Pitch angle variations in spiral galaxies
S. S. Savchenko, V. P. Reshetnikov
We present a detailed photometric study and measurements of spiral arm pitch angles for a sample of 50 non-barred or weakly barred grand-design spiral galaxies selected from Sloan…

Pitch angles of distant spiral galaxies
S. S. Savchenko, V. P. Reshetnikov
We have studied the pitch angles of spiral arms for 31 distant galaxies at z~0.7 from three Hubble Deep Fields (HDF-N, HDF-S, HUDF). Using the pitch angle - rotation velocity relat…
