Stream-aligned Magnetohydrodynamics for Solar Wind Simulations [PDF]
The Astrophysical Journal, 2021 Abstract We present a reduced magnetohydrodynamic (MHD) mathematical model describing the dynamical behavior of highly conducting plasmas with frozen-in magnetic fields, constrained by the assumption that there exists a frame of reference, where the magnetic field vector,

Robust Field-level Likelihood-free Inference with Galaxies
The Astrophysical Journal, 2023 We train graph neural networks to perform field-level likelihood-free inference using galaxy catalogs from state-of-the-art hydrodynamic simulations of the CAMELS project.

Simulations of Incompressible Magnetohydrodynamic Turbulence [PDF]
The Astrophysical Journal, 2001 We simulate incompressible MHD turbulence using a pseudospectral code. Our major conclusions are: (1) MHD turbulence is most conveniently described in terms of counterpropagating shear Alfven and slow waves. Shear Alfven waves control the cascade dynamics. Slow waves play a passive role and adopt the spectrum set by the shear Alfven waves.

Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]
, 2014 Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

Striped Jets in Post–Neutron Star Merger Systems
The Astrophysical Journal, 2023 Models invoking magnetic reconnection as the particle acceleration mechanism within relativistic jets often adopt a gradual energy dissipation profile within the jet. However, such a profile has yet to be reproduced in first-principles simulations.

The Formation of Star-forming Disks in the TNG50 Simulation
The Astrophysical Journal, 2023 We investigate the disk formation process in the TNG50 simulation, examining the profiles of SFR surface density (Σ _SFR ), gas inflow and outflow, and the evolution of the angular momentum of inflowing gas particles.

, 2020 The algorithm used to build the computer simulations was previously described elsewhere (Beltrame & Hughson, 2017a, 2017c). The simulated aVO2 time series response to an CWR and PRBS protocol (with a work rate variation between 25 and 100 watts) were ...

Hydrodynamical simulations of massive stars collisions [PDF]
, 2023 openSince the detection of gravitational waves traveling through our universe, a new field of astrophysics has opened up, and with it many hypotheses and theoretical predictions have been put to the test. This is the case of the pair-instability mass gap
