Gamma-Ray Burst Timing: Decoding the Hidden Slow Jets in GRB 060729

The Astrophysical Journal Letters
Gamma-ray bursts (GRBs) are luminous stellar explosions characterized by the ejection of relativistic jets. This work proposes a novel paradigm to study these GRB jets. By analyzing the timing information of prompt pulses and X-ray flares, in conjunction

Multiwavelength Campaign Observations of a Young Solar-type Star, EK Draconis. III. Comparison between Starspot Mapping, Zeeman Doppler Imaging, and Multiwavelength Variability

The Astrophysical Journal
Recent simultaneous multiwavelength observations of a nearby young solar-type star EK Draconis (EK Dra) in the optical, H α spectrum, and X-ray, have provided evidence for stellar prominence eruptions associated with superflares.

The high energy X-ray probe (HEX-P): Resolving the nature of Sgr A* flares, compact object binaries and diffuse X-ray emission in the Galactic center and beyond

Frontiers in Astronomy and Space Sciences
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging (<10″ FWHM) and broad spectral coverage (0.2–80 keV) with an effective area far superior to current facilities’ (including XMM-Newton and NuSTAR).

Lost in Translation: Why Biologic Therapies for Intervertebral Disc Degeneration and Low Back Pain Have Not Reached the Clinic (Yet)

JOR SPINE, Volume 9, Issue 3, September 2026.
From preclinical promise to clinical translation in intervertebral disc degeneration (IDD). Robust preclinical evidence supports a range of biologic therapies, with consistent improvements in imaging, extracellular matrix composition, inflammation, and behavior.

Detecting Stellar Coronal Mass Ejections via Coronal Dimming in the Extreme Ultraviolet

The Astrophysical Journal
Stellar flares and coronal mass ejections (CMEs) can strip planetary atmospheres, reducing the potential habitability of terrestrial planets. While flares have been observed for decades, stellar CMEs remain elusive.

AD Leo from X-Rays to Radio: Are Flares Responsible for the Heating of Stellar Coronae?

, 2000
In spring 1999, a long coordinated observing campaign was performed on the flare star AD Leo, including {\it EUVE}, {\it BeppoSAX}, the {\it VLA}, and optical telescopes. The campaign covered a total of 44 days. We obtained high-quality light curves displaying ongoing variability on various timescales, raising interesting questions on the role of flare-

Multiwavelength Study of a Superflare on RS CVn–Type Star HD 22468 Triggered at Hard X-Ray by SVOM

The Astrophysical Journal
Detection of stellar flares at hard X-ray is still rare at the current stage. A transient was recently detected by the hard X-ray camera ECLAIRs on board the SVOM mission at 11:39:01.2 UT on 2025 January 09. Simultaneous monitoring in the optical band on
