We review basic theoretical concepts in particle acceleration, with particular emphasis on
processes likely to occur in regions of magnetic reconnection. Several new developments …

Abstract The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful tool for
observing the Sun at high spatial, temporal, and spectral resolution. These capabilities can …

Magnetic reconnection plays a crucial role in powering solar flares, production of energetic
particles, and plasma heating. However, where the magnetic reconnections occur, how and …

Incoherent solar radio radiation comes from the free-free, gyroresonance, and
gyrosynchrotron emission mechanisms. Free-free is primarily produced from Coulomb …

We review recent progress on our understanding of radio emission from solar flares and
coronal mass ejections (CMEs) with emphasis on those aspects of the subject that help us …

Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's
variability, the surrounding heliosphere, and the environment and climate of planets. The …

We identify a set of∼ 100" cold" solar flares and perform a statistical analysis of them in the
microwave range. Cold flares are characterized by a weak thermal response relative to …

The interrelation of hard X-ray (HXR) emitting sources and the underlying physics of electron
acceleration and transport presents one of the major questions in high-energy solar flare …

We have developed a general framework for modeling gyrosynchrotron and free–free
emission from solar flaring loops and used it to test the premise that 2D maps of source …

Astrophysics is a highly important part of the modern vision of the world around us. Over the
past century, it has transformed the very foundation and basic philosophical concepts on the …
