Relativistic magnetically dominated turbulence is an efficient engine for particle acceleration in a collisionless plasma. Ultrarelativistic particles accelerated by interactions with turbulent fluctuations form nonthermal powerlaw distribution functions in the momentum (or energy) space,
We present a phenomenological and numerical study of strong Alfvénic turbulence in a magnetically dominated collisionless relativistic plasma with a strong background magnetic field. In contrast with the nonrelativistic case, the energy in such turbulence is contained in magnetic and electric fluctuations. We argue that such turbulence is analogous to turbulence in a strongly magnetized nonrelativistic plasma in the regime of broken quasineutrality. Our 2D particleincell numerical simulations of turbulence in a relativistic pair plasma find that the spectrum of the total energy has the scaling

Abstract f (γ )d γ ∝γ ^{−α}d γ , whereγ is the Lorenz factor. We argue that in addition to exhibiting nonGaussian distributions over energies, particles energized by relativistic turbulence also become highly intermittent in space. Based on particleincell numerical simulations and phenomenological modeling, we propose that the bulk plasma density has lognormal statistics, while the density of the accelerated particles,n , has a powerlaw distribution function, . We argue that the scaling exponents are related as $P(n)\mathit{dn}\phantom{\rule{0.25em}{0ex}}\propto \phantom{\rule{0.25em}{0ex}}{n}^{\beta}\mathit{dn}$β ≈α + 1, which is broadly consistent with numerical simulations. Nonspacefilling, intermittent distributions of plasma density and energy fluctuations may have implications for plasma heating and for radiation produced by relativistic turbulence. 
Abstract We present analysis of 17,043 proton kineticscale current sheets (CSs) collected over 124 days of Wind spacecraft measurements in the solar wind at 11 samples s^{−1}magnetic field resolution. The CSs have thickness,
λ, from a few tens to one thousand kilometers with typical values around 100 km, or within about 0.1–10λ _{p}in terms of local proton inertial length,λ _{p}. We found that the current density is larger for smallerscale CSs,J _{0}≈ 6 nAm^{−2}· (λ /100 km)^{−0.56}, but does not statistically exceed a critical value,J _{A}, corresponding to the drift between ions and electrons of local Alvén speed. The observed trend holds in normalized units: . The CSs are statistically forcefree with magnetic shear angle correlated with CS spatial scale: ${J}_{0}/{J}_{A}\approx 0.17\xb7{(\lambda /{\lambda}_{p})}^{0.51}$ . The observed correlations are consistent with local turbulence being the source of proton kineticscale CSs in the solar wind, while the mechanisms limiting the current density remain to be understood. $\mathrm{\Delta}\theta \approx 19\xb0\xb7{(\lambda /{\lambda}_{p})}^{0.5}$ 
Abstract We perform particleincell simulations to elucidate the microphysics of relativistic weakly magnetized shocks loaded with electronpositron pairs. Various external magnetizations
σ ≲ 10^{−4}and pairloading factorsZ _{±}≲ 10 are studied, whereZ _{±}is the number of loaded electrons and positrons per ion. We find the following: (1) The shock becomes mediated by the ion Larmor gyration in the mean field whenσ exceeds a critical valueσ _{L}that decreases withZ _{±}. Atσ ≲σ _{L}the shock is mediated by particle scattering in the selfgenerated microturbulent fields, the strength and scale of which decrease withZ _{±}, leading to lowerσ _{L}. (2) The energy fraction carried by the postshock pairs is robustly in the range between 20% and 50% of the upstream ion energy. The mean energy per postshock electron scales as . (3) Pair loading suppresses nonthermal ion acceleration at magnetizations as low as ${\overline{E}}_{\mathrm{e}}\propto {\left({Z}_{\pm}+1\right)}^{1}$σ ≈ 5 × 10^{−6}. The ions then become essentially thermal with mean energy , while electrons form a nonthermal tail, extending from ${\overline{E}}_{\mathrm{i}}$ to $E\sim {\left({Z}_{\pm}+1\right)}^{1}{\overline{E}}_{\mathrm{i}}$ . When ${\overline{E}}_{\mathrm{i}}$σ = 0, particle acceleration is enhanced by the formation of intense magnetic cavities that populate the precursor during the late stages of shock evolution.

Abstract The Parker Solar Probe (PSP) entered a region of subAlfvénic solar wind during encounter 8, and we present the first detailed analysis of lowfrequency turbulence properties in this novel region. The magnetic field and flow velocity vectors were highly aligned during this interval. By constructing spectrograms of the normalized magnetic helicity, crosshelicity, and residual energy, we find that PSP observed primarily Alfvénic fluctuations, a consequence of the highly fieldaligned flow that renders quasi2D fluctuations unobservable to PSP. We extend Taylor’s hypothesis to sub and superAlfvénic flows. Spectra for the fluctuating forward and backward Elsässer variables (
^{±}, respectively) are presented, showing thatz ^{+}modes dominatez ^{−}by an order of magnitude or more, and thez ^{+}spectrum is a power law in frequency (parallel wavenumber)z f ^{−3/2}( ) compared to the convex ${k}_{\parallel}^{3/2}$ ^{−}spectrum withz f ^{−3/2}( ) at low frequencies, flattening around a transition frequency (at which the nonlinear and Alfvén timescales are balanced) to ${k}_{\parallel}^{3/2}$f ^{−1.25}at higher frequencies. The observed spectra are well fitted using a spectral theory for nearly incompressible magnetohydrodynamics assuming a wavenumber anisotropy , that the ${k}_{\perp}\sim {k}_{\parallel}^{3/4}$ ^{+}fluctuations experience primarily nonlinear interactions, and that the minorityz ^{−}fluctuations experience both nonlinear and Alfvénic interactions withz ^{+}fluctuations. The density spectrum is a powermore »z 
Abstract We use ALMA observations of CO(2–1) in 13 massive (
M _{*}≳ 10^{11}M _{⊙}) poststarburst galaxies atz ∼ 0.6 to constrain the molecular gas content in galaxies shortly after they quench their major starforming episode. The poststarburst galaxies in this study are selected from the Sloan Digital Sky Survey spectroscopic samples (Data Release 14) based on their spectral shapes, as part of the Studying QUenching at Intermediatez Galaxies: Gas, angu momentum, and Evolution ( $$\overrightarrow{L}\mathrm{ar}$$ ) program. Early results showed that two poststarburst galaxies host large H_{2}reservoirs despite their low inferred star formation rates (SFRs). Here we expand this analysis to a larger statistical sample of 13 galaxies. Six of the primary targets (45%) are detected, with $\mathit{SQuIGG}\stackrel{\u20d7}{L}E$ ${M}_{{\mathrm{H}}_{2}}\gtrsim {10}^{9}$M _{⊙}. Given their high stellar masses, this mass limit corresponds to an average gas fraction of or ∼14% using lower stellar masses estimates derived from analytic, exponentially declining star formation histories. The gas fraction correlates with the $\u3008{f}_{{\mathrm{H}}_{2}}\equiv {M}_{{\mathrm{H}}_{2}}/{M}_{*}\u3009\sim 7\%$D _{n}4000 spectral index, suggesting that the cold gas reservoirs decrease with time since burst, as found in local K+A galaxies. Star formation histories derived from flexible stellar population synthesis modeling support thismore »
