We perform particleincell simulations to elucidate the microphysics of relativistic weakly magnetized shocks loaded with electronpositron pairs. Various external magnetizations
Ultrafast spectroscopies have become an important tool for elucidating the microscopic description and dynamical properties of quantum materials. In particular, by tracking the dynamics of nonthermal electrons, a material’s dominant scattering processes can be revealed. Here, we present a method for extracting the electronphonon coupling strength in the time domain, using time and angleresolved photoemission spectroscopy (TRARPES). This method is demonstrated in graphite, where we investigate the dynamics of photoinjected electrons at the

Abstract 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. Here, the maximum energy of the nonthermal ions and electrons keeps growing over the duration of the simulation. Alongside the simulations, we develop theoretical estimates consistent with the numerical results. Our findings have important implications for models of early gammaray burst afterglows. 
Abstract While it is well known that cosmic rays (CRs) can gain energy from turbulence via secondorder Fermi acceleration, how this energy transfer affects the turbulent cascade remains largely unexplored. Here, we show that damping and steepening of the compressive turbulent power spectrum are expected once the damping time
becomes comparable to the turbulent cascade time. Magnetohydrodynamic simulations of stirred compressive turbulence in a gasCR fluid with diffusive CR transport show clear imprints of CRinduced damping, saturating at ${t}_{\mathrm{damp}}\sim \rho {v}^{2}/{\stackrel{\u0307}{E}}_{\mathrm{CR}}\propto {E}_{\mathrm{CR}}^{1}$ , where ${\stackrel{\u0307}{E}}_{\mathrm{CR}}\sim \tilde{\u03f5}$ is the turbulent energy input rate. In that case, almost all of the energy in largescale motions is absorbed by CRs and does not cascade down to grid scale. Through a Hodge–Helmholtz decomposition, we confirm that purely compressive forcing can generate significant solenoidal motions, and we find preferential CR damping of the compressive component in simulations with diffusion and streaming, rendering smallscale turbulence largely solenoidal, with implications for thermal instability and proposed resonant scattering of $\tilde{\u03f5}$E ≳ 300 GeV CRs by fast modes. When CR transport is streaming dominated, CRs also damp largescale motions, with kinetic energy reduced by up to 1 order of magnitude in realisticE _{CR}∼E _{g}scenarios, but turbulence (with a reduced amplitude) still cascades down to small scales with the same power spectrum. Such largescale damping implies that turbulent velocities obtained from the observed velocity dispersion may significantly underestimate turbulent forcing rates, i.e., . $\tilde{\u03f5}\gg \rho {v}^{3}/L$ 
Abstract We present UV and/or optical observations and models of SN 2023ixf, a type II supernova (SN) located in Messier 101 at 6.9 Mpc. Early time (
flash ) spectroscopy of SN 2023ixf, obtained primarily at Lick Observatory, reveals emission lines of Hi , Hei/ii , Civ , and Niii/iv/v with a narrow core and broad, symmetric wings arising from the photoionization of dense, closein circumstellar material (CSM) located around the progenitor star prior to shock breakout. These electronscattering broadened line profiles persist for ∼8 days with respect to first light, at which time Doppler broadened the features from the fastest SN ejecta form, suggesting a reduction in CSM density atr ≳ 10^{15}cm. The early time light curve of SN 2023ixf shows peak absolute magnitudes (e.g.,M _{u}= −18.6 mag,M _{g}= −18.4 mag) that are ≳2 mag brighter than typical type II SNe, this photometric boost also being consistent with the shock power supplied from CSM interaction. Comparison of SN 2023ixf to a grid of lightcurve and multiepoch spectral models from the nonLTE radiative transfer codeCMFGEN and the radiationhydrodynamics codeHERACLES suggests dense, solarmetallicity CSM confined tor = (0.5–1) × 10^{15}cm, and a progenitor massloss rate of yr^{−1}. For the assumed progenitor wind velocity of $\stackrel{\u0307}{M}={10}^{2}\phantom{\rule{0.25em}{0ex}}{M}_{\odot}$v _{w}= 50 km s^{−1}, this corresponds to enhanced mass loss (i.e.,superwind phase) during the last ∼3–6 yr before explosion. 
Abstract Recently, room temperature superconductivity was measured in a carbonaceous sulfur hydride material whose identity remains unknown. Herein, firstprinciples calculations are performed to provide a chemical basis for structural candidates derived by doping H_{3}S with low levels of carbon. Pressure stabilizes unusual bonding configurations about the carbon atoms, which can be sixfold coordinated as CH_{6}entities within the cubic H_{3}S framework, or fourfold coordinated as methane intercalated into the HS lattice, with or without an additional hydrogen in the framework. The doping breaks degenerate bands, lowering the density of states at the Fermi level (
N _{F}), and localizing electrons in CH bonds. Low levels of CH_{4}doping do not increaseN _{F}to values as high as those calculated for H_{3}S, but they can yield a larger logarithmic average phonon frequency, and an electron–phonon coupling parameter comparable to that of$$Im\bar{3}m$$ $Im\overline{3}m$R 3m H_{3}S. The implications of carbon doping on the superconducting properties are discussed. 
Abstract Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies across many orders of magnitude in spatial and temporal scales, making this problem notoriously challenging to simulate. We use a multizone computational method based on the general relativistic magnetohydrodynamic (GRMHD) code KHARMA that allows us to span 7 orders of magnitude in spatial scale, to simulate accretion onto a nonspinning SMBH from an external medium with a Bondi radius of
R _{B}≈ 2 × 10^{5}GM _{•}/c ^{2}, whereM _{•}is the SMBH mass. For the classic idealized Bondi problem, spherical gas accretion without magnetic fields, our simulation results agree very well with the general relativistic analytic solution. Meanwhile, when the accreting gas is magnetized, the SMBH magnetosphere becomes saturated with a strong magnetic field. The density profile varies as ∼r ^{−1}rather thanr ^{−3/2}and the accretion rate is consequently suppressed by over 2 orders of magnitude below the Bondi rate $\stackrel{\u0307}{M}$ . We find continuous energy feedback from the accretion flow to the external medium at a level of ${\stackrel{\u0307}{M}}_{\mathrm{B}}$ . Energy transport across these widely disparate scales occurs via turbulent convection triggered by magnetic field reconnection near the SMBH. Thus, strong magnetic fields that accumulate on horizon scales transform the flow dynamics far from the SMBH and naturally explain observed extremely low accretion rates compared to the Bondi rate, as well as at least part of the energy feedback. $\sim {10}^{2}\stackrel{\u0307}{M}{c}^{2}\sim 5\phantom{\rule{0.15em}{0ex}}\times \phantom{\rule{0.15em}{0ex}}{10}^{5}{\stackrel{\u0307}{M}}_{\mathrm{B}}{c}^{2}$
