New Insights into Type-I Solar Noise Storms from High Angular Resolution Spectroscopic Imaging with the Upgraded Giant Metrewave Radio Telescope

open access: yesThe Astrophysical Journal
Type-I solar noise storms are perhaps the most commonly observed active radio emissions from the Sun at meter-wavelengths. Noise storms have a long-lived and wideband continuum background with superposed islands of much brighter narrowband and short ...

Automated coronal hole identification via multi-thermal intensity segmentation

open access: yesJournal of Space Weather and Space Climate, 2018
Coronal holes (CH) are regions of open magnetic fields that appear as dark areas in the solar corona due to their low density and temperature compared to the surrounding quiet corona.

Beyond Electrochemical Innovation: Prioritizing Industry Standard Abuse Testing for Safe Lithium Metal Batteries

open access: yesEnergy Technology, Volume 14, Issue 7, July 2026.
This critical review evaluates recent material and architectural innovations in lithium metal batteries against the strict frameworks of industry standard abuse testing. By analyzing the disconnect between benchtop electrochemical performance and macroscale safety validation, the review highlights the urgent need to transition from low scale cell ...

Heat and Dust Impacts on the Health of Refugees in Zaatari Refugee Camp

open access: yesGeoHealth, Volume 10, Issue 7, July 2026.
Abstract Climate‐linked heatwaves and dust storms can exacerbate non‐communicable disease (NCD) morbidity, yet quantitative evidence from displacement settings remains limited. We assessed short‐term impacts of heat and dust events on symptom burden among Syrian refugees with non‐communicable diseases (NCDs) in Jordan's Zaatari Camp.

Estimating Electron Densities in the Middle Solar Corona Using White-light and Radio Observations

open access: yesThe Astrophysical Journal
The electron density of the solar corona is a fundamental parameter in many areas of solar physics. Traditionally, routine estimates of coronal density have relied exclusively on white-light observations.

The Effect of the Parametric Decay Instability on the Morphology of Coronal Type III Radio Bursts

open access: yesThe Astrophysical Journal Letters, 2023
The nonlinear evolution of Alfvén waves in the solar corona leads to the generation of Alfvénic turbulence. This description of the Alfvén waves involves parametric instabilities where the parent wave decays into slow mode waves giving rise to density ...

Interplanetary Tracking of the 23 March 2024 CME: Computer Tomographic Analyses of IPS, White‐Light, and Type II Radio Burst Observations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract We analyze the propagation of a coronal mass ejection (CME) observed on 23 March 2024, at 01:25 UT by SOHO/LASCO using a multi‐instrument and multi‐method approach. The study combines Interplanetary Scintillation (IPS), type II radio bursts, white‐light, in‐situ observations, and 3D tomographic reconstruction of the inner heliospheric density.

Are Nonthermal Velocities in Active Region Coronal Loops Anisotropic?

open access: yesThe Astrophysical Journal, 2023
We have measured line widths in active region coronal loops in order to determine whether the nonthermal broadening is anisotropic with respect to the magnetic field direction. These nonthermal velocities are caused by unresolved fluid motions.

Radio Measurements of the Magnetic Field in the Solar Chromosphere and the Corona

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The structure of the upper solar atmosphere, on all observable scales, is intimately governed by the magnetic field. The same holds for a variety of solar phenomena that constitute solar activity, from tiny transient brightening to huge Coronal Mass ...

Muon Flux Fluctuations and Solar Phenomena Using Regional Geomagnetic Indices With a Cosmic Ray Detector in Mexico City

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The data from a cosmic ray (CR) detector in Mexico City were collected over a period of 2 years from September 2023 to September 2025, during the maximum phase of Solar Cycle 25. The CR detector consists of an array of scintillators and measures the muonic component of secondary CRs.
