Gamma-ray bursts (GRBs) are the most energetic explosions in the Universe. They are collimated, ultra-relativistic outflows which are powered by a central engine. When the ejected material starts to interact with the surrounding medium, shocks are formed where particles can be accelerated to emit synchrotron emission.

Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Many long gamma-ray bursts (GRBs) exhibit complex prompt emission structures with multiple temporally distinct episodes, such as early-time precursors preceding the main burst. Whether these subcomponents share the same physical origin and classification

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air
Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...

Spectral Line Search in Bright Gamma-Ray Bursts Observed by Fermi/GBM
The recently reported discoveries of emission lines with power-law decay from ∼37 to ∼6 MeV in the gamma-ray burst (GRB) 221009A have greatly contributed to probing the physics of GRBs, which also raises the natural question of whether there are more ...
