Using numerical simulations of the magnetised solar photosphere carried out
with the radiative magneto-hydrodynamic code, MURaM, and detailed
spectro-polarimetric diagnostics of the simulated photospheric 6302A FeI line,
spectro-polarimetric signatures of Alfven waves in magnetised intergranular
lanes of the simulated solar photosphere were analysed at different positions
at the solar disk. The torsional Alfven waves in the intergranular lanes are
horizontal plasma motions, which do not have a thermal perturbation
counterpart. We find signatures of Alfven waves as small-scale line profile
Doppler shifts and Stokes-V area asymmetry enhancements in the simulated
off-disk centre observations. These photospheric features disappear when the
simulated observations are degraded with a telescope PSF similar to the one of
Hinode. We analyse the possibilities for direct observations and confirmation
of Alfven wave presence in the solar photosphere.Comment: 6 pages, 3 figures, accepted to PAS
