Abstract
Various problems concerning the origin and evolution of spiral arms in galaxies are still remain unsettled. Also, only few studies are devoted to the parameters of the spiral structure in distant galaxies. To investigate this, we have performed decomposition with spiral arms of 138 distant galaxies from COSMOS and CEERS surveys, located at redshift 0.1 < z < 2.2 (up to 10.5 Gyr ago). For all 9 galaxies from CEERS, multi-band images are utilized. As a result, different parameters dependence on redshift and wavelength are studied. In particular, we confirm that pitch angle of spiral arms increases with redshift. For the spiral arm width, we find relationship with redshift, but this value depends much stronger on wavelength. A
