Abstract

We propose to numerically model coronal "supra-arcade downflows" (SADs) withthe aim to infer their physical triggers using an almost unexplored approximation not systematized so far. The project is divided in two parts: (i) look for SADs signaturesat microwaves, estimating relevant observational parameters to restrict their possiblevalues; and (ii) include the empirical parameters found as inputs in the numerical MHD modellings of SADs. The main objective is to model more accurately the coronal background and the physical processes that trigger the SADs with the help of new observational constraints, shedding light on the validity of different SADs' models present currently in the literature.
