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

open access: yesMonthly 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.

Evidence for small halos in grand design spiral galaxies

open access: yesThe 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 ...

Synthetic HI observations of a simulated spiral galaxy [PDF]

open access: yes, 2010
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]

open access: yes, 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]

open access: yes, 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 ...

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

open access: yes, 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.

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

open access: yes, 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]

open access: yesAstrophysical 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]

open access: yes, 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'.
