Grand Design versus Multiarmed Spiral Galaxies: Dependence on Galaxy Structure

The Astronomical Journal
We developed an algorithm to use Galaxy Zoo 3D spiral arm masks produced by citizen scientist volunteers to semiautomatically classify spiral galaxies as either multiarmed or grand design spirals. Our final sample consists of 299 multiarmed and 245 grand

A Cloud-Scale View of the Molecular Gas Disk in the Whirlpool Galaxy and Beyond [PDF]

EPJ Web of Conferences, 2022
The nearby galaxy M51 (also known as the Whirlpool galaxy) hosts an iconic grand-design spiral pattern and both IRAM facilities conducted the first cloud-scale (∼50 pc resolution) survey of the molecular gas reservoir across a the disk of a massive star ...

Dust Emission in Galaxies at Millimeter Wavelengths: Cooling of star forming regions in NGC6946 [PDF]

EPJ Web of Conferences, 2022
Interstellar dust plays an important role in the formation of molecular gas and the heating and cooling of the interstellar medium. The spatial distribution of the mm-wavelength dust emission from galaxies is largely unexplored. The NIKA2 Guaranteed Time

A grand-design spiral galaxy with an ordered magnetic field at redshift 2.6 as resolved with ALMA and gravitational lensing

Monthly Notices of the Royal Astronomical Society: Letters
ABSTRACT Magnetic fields play an important role in the evolution of galaxies and in shaping the dynamics of their interstellar medium. However, the formation history of magnetic fields from initial seed-fields to well-ordered systems is not clear.
