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.

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.

Adapted Method for Separating Kinetic SZ Signal from Primary CMB Fluctuations
EURASIP Journal on Advances in Signal Processing, 2005 In this first attempt to extract a map of the kinetic Sunyaev-Zel'dovich (KSZ) temperature fluctuations from the cosmic microwave background (CMB) anisotropies, we use a method which is based on simple and minimal assumptions.

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).

Future Prospects on Constraining Neutrino Cosmology with the Ali CMB Polarization Telescope
The Astrophysical Journal, 2023 We forecast the constraints on the parameters of neutrino physics with the constructions of Cosmic Microwave Background (CMB) temperature, E-mode polarization, and lensing spectra for the ground-based Ali Cosmic Microwave Background Polarization ...

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
