Dear friends,

 

You might be interested in the attached paper by Vadim Uritsky and me concerning the shapes of loop cross sections. Vadim compared intensity traces across loops in real images from Hi-C and synthetic images generated with a variety of assumed cross-sectional shapes. By applying several statistical measures, we concluded that the Hi-C loops tend to be more “tube like” (roughly circular cross sections) than ribbon like or veil like. This is consistent with the findings of two other Hi-C observational papers (Klimchuk & DeForest, 2020, ApJ, 900, 167; Williams, Walsh, & Morgan, 2021, ApJ, 919, 47) and a recent paper by Sudip Mandal and colleagues using EUI/SolO data, also attached.

 

Cheers,

Jim
