Limb-brightened Jet in M87 from Anisotropic Nonthermal Electrons
The Astrophysical JournalVery long baseline interferometry observations reveal that relativistic jets like the one in M87 have a limb-brightened, double-edged structure. Analytic and numerical models struggle to reproduce this limb-brightening.

Universal thermodynamic topological classes of rotating black holes
Physics Letters BIn a recent study, Wei et al. (2024) [96] proposed a universal classification scheme that interprets black hole solutions, including the four-dimensional Schwarzschild, Reissner-Nordström (RN), Schwarzschild-AdS, and RN-AdS black hole solutions, as ...

Advanced Materials, EarlyView.Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

Computing binary black hole merger waveforms using openGR [PDF]
, 2012 textOne of the most important predictions of General Relativity, Einstein’s theory of gravity, is the existence of gravitational radiation. The strongest source of such radiation is expected to come from the merging of black holes.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics
Advanced Materials, EarlyView.Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...
