Scale and Time Dependence of Alfvénicity in the Solar Wind as Observed by {\it Parker Solar Probe}
Panisara Thepthong, Peera Pongkitiwanichakul, David Ruffolo +4
Alfvénicity is a well-known property, common in the solar wind, characterized by a high correlation between magnetic and velocity fluctuations. Data from the Parker Solar Probe (PS…
Statistics of Turbulence in the Solar Wind. I. What is the Reynolds Number of the Solar Wind?
Daniel Wrench, Tulasi N. Parashar, Sean Oughton +2
The Reynolds number, Re, is an important quantity for describing a turbulent flow. It tells us about the bandwidth over which energy can cascade from large scales to smaller ones,…
Scale Filtering Analysis of Kinetic Reconnection and its Associated Turbulence
Subash Adhikari, Yan Yang, William H. Matthaeus +3
Previously, using an incompressible von Kármán-Howarth formalism, the behavior of cross-scale energy transfer in magnetic reconnection and turbulence was found to be essentially id…
Power spectrum estimation methods on intracluster medium surface brightness fluctuations
Mark Bishop, Yvette Perrott, Tulasi Parashar +1
Accurate estimation of galaxy cluster masses is a central problem in cosmology. Turbulence is believed to introduce significant deviations from the hydrostatic mass estimates. Esti…
Probing the evolution of galaxy clusters using SZ effect and non-thermal emission: first results from A1413
Mohini Pachchigar, Yvette Perrott, Tulasi Parashar
Mass is the most fundamental property of galaxy clusters. However, measuring it is still a challenge. Calibrating mass from intracluster medium observables such as the Sunyaev-Zel'…
Effective Viscosity, Resistivity, and Reynolds Number in Weakly Collisional Plasma Turbulence
Yan Yang, William H. Matthaeus, Sean Oughton +6
We examine dissipation and energy conversion in weakly collisional plasma turbulence, employing in situ observations from the Magnetospheric Multiscale (MMS) mission and kinetic Pa…
Statistics of Pressure Fluctuations in Turbulent Kinetic Plasmas
Subash Adhikari, William H. Matthaeus, Tulasi N. Parashar +2
In this study we explore the statistics of pressure fluctuations in kinetic collisionless turbulence. A 2.5D kinetic particle-in-cell (PIC) simulation of decaying turbulence is use…
Effect of a guide field on the turbulence like properties of magnetic reconnection
Subash Adhikari, Michael A. Shay, Tulasi N. Parashar +4
The effect of an external guide field on the turbulence-like properties of magnetic reconnection is studied using five different 2.5D kinetic particle-in-cell (PIC) simulations. Th…
