The high spatial, temporal, and spectral resolution facilitates the measurement of gas temperatures and magnetic fields in the solar chromosphere with high precision. The anticipated results will revolutionize our understanding of the solar atmosphere and may in particular result in major steps towards solving the coronal heating problem. Based on state-of-the-art 3D radiation magnetohydrodynamic simulations, we calculate the emergent continuum intensity (and thus brightness temperature maps) in the wavelength range accessed by ALMA and simulate instrumental effects for different array configurations. First results show that the local gas temperature can be closely mapped with ALMA and that much of the complex small-scale chromospheric pattern can be resolved.", "revisions": [ { "version": "v1", "updated": "2015-02-12T09:58:22.000Z" } ], "analyses": { "keywords": [ "almas high-cadence imaging capabilities", "solar observations", "atacama large millimeter/submillimeter array offers", "state-of-the-art 3d radiation magnetohydrodynamic simulations", "gas temperature" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 2, "language": "en", "license": "arXiv", "status": "editable" } } }
