Soft X‐Ray Imaging of Dense and Fast Magnetosheath Jets: Numerical Simulations

Earth and Space Science
The goal of this paper is to estimate the soft X‐ray signature associated with dense and fast magnetosheath jets streaming toward the dayside magnetosphere. We developed a non‐self‐consistent kinematic approach for simulating numerically the transport of

Probing the Transition Between the Synchrotron and Inverse-compton Spectral Components of 1ES 1959+650

, 2010
1ES 1959+650 is one of the most remarkable high-peaked BL Lacertae objects (HBL). In 2002, it exhibited a TeV gamma-ray flare without a similar brightening of the synchrotron component at lower energies.

The Mass of the Black Hole in LMC X-3 [PDF]

, 2014
We analyze a large set of new and archival photometric and spectroscopic observations of LMC X-3 to arrive at a self-consistent dynamical model for the system.

Stepwise Regulation of Cellular Oxidative Stress via Conductive‐Piezoelectric Integrated Microstructured Conduits for Enhanced Nerve Regeneration

Advanced Science, EarlyView.
This study presents a conductive‐piezoelectric integrated microstructured conduit for peripheral nerve regeneration. The conduit combines reduced graphene oxide with a piezoelectric nanofiber membrane, enhancing nerve repair through physical guidance, oxidative stress inhibition, and ultrasound‐activated electrical stimulation.

Evidence for GeV Gamma-Ray Emission from Intense GRB 240529A During the Afterglow’s Shallow Decay Phase

The Astrophysical Journal
X-ray light curves of gamma-ray burst (GRB) afterglows exhibit various features, with the shallow decay phase being particularly puzzling. While some studies report the absence of the X-ray shallow decay for hyperenergetic GRBs, recently discovered GRB ...

GRBs and Lobster Eye X-Ray Telescopes [PDF]

EAS Publications Series, 2013
A large majority of GRBs exhibit X-ray emission. In addition, a dedicated separate group of GRB, the XRFs, exists which emission dominates in the X-ray spectral range. And the third group of GRB related objects (yet hypothetical) are the group of off-axis observed GRBs (orphan afterglows).
