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.

The sequence of spiral arm classes: Observational signatures of persistent spiral density waves in grand-design galaxies [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractWe investigate how the properties of spiral arms relate to other fundamental galaxy properties. To this end, we use previously published measurements of those properties, and our own measurements of arm-interarm luminosity contrasts for a large sample of galaxies, using 3.6μm images from the Spitzer Survey of Stellar Structure in Galaxies ...

A grand-design spiral galaxy 1.5 billion years after the Big Bang with JWST [PDF]
Astronomy & AstrophysicsWe report the discovery of a large (∼10 kpc diameter), massive (łog(M_⋆/M_⊙)∼10.2), candidate grand-design spiral galaxy with photometric redshift z_ phot ∼4.05 in the UNCOVER and Medium band, Mega Science surveys with JWST. This is among the highest redshift spiral galaxies discovered with JWST.

PANORAMIC: Discovery of an ultra-massive grand-design spiral galaxy at z ∼ 5.2 [PDF]
Astronomy & AstrophysicsWe report the discovery of an ultra-massive grand-design red spiral galaxy, named Zhúlóng (Torch Dragon), at zphot = 5.2−0.2+0.3 in the JWST PANORAMIC survey; it is the most distant bulge+disk galaxy candidate with spiral arms known to date. Zhúlóng displays an extraordinary combination of properties: (1) a classical bulge centered in a large, face-on ...

Analyzing the cosmic architecture in the vicinity of Grand-design and Flocculent spiral galaxies with Local Geometric Index [PDF]
, 2023 We explore the environment of 351 grand-design and 541 flocculent spiral galaxies recently identified employing convolutional neural networks from the $17^{th}$ data release of Sloan Digital Sky Survey. We introduce a novel estimator called the Local Geometric Index to quantify the morphology of the local environment of these 892 spirals.

Gas and stellar spiral arms and their offsets in the grand-design spiral galaxy M51 [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 Theoretical studies on the response of interstellar gas to a gravitational potential disc with a quasi-stationary spiral arm pattern suggest that the gas experiences a sudden compression due to standing shock waves at spiral arms. This mechanism, called a galactic shock wave, predicts that gas spiral arms move from downstream to upstream of stellar ...
