DOI: 10.1016/j.jastp.2021.105616
Abstract: Abstract The auroral oval is a well-established concept, introduced more than five decades ago. The Alfvenic oval, on the other hand, is a very recent concept, which has been revealed in both observational and numerical… read more here.

DOI: 10.1029/2020ja028059
Abstract: Motivated by low-altitude cusp observations of small-scale (~ 1 km) field-aligned currents (SSFACs) interpreted as ionospheric Alfven resonator modes, we have investigated the effects of Alf... read more here.

DOI: 10.1051/0004-6361/202039442
Abstract: Context. Parker Solar Probe’s first solar encounter has revealed the presence of sudden magnetic field deflections that are called switchbacks and are associated with proton velocity enhancements in the slow alfvénic solar wind. Aims. We… read more here.

DOI: 10.1051/0004-6361/202039818
Abstract: Context. Parker Solar Probe (PSP) measures the magnetic field and plasma parameters of the solar wind at unprecedentedly close distances to the Sun. These data provide great opportunities to study the early-stage evolution of magnetohydrodynamic… read more here.

DOI: 10.1088/1741-4326/ab2ca2
Abstract: Ion cyclotron emission (ICE) is detected from all large toroidal magnetically con ned fusion (MCF) plasmas. It is a form of spontaneous suprathermal radiation, whose spectral peak frequencies correspond to sequential cyclotron harmonics of energetic… read more here.

DOI: 10.1088/1741-4326/ac054c
Abstract: Fusion-born alpha particles in ITER disruption simulations are investigated as a possible drive of Alfvénic instabilities. The ability of these waves to expel runaway electron (RE) seed particles is explored in the pursuit of a… read more here.
