A Global Stocktake on Electricity Access and Gaps From NASA Black Marble Nighttime Lights

Earth's Future, Volume 13, Issue 6, June 2025.
Abstract Electricity is a basic human necessity. We are highly reliant on continuous access to electricity for our health, well‐being, and it remains essential for critical infrastructure, industries, and human development. Yet, there remains a gap in populations with access to electricity across the globe.

The Relationship Between EUV Nonthermal Line Broadening and High-energy Particle During Solar Flare [PDF]

, 2013
We have studied the relationship between the location of EUV nonthermal broadening and high-energy particles during the large flares by using EUV imaging spectrometer onboard {\it Hinode}, Nobeyama Radio Polarimeter, Nobeyama Radioheliograph, and Atmospheric Imaging Assembly onboard {\it Solar Dynamic Observatory}. We have analyzed the five large flare

Ionospheric Analysis With Martian Mutual Radio Occultation

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract This study presents a comprehensive analysis of the Martian ionosphere using Mutual Radio Occultation (RO) observations between Mars Express and Trace Gas Orbiter, featuring 71 full vertical profiles out of a total of 124 measurements. Among these, 35 measurements were taken from regions with Solar Zenith Angles lower than 40°.

The Shape of M Dwarf Flares in Kepler Light Curves [PDF]

, 2015
Ultra-precise light curves from Kepler provide the best opportunity to determine rates and statistical properties of stellar flares. From 11 months of data on the active M4 dwarf, GJ 1243, we have built the largest catalog of flares for a single star: over 6100 events.

Helioseismic response to X2.2 solar flare of February 15, 2011

, 2011
The X2.2-class solar flare of February 15, 2011, produced a powerful sunquake event, representing a helioseismic response to the flare impact in the solar photosphere, which was observed with the HMI instrument on the Solar Dynamics Observatory (SDO ...

Multitaper Magnitude‐Squared Coherence for Time Series With Missing Data: Understanding Oscillatory Processes Traced by Multiple Observables

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract To explore the hypothesis of a common source of variability in two time series, observers may estimate the magnitude‐squared coherence (MSC), which is a frequency‐domain view of the cross correlation. For time series that do not have uniform observing cadence, MSC can be estimated using Welch's overlapping segment averaging.

The role of eruption in solar flares [PDF]

Solar Physics, 1989
AbstractThis article focuses on two problems involved in the development of models of solar flares. The first concerns the mechanism responsible for eruptions, such as erupting filaments or coronal mass ejections, that are sometimes involved in the flare process.

Detecting Solar Neutrino Flare in Megaton and km^3 detectors

, 2009
To foresee a solar flare neutrino signal we infer its upper and lower bound. The upper bound was derived since a few years by general energy equipartition arguments on observed solar particle flare.

Variation of Model‐Predicted Reconnection Voltages Applied to Uranus' Dayside Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Uranus provides a key missing piece for fundamentally understanding solar wind‐magnetospheric interactions due to its location in the outer solar system. Whether the viscous‐like interaction overtakes global magnetic reconnection as the dominant process at the magnetopause of the outer planets remains unresolved.
