Abhishek Kumar Srivastava is a Professor of Physics at the Indian Institute of Technology (Banaras Hindu University), Varanasi, India. He works in the field of solar and heliospheric physics, and his research focuses on the study of magnetohydrodynamic waves, coronal heating, various solar eruptive phenomena and transients in the Sun's atmosphere. Marcel Goossens is professor emeritus in Applied Mathematics in the Centre of mathematical Plasma Astrophysics of the Department of Mathematics of the KU Leuven. His research spans more than five decades and has dealt with global stellar oscillations, magnetohydrodynamic waves and instabilities in solar and space plasmas, and magnetohydrodynamic seismology of the solar atmosphere. Iñigo Arregui is a physicist working as a staff researcher at the Instituto de Astrofísica de Canarias. He completed a PhD in Physics at Universitat de les Illes Balears with a thesis on magnetohydrodynamic waves in the solar atmosphere. His research focuses on the interpretation and modelling of wave activity in the solar atmosphere, designing tools for remote diagnostics of solar atmospheric plasmas, and the study of wave-based plasma heating mechanisms.
