Description
We present a kinematical study of 29 spiral galaxies included in the
Spitzer Survey of Stellar Structure in Galaxies, using Hα
Fabry-Perot (FP) data obtained with the Galaxy Hα Fabry-Perot
System instrument at the William Herschel Telescope in La Palma,
complemented with images in the R band and in Hα. The primary goal
is to study the evolution and properties of the main structural
components of galaxies through the kinematical analysis of the FP data,
complemented with studies of morphology, star formation and mass
distribution. In this paper we describe how the FP data have been
obtained, processed and analysed. We present the resulting moment maps,
rotation curves, velocity model maps and residual maps. Images are
available in FITS format through the NASA/IPAC Extragalactic Database
and the Centre de Données Stellaires. With these data products we
study the non-circular motions, in particular those found along the bars
and spiral arms. The data indicate that the amplitude of the
non-circular motions created by the bar does not correlate with the bar
strength indicators. The amplitude of those non-circular motions in the
spiral arms does not correlate with either arm class or star formation
rate along the spiral arms. This implies that the presence and the
magnitude of the streaming motions in the arms is a local phenomenon.

Numerical Astrophysics: Galaxy Formation and Evolution
How galaxies formed and evolved through cosmic time is one of the key questions of modern astronomy and astrophysics. Cosmological time- and length-scales are so large that the evolution of individual galaxies cannot be directly observed. Only through numerical simulations can one follow the emergence of cosmic structures within the current
