3D radiative transfer modeling of scattering polarization with partial frequency redistribution I. Verification and disk-center results for the solar Ca I 4227 Å line
Pietro Benedusi, Simone Riva, Tanausú del Pino Alemán +6
Several strong solar resonance lines show observable linear scattering polarization signals, holding a great potential for investigating the magnetism of the outer solar atmosphere…
Adaptive Multidimensional Quadrature on Multi-GPU Systems
Melanie Tonarelli, Simone Riva, Pietro Benedusi +2
We introduce a distributed adaptive quadrature method that formulates multidimensional integration as a hierarchical domain decomposition problem on multi-GPU architectures. The in…
A numerical approach for modelling the polarisation signals of strong resonance lines with partial frequency redistribution. Numerical applications to two-term atoms and plane-parallel atmospheres
