Galaxy Zoo: dust in spiral galaxies★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We investigate the effect of dust on spiral galaxies by measuring the inclination dependence of optical colours for 24 276 well-resolved Sloan Digital Sky Survey (SDSS) galaxies visually classified via the Galaxy Zoo project.

Spin Parity of Spiral Galaxies. I. Corroborative Evidence for Trailing Spirals [PDF]
The Astrophysical Journal, 2019 Whether the spiral structure of galaxies is trailing or leading has been a subject of debate. We present a new spin parity catalog of 146 spiral galaxies that lists the following three pieces of information: whether the spiral structure observed on the ...

A photometrically and spectroscopically confirmed population of passive spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 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.

A Relativistic Entropic Hamiltonian–Lagrangian Approach to the Entropy Production of Spiral Galaxies in Hyperbolic Spacetime [PDF]
Universe, 2021 Double-spiral galaxies are common in the Universe. It is known that the logarithmic double spiral is a Maximum Entropy geometry in hyperbolic (flat) spacetime that well represents an idealised spiral galaxy, with its central supermassive black hole (SMBH)

Multiple mechanisms quench passive spiral galaxies [PDF]
, 2017 We examine the properties of a sample of 35 nearby passive spiral galaxies in order to determine their dominant quenching mechanism(s). All five low-mass (M⋆ < 1 × 1010 M⊙) passive spiral galaxies are located in the rich Virgo cluster.

Color Differences between Clockwise and Counterclockwise Spiral Galaxies [PDF]
Galaxies, 2013 While spiral galaxies observed from Earth clearly seem to spin in different directions, little is yet known about other differences between galaxies that spin clockwise and galaxies that spin counterclockwise.

A New Statistical Analysis of the Morphology of Spiral Galaxies
The Astronomical JournalMorphology is the starting point for understanding galaxies. Elmegreen et al. classified spiral galaxies into flocculent, multiple-arm, and grand-design galaxies based on the regularity of their spiral arm structure.

Superluminous Spiral Galaxies [PDF]
The Astrophysical Journal, 2016 We report the discovery of spiral galaxies that are as optically luminous as elliptical brightest cluster galaxies, with r-band monochromatic luminosity L_r = 8–14L* (4.3–7.5 × 10^(44) erg s^(−1)).

Galaxy Zoo:passive red spirals [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We study the spectroscopic properties and environments of red (or passive) spiral galaxies found by the Galaxy Zoo project. By carefully selecting face-on disc-dominated spirals, we construct a sample of truly passive discs (i.e.
