A multiwavelength study of spiral structure in galaxies. II. Spiral arms in deep optical observations [PDF]
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.

Evidence for small halos in grand design spiral galaxies
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 ...

Synthetic HI observations of a simulated spiral galaxy [PDF]
Using the Torus radiative transfer code we produce synthetic observations of the 21 cm neutral hydrogen line from an SPH simulation of a spiral galaxy. The SPH representation of the galaxy is mapped onto an AMR grid, and a ray tracing method is used to ...

J1649+2635: A Grand-Design Spiral with a Large Double-Lobed Radio Source [PDF]
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]
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 ...

A high resolution CO map of the inner region of M51 [PDF]
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.

Dawes Review 4: Spiral Structures in Disc Galaxies [PDF]
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]
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]
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'.
