High-resolution observations with ARTEMIS/JLS and the NRH: IV. Imaging spectroscopy of spike-like structures near the front of type-II bursts
S. Armatas, C. Bouratzis, A. Hillaris +5
Narrowband bursts (spikes) appear on dynamic spectra from microwave to decametric frequencies. They are believed to be manifestations of small-scale energy release through magnetic…
High resolution observations with Artemis--JLS, (II) Type IV associated intermediate drift bursts
C. Bouratzis, A. Hillaris, C. E. Alissandrakis +5
Aims. We examined the characteristics of isolated intermediate drift bursts (IMDs) and their morphologies on dynamic spectra, in particular the positioning of emission and absorpti…
Detection of spike-like structures near the front of type-II bursts
S. Armatas, C. Bouratzis, A. Hillaris +6
Aims. We examine high time resolution dynamic spectra for fine structures in type II solar radio bursts Methods. We used data obtained with the (SAO) receiver of the Artemis-JLS (A…
A Wavelet Based Approach to Solar--Terrestrial Coupling
Ch. Katsavrias, A. Hillaris, P. Preka--Papadema
Transient and recurrent solar activity drive geomagnetic disturbances; these are quantified (amongst others) by DST, AE indices time-series. Transient disturbances are related to t…
Fine Structure of Metric Type-IV Radio Bursts Observed with the ARTEMIS-IV Radio Spectrograph: Association with Flares and Coronal Mass Ejections
C. Bouratzis, A. Hillaris, C. E. Alissandrakis +5
Fine structures embedded in type-IV burst continua may be used as diagnostics of the magnetic field restructuring and the corresponding energy release associated with the low coron…
CME Expansion as the Driver of Metric Type II Shock Emission as Revealed by Self-Consistent Analysis of High Cadence EUV Images and Radio Spectrograms
A. Kouloumvakos, S. Patsourakos, A. Hillaris +6
On 13 June 2010, an eruptive event occurred near the solar limb. It included a small filament eruption and the onset of a relatively narrow coronal mass ejection (CME) surrounded b…
