From filamentary clouds to fibers feeding individual cores: how do filaments impact cloud and star formation?

Elongated ISM structures have been observed on cloud to Galactic arm scales since decades. They have now proven to be ubiquitous down to scales and densities approaching those of cores forming single stars. I will first present the constraints one has on the density structure of various filaments and their link to star-forming cores. I will then review the couple of observational and theoretical studies that suggest that gas flows toward gravitationally unstable filaments and cores. I will finally question if such a non-spherical and, most probably, non-continuous gas aggregation could modify the formation scenario of low-mass stars, high-mass stars, and mini-starburst clusters.
