"Constellation-X and JWST: Concurrent X-ray and Infrared Great Observatories"
Great synergy has been enjoyed between NASA's current Great Observatories and we expect that this will continue in the next decade with the concurrent operation of both Constellation-X and JWST.

Global Ionospheric Responses to Four X‐Class Solar Flares in November 2025
Abstract We investigate global ionospheric responses to four X‐class solar‐disk flares that occurred in November 2025 from the same solar active region, using multi‐instrument observations including GNSS, ionosonde, geomagnetic and GOES solar irradiance data. Pronounced dayside TEC enhancements are observed for three flares (#2 X1.2, #3 X5.1, and #4 X4.

TeV gamma-ray emission from accreting binary pulsars [PDF]
The high-mass X-ray binary SMC X-1 has been observed during the interval 1986-1989 at a threshold γ-ray energy of 0.4 TeV using the University of Durham Mark III air Cerenkov telescope at Narrabri.

A Study on the Geoeffective Event of 11 April 2022
Abstract Coronal Mass Ejections (CMEs) are the main drivers of geomagnetic storms. Studying their initial phases is important for understanding their propagation through the heliosphere and the effects they have on the Space Weather. In this work, as a case study, we investigate how SolO/Metis observations improve the accuracy in modeling a ...

View synthesis for depth from motion 3D x-ray imaging. [PDF]
The depth from motion or kinetic depth X-ray imaging (KDEX) technique is designed to enhance the luggage screening at airport checkpoints. The technique requires multiple views of the luggage to be obtained from an arrangement of linear X-ray detector ...

Energy Spectra of High Energy Helium An Extended and Improved Data Product From SOHO EPHIN
Abstract Context. The Electron Proton Helium INstrument (EPHIN) aboard the SOlar and Heliospheric Observatory (SOHO) is a particle telescope that measures energetic protons and Helium particles with kinetic energies above 4 MeV/nuc and electrons with kinetic energies above 150 KeV. Located at the Lagrangian point L1 of the Earth‐Sun system, it provides

The May 2024 Storm: The Cusps and Dayside Magnetopause in Simulated Soft X‐Rays
Abstract The coronal mass ejection (CME) arriving at Earth on 10 May 2024 caused the most intense geomagnetic storm in the last two decades, resulting in highly unusual cusp and magnetopause dynamics. We simulate soft X‐Ray emission due to solar wind charge exchange with exospheric neutrals to image the global dayside dynamics, focusing on the impact ...

Abstract Atmospheric mineral dust and black carbon (BC) aerosols play important roles in the Earth's climate system, yet direct observations over the Southern Ocean (SO) are scarce. In this study, we present the characteristics of airborne water‐insoluble particles (WIPs) collected during a cruise of the R/V Shirase in the Australian and Indian sectors

X-ray Observations of Cosmic Ray Acceleration [PDF]
Since the discovery of cosmic rays, detection of their sources has remained elusive. A major breakthrough has come through the identification of synchrotron X-rays from the shocks of supernova remnants through imaging and spectroscopic observations by ...
