Galaxy Zoo and SpArcFiRe: Constraints on spiral arm formation mechanisms from spiral arm number and pitch angles
Ross E. Hart, Steven P. Bamford, Wayne B. Hayes +7
In this paper we study the morphological properties of spiral galaxies, including measurements of spiral arm number and pitch angle. Using Galaxy Zoo 2, a stellar mass-complete sam…
SpArcFiRe: morphological selection effects due to reduced visibility of tightly winding arms in distant spiral galaxies
Tianrui, Peng, John Edward English +3
The Galaxy Zoo has provided morphological data on many galaxies. Several biases have been identified in the Galaxy Zoo data. Here we report on a newly discovered selection effect:…
On the nature and correction of the spurious S-wise spiral galaxy winding bias in Galaxy Zoo 1
Wayne Hayes, Darren Davis, Pedro Silva
The Galaxy Zoo 1 catalog displays a bias towards the S-wise winding direction in spiral galaxies which has yet to be explained. The lack of an explanation confounds our attempts to…
Scalable Automated Detection of Spiral Galaxy Arm Segments
Darren R. Davis, Wayne B. Hayes
Given an approximately centered image of a spiral galaxy, we describe an entirely automated method that finds, centers, and sizes the galaxy and then automatically extracts structu…
