NGC 5236's stars as tracers of arms and arm widths in spiral galaxies [PDF]
, 2022 Generally, identifying the spiral arms of a spiral galaxy is not a hard task. However, defining the main characteristics, width and length of those structure is not a common task. Previous studies have used different tracers: Star clusters, Massers, H$\alpha$. It was until recently that individual stars were used as tracers of spiral structures.

MOLECULAR DISTRIBUTION IN THE SPIRAL ARM OF M51 [PDF]
The Astrophysical Journal, 2016 ABSTRACT Molecular line images of 13CO, C18O, CN, CS, CH3OH, and HNCO are obtained toward the spiral arm of M51 at a resolution with the Combined Array for Research in Millimeter-wave Astronomy.

, 2022 The most important theory of the spiral arms of galaxies is the density wave theory based on the Lin-Shu dispersion relation. However, the density waves move with the group velocity towards the inner Lindblad resonance and tend to disappear. Various mechanisms to replenish the spiral waves have been proposed.

Catalog of observed tangents to the spiral arms in the Milky Way galaxy [PDF]
2014 Nov., Astrophysical Journal Supplement Series, vol. 215, art.
1, pp.1-9, 2014 From the sun's location in the Galactic disk, one can use different arm tracers (CO, HII, thermal or ionized or relativistic electrons, masers, cold or hot dust, etc) to locate a tangent to each spiral arm in the disk of the Milky Way galaxy. We present a Master catalog of the astronomically observed tangents to the Galaxy's spiral arms, using ...

Planet-driven spiral arms in protoplanetary disks: I. Formation mechanism [PDF]
, 2017 Protoplanetary disk simulations show that a single planet can excite more than one spiral arm, possibly explaining recent observations of multiple spiral arms in some systems. In this paper, we explain the mechanism by which a planet excites multiple spiral arms in a protoplanetary disk.
