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 ...

Evidence for small halos in grand design spiral galaxies
The Astrophysical Journal, 1990 Les courbes de rotation de 41 galaxies spirales de differents types sont comparees. Il est montre que les galaxies ayant deux bras longs et symetriques tendent a avoir des courbes de rotation exterieures tombantes alors que les galaxies ayant des bras multiples ou des bras floconneux courts ont plutot des courbes de rotation presques plates ou s ...

Environment Dependence of Disk Morphology of Spiral Galaxies [PDF]
, 2014 We analyze the dependence of disk morphology (arm class, Hubble type, bar type) of nearby spiral galaxies on the galaxy environment by using local background density ($\Sigma_{n}$), projected distance ($r_{p}$), and tidal index ($TI$) as measures of the ...

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-

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

Kinematics of the SN Refsdal host revealed by MUSE: a regularly rotating spiral galaxy at z ≃ 1.5 [PDF]
, 2018 We use Multi Unit Spectroscopic Explorer (MUSE) observations of the galaxy cluster MACS J1149.5+2223 to explore the kinematics of the grand-design spiral galaxy (Sp1149) hosting the supernova 'Refsdal'.

On the relative frequency of flocculent and grand design spiral structures in barred galaxies
The Astrophysical Journal, 1989 The bars in late-type spiral galaxies (SBbc to SBm and SABbc to SABm) show little correlation with grand design spiral structure, unlike the bars in early-type galaxies. This is further evidence for two different types of bars in the SB morphological class, and two different types of ovals in the SAB class.

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.
