Spiral structure in nearby galaxies I. Sample, data analysis, and overview of results
Monthly Notices of the Royal Astronomical Society, 2011 This paper, the first of two, introduces an observational study of spiral structure in galaxies chosen from the SINGS survey. Near infrared (NIR) and optical data are used to produce mass surface density maps, and from these the morphology of the disc is

On the plausible origins of the spiral character of galaxies
Open Astronomy, 2021 We here-in demonstrate that the proposed hitherto unknown gravitomagnetic dark-force that hypothetically explains the Flat Rotation Curves of Spiral Galaxies — this same force, explains very well, the logarithmic and as-well, the barred spiral shapes of ...

A photometrically and spectroscopically confirmed population of passive spiral galaxies [PDF]
, 2016 We have identified a population of passive spiral galaxies from photometry and integral field spectroscopy. We selected z < 0.035 spiral galaxies that have WISE colours consistent with little mid-infrared emission from warm dust.

Angular Momentum across the Hubble sequence from the CALIFA survey [PDF]
, 2014 We investigate the stellar angular momentum of galaxies across the Hubble sequence from the CALIFA survey. The distribution of CALIFA elliptical and lenticular galaxies in the $\lambda_{\rm Re}-\epsilon_{\rm e}$ diagram is consistent with that shown by ...

Symposium - International Astronomical Union, 1970 We point out some properties of barred spiral galaxies which are important for the theory of their formation and spiral structure, and describe some theoretical work on the dynamics of these systems.

A Comparison of the Simulations and Observations for a Nearby Spiral Arm
Frontiers in Astronomy and Space Sciences, 2021 The analysis is focused on the ability of galactic open clusters to trace the spiral arms, based on the recent data releases from Gaia. For this, a simple 1D description of the motion of spiral arms and clusters is introduced.

The Astrophysical Journal Letters, 2022 Mergers are thought to be a fundamental channel for galaxy growth, perturbing the gas dynamics and the magnetic fields ( B -fields) in the interstellar medium (ISM).
