  1. Turbulent black hole coronae can produce observed X-ray spectra
    Simulations show turbulent black hole coronae generate two-temperature plasmas with extended nonthermal ion distributions while producing observed X-ray spectra.
  2. Time-resolved X-ray probes track heating and ionization in solid-density plasma
    Sub-picosecond X-ray spectroscopy and multi-scale simulations reveal spatiotemporal heating and ionization dynamics in laser-driven plasmas, with implications for fusion energy models.
  3. Trace ethylene boosts nitrogen GC-MS sensitivity
    Adding trace ethylene to nitrogen carrier gas in GC-MS increases sensitivity 20-fold while maintaining 70 eV electron-ionization spectral patterns compatible with existing reference libraries.
  4. DM Tau disk shows non-thermal line broadening
    Bayesian analysis of molecular line observations confirms nonthermal broadening of 0.4 sound speeds in the DM Tau protoplanetary disk, providing evidence for turbulence.
  5. Supermassive stars may match JWST little red dot spectra
    Supermassive star models reproduce spectral signatures of JWST little red dots, suggesting these compact sources may be progenitors of the first supermassive black holes.
  6. RUBIES confirms many massive quiescent galaxies at 2 < z < 5
    Spectroscopic observations confirm that massive quiescent galaxies were surprisingly common at redshifts 2-5, challenging galaxy formation simulations.
  7. Muon-induced neutron spectra show possible high-multiplicity anomalies in lead
    Analysis of muon-induced neutron emission from lead targets reveals systematic deviations from standard power-law modeling, with evidence of structure in high-multiplicity events independent of depth.
