Solar Radio Bursts Associated with In Situ Detected Energetic Electrons in Solar Cycles 23 and 24

Universe, 2022
The first comprehensive analysis between the in situ detected solar energetic electrons (SEEs) from ACE/EPAM satellite and remotely observed radio signatures in solar cycles (SCs) 23 and 24 (1997–2019) is presented.

Coronal Mass Ejections and Solar Radio Emissions (invited) [PDF]

PLANETARY RADIO EMISSIONS VII, 2011
Three types of low-frequency nonthermal radio bursts are associated with coronal mass ejections (CMEs): Type III bursts due to accelerated electrons propagating along open magnetic field lines, type II bursts due to electrons accelerated in shocks, and type IV bursts due to electrons trapped in post-eruption arcades behind CMEs.

Comparison of solar radio and EUV synoptic limb charts during the present solar maximum [PDF]

, 2016
The present solar cycle is particular in many aspects: it had a delayed rising phase, it is the weakest of the last 100 years, and it presents two peaks separated by more than one year.

The Connection of Solar Wind Parameters with Radio and UV Emission from Coronal Holes [PDF]

Solar Physics, 2011
This paper presents the results of a comparison between observations of coronal holes in UV (SOHO EIT) and radio emission (17, 5.7 GHz, 327 and 150.9 MHz, from NoRH, SSRT and Nancay radioheliographs), and solar wind parameters, from ACE spacecraft data over the period 12 March – 31 May 2007.

Radio Measurements of the Magnetic Field in the Solar Chromosphere and the Corona

Frontiers in Astronomy and Space Sciences, 2021
The structure of the upper solar atmosphere, on all observable scales, is intimately governed by the magnetic field. The same holds for a variety of solar phenomena that constitute solar activity, from tiny transient brightening to huge Coronal Mass ...
