water Vapor Based on Observations and Reanalyses

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract This study provides the first estimates of the global stratosphere‐troposphere exchange (STE) of water vapor (H2O) using the lowermost stratosphere mass budget approach. Observationally derived H2O fluxes across the isentropic surface fitted to the tropical tropopause are −1.16 ± 0.20 Pg/yr in the Northern Hemisphere extratropics, −0.94 ± 0.18
