Hybrid Kinetic-MHD Simulations of Drift-Orbit Effects on the Stability and Non-Linear Dynamics of Runaway Electron Beams
Shi-Jie Liu, Hao-Wei Zhang, Hannes Bergstroem +2
During tokamak disruptions, the Ohmic current may be replaced by a non-inductive runaway electron (RE) current, affecting resistive stability. Previous studies suggest that, in the…
Compact near infrared sources in the center of the extraordinary galaxy IC 860
J. S. Gallagher, L. Schisgal, G. C. Privon +7
Hubble Space Telescope (HST) images are used to study the structure of the central regions of the luminous infrared galaxy (LIRG) IC 860. IC 860 is of special interest as a system…
A search for the first galaxies across deg of JWST imaging: new evidence for a rapid decline in star-formation activity at
D. J. McLeod, J. S. Dunlop, R. J. McLure +20
We present a new determination of the evolving galaxy UV luminosity function (LF) over the extreme redshift range , based on a wide-area search of 0.6 deg of JW…
Physics-Constrained Neural Closure for Lattice Boltzmann Large-Eddy Simulation
Muhammad Idrees Khan, Sauro Succi, Hua-Dong Yao +1
We present a physics-constrained, data-driven subgrid-scale (SGS) stress closure for large-eddy simulation (LES) in the lattice Boltzmann method (LBM). Trained on filtered-downsamp…
Detection of CO ice in the planetary nebula NGC 6302
Charmi Bhatt, Simon W. Cao, Jan Cami +20
Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…
A sub-ppm upper limit on the cosmological variations of the fine structure constant alpha
S. Muller, A. Beelen, M. Guelin +9
Absorption spectroscopy toward high-redshift quasars provides strong constraints on the putative variation of fundamental constants of physics on cosmological time scales. The subm…
