Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky. New observations, made using the Keck Cosmic Web Imager at th...
We present a catalogue of 17 filamentary X-ray features located within a 68 × 34 arcmin2 view centred on the Galactic Centre region from images taken by Chandra. These features are described by their ...
Dense core formation by fragmentation of velocity-coherent filaments in L1517
Stars: formation - ISM: clouds - molecules - kinematics and dynamics - structure - Radio lines: ISM

Context. Low-mass star-forming cores differ from their surrounding molecular cloud in turbulence, shape, and density structure. Aims. We aim to understand how dense cores form out of the less dense cl...
Oscillatory motions observed in eruptive filaments
Sun: fi laments prominences – Sun:oscillations – Sun:atmosphere.

Context: The origin of the variable component of the solar wind is of great intrinsic interest for heliophysics and space-weather, e.g. the initiation of coronal mass ejections, and the problem of mas...
Can overturning motions in penumbral filaments be detected?
overturning motions penumbral filaments detected

Numerical simulations indicate that the filamentation of sunspot penumbrae and the associated systematic outflow (the Evershed effect) are due to convectively driven fluid motions constrained by the i...
