Abstract: We investigate the conditions leading to large drag force fluctuations in granular materials. The study is based on a set of experimental drag tests, which involve pulling a plate vertically through a cohesionless granular material.… read more here.

DOI: 10.1093/mnras/sty1982
Abstract: Recently, Squire & Hopkins showed any coupled dust–gas mixture is subject to a class of linear ‘resonant drag instabilities’ (RDI). These can drive large dust-to-gas ratio fluctuations even at arbitrarily small dust-to-gas mass ratios μ.… read more here.
