J1649+2635: A Grand-Design Spiral with a Large Double-Lobed Radio Source [PDF]
, 2014 We report the discovery of a grand-design spiral galaxy associated with a double-lobed radio source. J1649+2635 (z = 0.0545) is a red spiral galaxy with a prominent bulge that it is associated with a L(1.4GHz) is approximately 10(exp24) W Hz(exp1) double-

GRAND DESIGN AND FLOCCULENT SPIRALS IN THESPITZERSURVEY OF STELLAR STRUCTURE IN GALAXIES (S4G) [PDF]
The Astrophysical Journal, 2011 Spiral arm properties of 46 galaxies in the Spitzer Survey of Stellar Structure in Galaxies (S4G) were measured at 3.6mu, where extinction is small and the old stars dominate. The sample includes flocculent, multiple arm, and grand design types with a wide range of Hubble and bar types.

Simulations of Normal Spiral Galaxies [PDF]
, 2003 Results are presented of numerical simulations of normal isolated late type spiral galaxies. Specifically the galaxy NGC 628 is used as a template. The method employs a TREESPH code including stellar particles, gas particles, cooling and heating of the ...

Dawes Review 4: Spiral Structures in Disc Galaxies [PDF]
, 2014 The majority of astrophysics involves the study of spiral galaxies, and stars and planets within them, but how spiral arms in galaxies form and evolve is still a fundamental problem. Major progress in this field was made primarily in the 1960s, and early

Simulations of dual morphology in spiral galaxies [PDF]
, 2002 Gas and stars in spiral galaxies are modelled with the DUAL code, using hydrodynamic and N-body techniques. The simulations reveal morphological differences mirroring the dual morphologies seen in B and K' band observations of many spiral galaxies.

Clues to the formation of spiral structure in M51 from the ages and locations of star clusters [PDF]
, 2017 We determine the spatial distributions of star clusters at different ages in the grand-design spiral galaxy M51 using a new catalog based on multi-band images taken with the Hubble Space Telescope (HST). These distributions, when compared with the spiral
