Grand Design versus Multiarmed Spiral Galaxies: Dependence on Galaxy Structure

open access: yesThe Astronomical Journal
We developed an algorithm to use Galaxy Zoo 3D spiral arm masks produced by citizen scientist volunteers to semiautomatically classify spiral galaxies as either multiarmed or grand design spirals. Our final sample consists of 299 multiarmed and 245 grand

Flocculent and grand design spiral galaxies in groups - Time scales for the persistence of grand design spiral structures

open access: yesAstrophysical Journal, 1983
Spiral arm classifications were made for 261 low-inclination galaxies in groups listed by Huchra and Geller. The fractional occurrence of grand design spiral structure in nonbarred galaxies was found to increase from approx.0.1 to approx.0.6 and then level off as the group crossing rate or galaxy collision rate in a group increases.

THE PdBI ARCSECOND WHIRLPOOL SURVEY (PAWS). I. A CLOUD-SCALE/MULTI-WAVELENGTH VIEW OF THE INTERSTELLAR MEDIUM IN A GRAND-DESIGN SPIRAL GALAXY [PDF]

open access: yesAstrophysical Journal, 2013
The PdBI (Plateau de Bure Interferometer) Arcsecond Whirlpool Survey (PAWS) has mapped the molecular gas in the central ~9kpc of M51 in its 12CO(1-0) line emission at cloud-scale resolution of ~40pc using both IRAM telescopes. We utilize this dataset to quantitatively characterize the relation of molecular gas (or CO emission) to other tracers of the ...

Blue and near-infrared surface photometry of spiral structure in 34 nonbarred grand design and flocculent galaxies

open access: yesAstrophysical Journal, Supplement Series, 1984
On a examine les profils radiaux du disque et la structure des bras spiraux des 34 galaxies. On donne les profils azimutaux et les diagrammes couleur-amplitude des bras spiraux. On discute des modeles d'evolution de la couleur. Ces modeles sont utilises pour determiner l'amplitude des spirales de densite stellaire sous jacentes et le renforcement ...

A grand-design spiral galaxy 1.5 billion years after the Big Bang with JWST

open access: yesAstronomy and Astrophysics
We report the discovery of Alaknanda, a large (∼10 kpc diameter), massive (log( M ⋆ / M ⊙ )∼10.2), candidate grand-design spiral galaxy with photometric redshift z phot

A Cloud-Scale View of the Molecular Gas Disk in the Whirlpool Galaxy and Beyond [PDF]

open access: yesEPJ Web of Conferences, 2022
The nearby galaxy M51 (also known as the Whirlpool galaxy) hosts an iconic grand-design spiral pattern and both IRAM facilities conducted the first cloud-scale (∼50 pc resolution) survey of the molecular gas reservoir across a the disk of a massive star ...
