Blue straggler formation at core collapse

open access: yes, 2016
Among the most striking feature of blue straggler stars (BSS) is the presence of multiple sequences of BSSs in the colour-magnitude diagrams (CMDs) of several globular clusters. It is often envisaged that such a multiple BSS sequence would arise due a recent core collapse of the host cluster, triggering a number of stellar collisions and binary mass ...

Metastability in Individual Magnetic Vortices at Low Temperatures

open access: yesSmall Structures, EarlyView.
Magnetic vortices are becoming increasingly important for quantum technologies, yet their behavior at low temperatures remains poorly understood. This study employs advanced ion beam nanofabrication and superconducting sensors to measure individual nanodiscs, revealing clear signatures of metastability. By precisely controlling nanoparticle morphology,

Gamma‐ray spectra and absorbed doses measured at EuXFEL undulator system

open access: yesJournal of Synchrotron Radiation, EarlyView.
The origin and composition of the stray radiation at the EuXFEL undulator system are investigated. This is essential for machine protection, as the stray radiation can damage the undulator permanent magnets as well as the correction and diagnostic equipment along the beamline.Characterization of the stray radiation field present in the undulator ...

Visual information in the dark: Bioluminescence and perceptual design through evolution

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bioluminescence offers a powerful framework for understanding how organisms evolve to shape visual information in diverse ways. Complementing studies of colour, transparency and pattern in illuminated environments, bioluminescent systems instead rely on generated light,
