Source location and evolution of a multi-lane type II radio burst

P. Zucca, P. Zhang, K. Kozarev +8

Shocks in the solar corona can accelerate electrons that in turn generate radio emission known as type II radio bursts. The characteristics and morphology of these radio bursts in…

Modeling Metric Gyrosynchrotron Radio Emission From the Quiet Solar Corona

Kamen Kozarev, Mohamed Nedal

The radio emission of the quiet Sun in the metric and decametric bands has not been well studied historically due to limitations of existing instruments. It is nominally dominated…

Characterization of the Early Dynamics of Solar Coronal Bright Fronts

Mohamed Nedal, Kamen Kozarev, Rositsa Miteva +2

We present a comprehensive characterization of 26 CME-driven compressive waves known as Coronal Bright Fronts (CBFs) observed in the low solar corona between 2010 and 2017. These C…

Forecasting Solar Energetic Proton Integral Fluxes with Bi-Directional Long Short-Term Memory Neural Networks

Mohamed Nedal, Kamen Kozarev, Nestor Arsenov +1

Solar energetic particles are mainly protons and originate from the Sun during solar flares or coronal shock waves. Forecasting the Solar Energetic Protons (SEP) flux is critical f…

Multi-Scale Image Preprocessing and Feature Tracking for Remote CME Characterization

Oleg Stepanyuk, Kamen Kozarev, Mohamed Nedal

Coronal Mass Ejections (CMEs) influence the interplanetary environment over vast distances in the solar system by injecting huge clouds of fast solar plasma and energetic particles…

A Multi-Event Study of Early-Stage SEP Acceleration by CME-Driven Shocks -- Sun to 1 AU

Kamen Kozarev, Mohamed Nedal, Rositsa Miteva +2

The solar corona below 10 solar radii is an important region for early acceleration and transport of solar energetic particles (SEPs) by coronal mass ejection-driven shock waves. T…
