Shock wave propagation with high cadence solar ALMA time series

High cadence time series from solar ALMA observations are used to study shock wave propagation through the solar chromosphere. A carefully selected image reconstruction technique is used to retrieve reliable data, split into sub-bands, for this specific science case. This gives a tool to understand the small scale structure, complex dynamics and heat transfer in the chromosphere. In addition, synthetic observations from numerical simulations are used to give a qualified picture and valuable indications of how shock waves signatures appear in the observational data. Variations of the continuum brightness temperature across the ALMA receiver bands provide spectral signatures that allow to investigate the properties of shock waves and their propagation through the chromosphere. In turn, these results can be used as probes to study the chromosphere and as an aid in determining the radiative formation height of the ALMA receiver bands.
