Flare-associated hot coronal loops often display compressive plasma oscillations involving a density perturbation moving back and forth between the foot points of the loop. These oscillations, sometimes referred to as, ``sloshing oscillations", exhibit properties very similar to the standing slow waves that were discovered much earlier with the SoHO/SUMER and other spectroscopic instruments....
The Nuclear Spectroscopic Telescope Array (NuSTAR) is an astrophysical X-ray telescope capable of observing the Sun with direct imaging spectroscopy providing a unique sensitivity above 2.5 keV. We use NuSTAR to investigate highly frequent and weak flares thought to contribute to heating the Sun's atmosphere particularly in active regions. I will present several X-ray microflares from a...
Energy transport by fast, non-thermal particles from primary energy release place - located in the top of flaring loop - to the loop foot-points, plays very important role in solar flares. A fully understanding of the processes of transportation, energy deposition in the chromosphere and radiative response of chrompospheric plasma requires both: high (sub-second) cadence observations and...
Estimates of coronal wave energies remain uncertain as a large fraction is hidden in the non-thermal line widths of emission lines. To estimate these wave energies, previous studies have taken the root mean squared wave amplitudes to be a factor of $\sqrt{2}$ greater than the non-thermal line widths. However, other studies have used different factors. To investigate this discrepancy, we...
The purpose of our study is to deepen our understanding of the turbulence that arises from the Rayleigh Taylor Instability and leads to the formation and evolution of prominence. Quiescent prominence formed in the solar corona are cool and dense condensates comprising of varied dynamics of physical processes and scales. It is dominated by the vertical motion of flows in the upper atmosphere...
Alfvén waves have proven to be important in a range of physical systems due to their ability to transport non-thermal energy over long distances in a magnetised plasma. This property is of specific interest in solar physics where the extreme heating of the atmosphere of the Sun remains unexplained. In an inhomogeneous plasma like a flux tube in the solar atmosphere, they manifest as...
