Investigating the CREDIT History of Supernova Remnants as Cosmic-Ray Sources

The Astrophysical Journal Letters
Supernova remnants (SNRs) have long been suspected to be the primary sources of Galactic cosmic rays. Over the past decades, great strides have been made in the modeling of particle acceleration, magnetic field amplification, and escape from SNRs.

GOLD Nighttime Limb Observations: A New Data Set for Investigating the Altitude‐Latitude Structure and Temporal Variability of the Equatorial Ionization Anomaly

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using NASA's Global‐scale Observations of the Limb and Disk (GOLD)'s Dark Limb Mode (DLM) observations, we provide a multi‐year characterization of nighttime Equatorial Ionization Anomaly (EIA) morphology and variability. From geostationary orbit, GOLD measures OI 135.6 nm limb radiance at ∼33°E and ∼128°W longitudes, yielding routine, time ...

High Lithium Concentrations in Covalently Bonded Germanium Nanoparticle Assembled Layers

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
Germanium nanoparticles have a promising volumetric lithium storage capacity and are here synthesized by magnetron sputtering and lithiated to high concentrations to study the robustness against cracking. A detailed structural investigation following electrochemical lithium intercalation, using Raman spectroscopy, AFM, and XAFS provided detailed ...

Atmospheric monitoring for the H.E.S.S. experiment using a single scattering lidar [PDF]

, 2009
The High Energy Stereoscopic System (H.E.S.S.) is an array of 4 telescopes located in Namibia, which use the imaging atmospheric Cherenkov technique (IACT) to study astrophysical emission of gamma radiation in the energy window from 100 GeV to 50 TeV ...

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

Journal of Raman Spectroscopy, Volume 57, Issue 7, Page 1254-1266, July 2026.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

The Owl/Airwatch Experiment: the Focal Plane Detector

, 2000
We propose to observe Extensive Air Showers (EAS) produced by Extreme Energy Cosmic Rays (EECR) with an opto-electronic instrument mounted on a satellite (Owl/Airwatch concept, OA).

Radio emission of cosmic-ray air showers at the South Pole and a new icetop trigger

Schroeder, Frank G.The sources of highly energetic cosmic rays are still not fully understood. Better accuracy in composition measurement at different energies is essential to establish the origin of these energetic particles.

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 535-550, July/September 2026.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, Volume 42, Issue 6, Page 1115-1141, July 2026.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.
