Analysis of eigenvalue clustering leads to optimal scaling in numerical radiative transfer
Pietro Benedusi, Simone Riva, Luca Belluzzi +1
We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, i.e. anisotropic (dipole) scattering with parti…

3D radiative transfer modeling of scattering polarization with partial frequency redistribution I. Verification and disk-center results for the solar Ca I 4227 Ã 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…

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
Fabio Riva, Gioele Janett, Luca Belluzzi +6
Aims. The main goal of this paper is to present an accurate and efficient numerical strategy for solving the radiative transfer problem for polarised radiation in strong resonance…
