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…
The Green Valley is a Red Herring: Galaxy Zoo reveals two evolutionary pathways towards quenching of star formation in early- and late-type galaxies
Kevin Schawinski, C. Megan Urry, Brooke D. Simmons +13
We use SDSS+\textit{GALEX}+Galaxy Zoo data to study the quenching of star formation in low-redshift galaxies. We show that the green valley between the blue cloud of star-forming g…
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…
