The first science papers from the ALMA Large Program ARKS (ALMA survey to Resolve exoKuiper belt Substructures), which was supported by the UK ARC Node, have now been published in Astronomy & Astrophysics. This project performed a survey of 24 debris discs with the goal of mapping and measuring the radial and vertical extent of the dust within these discs as well as characterizing the gas content within them. A broad range of structures were seen in these objects, including rings with gaps, asymmetries, and vertically puffed-up structures. More details are given in the press released on the ALMA and NRAO websites.
