Observations of the Initial Formation and Evolution of Spiral galaxies at in the CANDELS fields
Berta Margalef-Bentabol, Christopher J. Conselice, Boris Haeussler +4
Many aspects concerning the formation of spiral and disc galaxies remain unresolved, despite their discovery and detailed study over the past years. As such, we present the r…
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: 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…
Leaving the dark ages with AMIGA
Alberto Manrique, Eduard Salvador-Solé, Enric Juan +6
We present an Analytic Model of Intergalactic-medium and GAlaxy evolution since the dark ages. AMIGA is in the spirit of the popular semi-analytic models of galaxy formation, altho…
Galaxy And Mass Assembly (GAMA): Refining the Local Galaxy Merger Rate using Morphological Information
Kevin R. V. Casteels, Christopher J. Conselice, Steven P. Bamford +16
We use the Galaxy And Mass Assembly (GAMA) survey to measure the local Universe mass dependent merger fraction and merger rate using galaxy pairs and the CAS structural method, whi…
Galaxy Zoo: CANDELS Barred Disks and Bar Fractions
B. D. Simmons, Thomas Melvin, Chris Lintott +39
The formation of bars in disk galaxies is a tracer of the dynamical maturity of the population. Previous studies have found that the incidence of bars in disks decreases from the l…
Galaxy Zoo: Are Bars Responsible for the Feeding of Active Galactic Nuclei at 0.2 < z < 1.0?
Edmond Cheung, Jonathan R. Trump, E. Athanassoula +19
We present a new study investigating whether active galactic nuclei (AGN) beyond the local universe are preferentially fed via large-scale bars. Our investigation combines data fro…
Galaxy Zoo: An independent look at the evolution of the bar fraction over the last eight billion years from HST-COSMOS
Thomas Melvin, Karen Masters, Chris Lintott +11
We measure the redshift evolution of the bar fraction in a sample of 2380 visually selected disc galaxies found in Cosmic Evolution Survey (COSMOS) Hubble Space Telescope (HST) ima…
Galaxy Zoo: Quantifying Morphological Indicators of Galaxy Interaction
Kevin R. V. Casteels, Steven P. Bamford, Ramin A. Skibba +6
We use Galaxy Zoo 2 visual classifications to study the morphological signatures of interaction between similar-mass galaxy pairs in the Sloan Digital Sky Survey. We find that many…
