Impacts of atmospheric river reconnaissance dropsondes on ECMWF Integrated Forecasting System precipitation forecasts

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
Impacts of Atmospheric River Reconnaissance dropsonde observations on precipitation forecasts over the U.S. West Coast are examined in the European Centre for Medium‐Range Weather Forecasts (ECMWF) Integrated Forecasting System (IFS), using observing‐system experiments.

The Impact of Population III.1 Flash Reionization for Cosmic Microwave Background Polarization and Thomson Scattering Optical Depth

The Astrophysical Journal Letters
The Population III.1 theory for supermassive black hole (SMBH) formation predicts a very early ( z  ∼ 20–25) transient phase, the “Pop III.1 Flash,” of cosmic reionization powered by supermassive stars that are SMBH progenitors. The Universe then quickly

Photoelectron Spectroscopy of the Phosphorus Monosulfide (PS) and Phosphorus Monoxide (PO) Radicals

Small Structures, Volume 7, Issue 1, January 2026.
Sketch of the experiment to measure the photo electron spectrum of the PS radical produced in situ with a mixture of PH3, H2S and F atoms. PO and PS radicals are the smallest units of phosphorus oxides and phosphorus sulfides, respectively, two rich families of refractory compounds widely employed in industrial and technological applications. These two

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.

The Cosmic Microwave Background Optical Depth Constrains the Duration of Reionization

The Astrophysical Journal Letters
Recently, it was pointed out that invoking a large value of the cosmic microwave background (CMB) optical depth, τ _CMB  = 0.09, could help resolve tensions between Dark Energy Survey Instrument DR2 baryon acoustic oscillation data and the CMB.

Gravitational Time Potential Energy

Advances in Astronomy, Volume 2026, Issue 1, 2026.
We extend the Einstein equivalence principle via a supplementary local energy equivalence postulate and propose the gravitational time potential energy (GTP) framework: a time‐dimensional scalar potential accumulating continuously with the proper duration of gravitational action. This framework may provide a potential classical interpretation for alpha

Nuclear Physics Meets the Sources of the Ultra-High Energy Cosmic Rays

Scientific Reports, 2017
The determination of the injection composition of cosmic ray nuclei within astrophysical sources requires sufficiently accurate descriptions of the source physics and the propagation – apart from controlling astrophysical uncertainties.

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).

Phenolic Compounds From Plant‐Based Material: Extraction and Biomedical Significance

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Phenolic compounds (PCs) are among the most widespread phytoconstituents found throughout the plant kingdom. These naturally occurring polyphenols have attracted remarkable scientific interest due to their potent antioxidant properties and their crucial role in mitigating oxidative stress‐related disorders, including cancer.
