A multiwavelength study of spiral structure in galaxies. II. Spiral arms in deep optical observations [PDF]
Monthly notices of the Royal Astronomical Society, 2023 In this paper, we look to analyse the spiral features of grand-design, multiarmed, and flocculent spiral galaxies using deep optical imaging from DESI Legacy Imaging Surveys.

Uncovering Spiral Structure in Flocculent Galaxies [PDF]
, 1996 We present K'(2.1 micron) observations of four nearby flocculent spirals, which clearly show low-level spiral structure and suggest that kiloparsec-scale spiral structure is more prevalent in flocculent spirals than previously supposed.

A high resolution CO map of the inner region of M51 [PDF]
, 1998 M51, the Whirlpool Galaxy, at a distance of ≈ 9,6 Mpc and a systemic velocity of 465 km s^(−1), is the closest “Grand Design” spiral galaxy. Its low inclination (20°) makes it an excellent target for structural studies, e.g.

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-

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 ...

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.

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

The Carnegie-Irvine Galaxy Survey. VI. Quantifying Spiral Structure [PDF]
Astrophysical Journal, 2018 The Carnegie-Irvine Galaxy Survey provides high-quality broadband optical images of a large sample of nearby galaxies for detailed study of their structure. To probe the physical nature and possible cosmological evolution of spiral arms, a common feature

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
