Spiral Morphology and Radial Migration: Kinematically heating, cooling, and cold
Kathryne J. Daniel, M. E. Wisz, Karen L. Masters +3
Transient spiral arms are known to drive radial redistribution of stars and thus could play a central role in shaping disk galaxies, including modifying, over time, the age, chemic…
Deep Learning Segmentation of Spiral Arms and Bars for 600,000 Galaxies in DESI
Ashley Spindler, Mike Walmsley, Karen L. Masters +4
We present a catalogue of segmentation maps identifying the extent of spiral arms and bars of 639,636 galaxies in the DESI Legacy Survey. To produce these maps, we have trained a d…
Galaxy Zoo Bar Lengths: A Catalogue of Measurements from Hubble Space Telescope Images and the Evolution of Galactic Bar Structure at z < 1
Tenley Hutchinson-Smith, Brooke D. Simmons, Karen L. Masters +12
Understanding the role of galactic scale bars in disk galaxy evolution requires detailed measurements of bar properties across galaxies hosting bars at many redshifts. We present m…
The effects of bar strength and kinematics on galaxy evolution II: The global and local impacts of slow-strong bars
Petra Mengistu, Karen L. Masters, Tobias Geron +3
There is now clear evidence, from a variety of studies, that galactic bars contribute to and/or accelerate processes which quench galaxies. However, bars have a variety of strength…
Timescales for the Effects of Interactions on Galaxy Properties and SMBH Growth
D. O'Ryan, B. D. Simmons, A. L. Faisst +15
Galaxy interaction and merging have clear effects on the systems involved. We find an increase in the star formation rate (SFR), potential ignition of active galactic nuclei (AGN)…
The Impact of Bars, Spirals and Bulge-Size on Gas-Phase Metallicity Gradients in MaNGA Galaxies
M. E. Wisz, Karen L. Masters, Kathryne J. Daniel +2
As galaxies evolve over time, the orbits of their constituent stars are expected to change in size and shape, moving stars away from their birth radius. Radial gas flows are also e…
HI-MaNGA: Results from (21cm-HI) single-dish observations of MaNGA Survey Galaxies
Karen Masters, David Stark
In a poster presentation for IAU Symposium 392: "Neutral hydrogen in and around galaxies in the SKA era", we gave an overview of the HI-MaNGA project which is working to obtain com…
Structural Decomposition of Merger-Free Galaxies Hosting Luminous AGNs
Matthew J. Fahey, Izzy. L. Garland, Brooke. D. Simmons +10
Active galactic nucleus (AGN) growth in disk-dominated, merger-free galaxies is poorly understood, largely due to the difficulty in disentangling the AGN emission from that of the…
Galaxy Zoo: Morphologies based on UKIDSS NIR Imaging for 71,052 Galaxies
Karen L. Masters, Melanie Galloway, Lucy Fortson +6
We present morphological classifications based on Galaxy Zoo analysis of 71,052 galaxies with imaging from the United Kingdom Infrared Telescope Infrared Deep Sky Survey (UKIDSS).…
The Strength of Bisymmetric Modes in SDSS-IV/MaNGA Barred Galaxy Kinematics
Brian DiGiorgio Zanger, Kyle B. Westfall, Kevin Bundy +7
The SDSS-IV/MaNGA Survey data provide an unprecedented opportunity to study the internal motions of galaxies and, in particular, represent the largest sample of barred galaxy kinem…
Galaxy Zoo DESI: large-scale bars as a secular mechanism for triggering AGN
Izzy L. Garland, Mike Walmsley, Maddie S. Silcock +13
Despite the evidence that supermassive black holes (SMBHs) co-evolve with their host galaxy, and that most of the growth of these SMBHs occurs via merger-free processes, the underl…
The effects of bar strength and kinematics on galaxy evolution: slow strong bars affect their hosts the most
Tobias Géron, R. J. Smethurst, Chris Lintott +5
We study how bar strength and bar kinematics affect star formation in different regions of the bar by creating radial profiles of EW[H] and D4000 using data from SDSS-…
The ALMaQUEST Survey XV: The Dependence of the Molecular-to-Atomic Gas Ratios on Resolved Optical Diagnostics
Niankun Yu, Zheng Zheng, Chao-Wei Tsai +14
The atomic-to-molecular gas conversion is a critical step in the baryon cycle of galaxies, which sets the initial conditions for subsequent star formation and influences the multi-…
Using HI observations of low-mass galaxies to test ultra-light axion dark matter
James T. Garland, Karen L. Masters, Daniel Grin
We evaluate recent and upcoming low-redshift neutral hydrogen (HI) surveys as a cosmological probe of small scale structure with a goal of determining the survey criteria necessary…
Outflows in Star-forming Galaxies: Stacking Analyses of Resolved Winds and the Relation to Their Hosts' Properties
Guido Roberts-Borsani, Amélie Saintonge, Karen L. Masters +1
Outflows form an integral component in regulating the gas cycling in and out of galaxies, although their impact on the galaxy hosts is still poorly understood. Here we present an a…
SDSS-IV MaNGA: pattern speeds of barred galaxies
Rui Guo, Shude Mao, E. Athanassoula +5
The MaNGA project has obtained IFU data for several thousand nearby galaxies, including barred galaxies. With the two dimensional spectral and kinematic information provided by IFU…
Probing the kinematic morphology-density relation of early-type galaxies with MaNGA
J. E. Greene, A. Leauthaud, E. Emsellem +17
The "kinematic" morphology-density relation for early-type galaxies posits that those galaxies with low angular momentum are preferentially found in the highest-density regions of…
SDSS-IV MaNGA: Properties of galaxies with kinematically decoupled stellar and gaseous components
Yifei Jin, Yanmei Chen, Yong Shi +30
We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical…

We measure the stellar mass-star formation rate relation in star-forming disk galaxies at z<0.085, using Galaxy~Zoo morphologies to examine different populations of spirals as clas…
Misalignment between cold gas and stellar components in early-type galaxies
O. Ivy Wong, K. Schawinski, G. I. G. Józsa +5
Recent work suggests blue ellipticals form in mergers and migrate quickly from the blue cloud of star-forming galaxies to the red sequence of passively evolving galaxies, perhaps a…
Galaxy Zoo: Evidence for Diverse Star Formation Histories through the Green Valley
