Turbulent black hole coronae can produce observed X-ray spectra
—
in AstrophysicsSimulations show turbulent black hole coronae generate two-temperature plasmas with extended nonthermal ion distributions while producing observed X-ray spectra.
DM Tau disk shows non-thermal line broadening
—
in AstrophysicsBayesian analysis of molecular line observations confirms nonthermal broadening of 0.4 sound speeds in the DM Tau protoplanetary disk, providing evidence for turbulence.
Relativistic effects change synchrotron shock modeling accuracy
—
in AstrophysicsNumerical model reveals that simplified approximations for synchrotron emission from relativistic shocks can be inaccurate by over an order of magnitude, biasing inferred properties of transients.
TransFit-CSM models interaction-powered transients with consistent shock diffusion
Fast, physically consistent framework for modeling interaction-powered transients through self-consistent ejecta-CSM shock and radiative diffusion coupling.
High-altitude ice clouds show daytime cooling and nighttime warming
—
A rapid satellite-based methodology quantifies radiative forcing from high-altitude ice clouds and contrails using geostationary observations with 15% accuracy.
Dust layer weakens low-level cloud increase over the North Atlantic
Study quantifies how free-tropospheric Saharan dust over the North Atlantic modulates low-level cloud cover via longwave-induced cloud-top warming that counteracts shortwave-driven cloud enhancement.
