Advanced Engineering Materials, Volume 27, Issue 24, December 2025.Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Nonlinear Transmission of Strong THz‐Electric Fields Through Thin Gold Films
Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.Gold is is the prime metal for imaging THz radiation. This study demonstrates that the interaction of strong THz pulses with gold becomes nonlinear at certain peak THz‐electric field strengths. The strong fields change the electron density of states which contributing to the absorption of the propagating THz pulse.

Jupiter's X‐ray Aurorae. A High Signal Spectral Analysis of the 0.24–1.40 keV Energy Range
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract Jupiter's X‐ray auroras are predominantly produced by precipitating energetic heavy ions. Recent results suggest a connection between the pulsation rate of these ion aurorae and the pulsation rate of magnetospheric waves. Using remote X‐ray observations and results from in situ measurements from the Juno Jupiter Energetic particle Detector ...

Dormant black hole candidates from Gaia DR3 summary diagnostics
Astronomy & AstrophysicsWe present a rigorous identification of candidates for dormant black holes (BHs) and neutron stars (NSs) in binaries using summary statistics from Gaia Data Release 3 (DR3), rather than full orbital solutions.
