Galaxy Zoo: Unwinding the Winding Problem - Observations of Spiral Bulge Prominence and Arm Pitch Angles Suggest Local Spiral Galaxies are Winding
Karen L. Masters, Chris J. Lintott, Ross E. Hart +8
We use classifications provided by citizen scientists though Galaxy Zoo to investigate the correlation between bulge size and arm winding in spiral galaxies. Whilst the traditional…
Galaxy Zoo: constraining the origin of spiral arms
Ross E. Hart, Steven P. Bamford, William C. Keel +4
Since the discovery that the majority of low-redshift galaxies exhibit some level of spiral structure, a number of theories have been proposed as to why these patterns exist. A pop…
Galaxy Zoo: Secular evolution of barred galaxies from structural decomposition of multi-band images
Sandor J. Kruk, Chris J. Lintott, Steven P. Bamford +9
We present the results of two-component (disc+bar) and three-component (disc+bar+bulge) multiwavelength 2D photometric decompositions of barred galaxies in five SDSS bands (…
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…
Galaxy Zoo: major galaxy mergers are not a significant quenching pathway
Anna K. Weigel, Kevin Schawinski, Neven Caplar +9
We use stellar mass functions to study the properties and the significance of quenching through major galaxy mergers. In addition to SDSS DR7 and Galaxy Zoo 1 data, we use samples…
Galaxy Zoo: Finding offset discs and bars in SDSS galaxies
Sandor J. Kruk, Chris J. Lintott, Brooke D. Simmons +9
We use multi-wavelength SDSS images and Galaxy Zoo morphologies to identify a sample of late-type galaxies with an off-centre bar. We measure offsets in the range 0.2-2…
Galaxy Zoo: The interplay of quenching mechanisms in the group environment
R. J. Smethurst, C. J. Lintott, S. P. Bamford +5
Does the environment of a galaxy directly influence the quenching history of a galaxy? Here we investigate the detailed morphological structures and star formation histories of a s…
Galaxy Zoo: star-formation versus spiral arm number
Ross E. Hart, Steven P. Bamford, Kevin R. V Casteels +3
Spiral arms are common features in low-redshift disc galaxies, and are prominent sites of star-formation and dust obscuration. However, spiral structure can take many forms: from g…
Galaxy Zoo: Morphological Classifications for 120,000 Galaxies in HST Legacy Imaging
Kyle W. Willett, Melanie A. Galloway, Steven P. Bamford +18
We present the data release paper for the Galaxy Zoo: Hubble (GZH) project. This is the third phase in a large effort to measure reliable, detailed morphologies of galaxies by usin…
Galaxy Zoo: comparing the demographics of spiral arm number and a new method for correcting redshift bias
Ross E. Hart, Steven P. Bamford, Kyle W. Willett +8
The majority of galaxies in the local Universe exhibit spiral structure with a variety of forms. Many galaxies possess two prominent spiral arms, some have more, while others displ…
