An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout

Analysis of CME Interactions in Solar Corona Combining Coronagraphic Observations with Wide-field Imagers from Solar Orbiter and Parker Solar Probe

The Astrophysical Journal
Accurately determining the trajectory of coronal mass ejections (CMEs) is vital for space weather forecasting and assessing their potential impact on Earth. CMEs often deviate from a radial path, due to local pressure gradients or interactions with other

The roles of jets: CF, CCSN, PN, CEE, GEE, ILOT

, 2015
I review the roles of jet-inflated bubbles in determining the evolution of different astrophysical objects. I discuss astrophysical systems where jets are known to inflate bubbles (cooling flow [CF] clusters; young galaxies; intermediate luminosity ...

Determining the Magnetopause Location With SMILE‐SXI Using a Constrained Solar Wind Independent SWCX Model

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract The soft X‐ray imager (SXI) on the SMILE mission promises to revolutionize our understanding of the magnetopause by observing solar wind charge exchange emission from the magnetosheath on a global scale. The primary goal of this instrument is to infer the position and shape of the magnetopause from these images.

TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc

The Astrophysical Journal Letters
We present the Transiting Exoplanet Survey Satellite (TESS) discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling comparisons with the β Pictoris and

On the role of magnetic reconnection in jet/accretion disk systems

, 2009
The most accepted model for jet production is based on the magneto-centrifugal acceleration out off an accretion disk that surrounds the central source (Blandford & Payne, 1982). This scenario, however, does not explain, e.g., the quasi-periodic ejection

Mountain Degradation Mechanisms on Io Based on Geologic Mapping of the Cocytus Montes Region From JunoCam Imagery

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Periodic high‐resolution imagery of Io is essential for understanding its surface evolution, from volcanic eruptions to tectonic deformation to large‐scale mass wasting. Juno flybys in 2023 and 2024 obtained imagery of the surface with the JunoCam imager at 1.8 km/pixel spatial resolution, comparable to global observations from the Galileo ...

Two-Temperature Magnetohydrodynamics Simulations of Propagation of Semi-Relativistic Jets

Galaxies, 2019
In astrophysical jets observed in active galactic nuclei and in microquasars, the energy exchange rate by Coulomb collision is insufficient for thermal equilibrium between ions and electrons.
