Noise in the Heliosphere: A Target for PUNCH Science

Jiaming Wang, William H. Matthaeus, Rohit Chhiber +4

We present a broad review of 1/f noise observations in the heliosphere, and discuss and complement the theoretical background of generic 1/f models as relevant to NASA's PUNCH miss…

Spatio-Temporal Energy Cascade in Three-Dimensional Magnetohydrodynamic Turbulence

Giuseppe Arrò, Hui Li, William H. Matthaeus

We present a new scale decomposition method to investigate turbulence in wavenumber-frequency space. Using 3D magnetohydrodynamic turbulence simulations, we show that magnetic fluc…

Observed Fluctuation Enhancement and Departure from WKB Theory in Sub-Alfvénic Solar Wind

David Ruffolo, Panisara Thepthong, Peera Pongkitiwanichakul +12

Using Parker Solar Probe data from orbits 8 through 17, we examine fluctuation amplitudes throughout the critical region where the solar wind flow speed approaches and then exceeds…

Evaluation of scale-dependent kurtosis with HelioSwarm

Francesco Pecora, Francesco Pucci, Francesco Malara +4

Plasma turbulence involves complex, nonlinear interactions of electromagnetic fields and charged particles across multiple scales. Studying these phenomena in space plasmas, like t…

The Alfvén Transition Zone observed by the Parker Solar Probe in Young Solar Wind -- Global Properties and Model Comparisons

Rohit Chhiber, Francesco Pecora, Arcadi V Usmanov +6

The transition from subAlfvénic to superAlfvénic flow in the solar atmosphere is examined by means of Parker Solar Probe (PSP) measurements during solar encounters 8 to 14. Aroun…

Anisotropy of Density Fluctuations in the Solar Wind at 1 au

Jiaming Wang, Rohit Chhiber, Sohom Roy +6

A well-known property of solar wind plasma turbulence is the observed anisotropy of the autocorrelations, or equivalently the spectra, of velocity and magnetic field fluctuations.…
