Towards a more realistic population of bright spiral galaxies in cosmological simulations [PDF]
, 2013 We present an update to the multiphase SPH galaxy formation code by Scannapieco et al. We include a more elaborate treatment of the production of metals, cooling rates based on individual element abundances, and a scheme for the turbulent diffusion of ...

M101: The Pinwheel Galaxy [PDF]
, 2006 This Hubble Space Telescope image of M101 showcases a spiral galaxy's well-known features. The text describes the features that are common to all spiral galaxies.

The morphological dependent Tully-Fisher relation of spiral galaxies
, 2009 The Tully-Fisher relation of spiral galaxies shows notable dependence on morphological types, with earlier type spirals having systematically lower luminosity at fixed maximum rotation velocity $V_{max}$.

Gravitational torques in spiral galaxies: gas accretion as a driving mechanism of galactic evolution [PDF]
, 2002 The distribution of gravitational torques and bar strengths in the local Universe is derived from a detailed study of 163 galaxies observed in the near-infrared. The results are compared with numerical models for spiral galaxy evolution. It is found that

The collective origin of spiral structures in disk galaxies
EPJ Web of Conferences, 2012 After almost fifty years the origin of spiral arms in disk galaxies remains one of the major unsolved problems in astrophysics. Recent attempts have indicated that substructures in the dark matter halos of galaxies could induce spiral patterns in disks ...

Pitch angle variations in spiral galaxies [PDF]
, 2013 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 Digital Sky Survey.

Decreased Frequency of Strong Bars in S0 Galaxies: Evidence for Secular Evolution?
, 2010 Using data from the Near-Infrared S0 Survey (NIRS0S) of nearby, early-type galaxies, we examine the distribution of bar strengths in S0 galaxies as compared to S0/a and Sa galaxies, and as compared to previously published bar strength data for Ohio State

Color Differences between Clockwise and Counterclockwise Spiral Galaxies [PDF]
, 2013 While spiral galaxies observed from Earth clearly seem to spin in different directions, little is yet known about other differences between galaxies that spin clockwise and galaxies that spin counterclockwise.
