The IAC presents a public outreach video about the project “Polarized Radiation Diagnostics for Exploring the Magnetism of the Outer Solar Atmosphere” (POLMAG). In this video, several POLMAG scientists explain the basic aspects of the project. The POLMAG research group was created in January 2018 within the framework of the Advanced Grant awarded by the European Research Council (ERC) to Javier Trujillo Bueno (CSIC Research Professor and IAC Senior Scientist).
POLMAG aims at novel advances in the development and application of polarized radiation diagnostic methods for exploring the magnetic fields of the chromosphere, transition region and corona of the Sun. The methods being developed are based on the polarization signals produced by optically polarized atoms and the Hanle and Zeeman effects in ultraviolet (UV), visible and near-infrared spectral lines. Such methods are of great interest for exploiting the unprecedented spectropolarimetric observations that the new generation of ground-based and space telescopes are making possible, or will make possible, such as DKIST, EST and CLASP.
POLMAG combines and expands expertise on atomic physics, on the quantum theory of radiation, on high-precision spectropolarimetry, on advanced methods in numerical radiative transfer, and on the confrontation of spectropolarimetric observations with spectral synthesis in increasingly realistic three-dimensional (3D) numerical models of the solar atmosphere.
The scientists that participate in the video are Javier Trujillo Bueno, Sara Esteban Pozuelo, Andrii Sukhorukov, Supriya Hebbur Dayananda, Tanausú del Pino Alemán and Ángel de Vicente Garrido.
