Deciphering solar magnetic activity: The (solar) hale cycle terminator of 2021
Frontiers in Astronomy and Space Sciences, 2023 We previously identified an event in the solar timeline that appeared to play a role in how sunspot Cycle 23 (SC23) transitioned into sunspot Cycle 24 (SC24). The timeframe for this transition was rapid, taking place over a very short time and perhaps in

Frontiers in Astronomy and Space Sciences, 2022 Using multi-wavelength observations, we analysed magnetic field variations associated with a gradual X1.2 flare that erupted on January 7, 2014 in active region (AR) NOAA 11944 located near the disk center. A fast coronal mass ejection (CME) was observed

An Analysis of Image-Reading of Sun from Propositions of Active Intellect and Light of All Lights in Suhrawardi’s Symbolic Treatises [PDF]
ادبیات عرفانی, 2021 Mega-metaphors or central images, as propositions, contain profound thoughts originated from the mystic's personal experiences. Hence, decoding and clarifying the secondary meanings of these mega-metaphors will help to have a closer look at the mystic's ...

The dynamic chromosphere at millimeter wavelengths
Frontiers in Astronomy and Space Sciences, 2022 The chromosphere is one of the most complex and dynamic layers of the solar atmosphere. The dynamic phenomena occur on different spatial and temporal scales, not only in active regions but also in the so-called quiet Sun.

A Genetic Algorithm to Model Solar Radio Active Regions From 3D Magnetic Field Extrapolations
Frontiers in Astronomy and Space Sciences, 2022 In recent decades our understanding of solar active regions (ARs) has improved substantially due to observations made with better angular resolution and wider spectral coverage.
