Statistical Investigation of Wave Propagation in the Quiet-Sun Using IRIS Spectroscopic Observations
The Astrophysical JournalIn this analysis, we use spectroscopic observations of the quiet Sun made by the IRIS instrument and investigate wave propagation. We analyze various spectral lines formed in different atmospheric layers, such as the photosphere, chromosphere, and ...

Evolutionary Tracks Of Quiet-Sun Magnetic Features
, 2015 This thesis presents a study of quiet-Sun magnetic features in the solar photosphere. Magnetic fields in the quiet Sun organize on small spatial scales, evolve very rapidly, and produce weak polarization signals. With these properties their observation requires high spatial and temporal resolution together with sensitive and accurate polarimetric ...

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops
The Astrophysical JournalDecayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (
