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 complex relationships between AGN, bars and bulges
Izzy L. Garland, Henry Best, Lucy F. Fortson +9
Context. Via scaling relations, it is well-known that active galactic nuclei (AGN) and bulges are linked. This link was thought to be driven by mergers, but recent studies show tha…
Resolving Galaxy Nuclei and Compact Stellar Systems as Engines of Galaxy Evolution
Julia Lamprecht, Izzy L. Garland, Daniel Jadlovsky +2
In this white paper we focus on compact stellar systems, star clusters, nuclear star clusters (NSCs), stripped nuclei, and ultra-compact dwarfs (UCDs), as engines of galaxy evoluti…
Strong Bars, Strong Inflow: The Effect of Bar Strength on Gas Inflow
Maelle Magnan, Tobias Geron, Izzy L. Garland +5
Stellar bars are elongated structures in disk galaxies that can torque and funnel gas inward, influencing galaxy evolution. While strong bars are known to induce rapid inflow, the…
High-cadence observations of galactic nuclei by the future two-band UV-photometry mission QUVIK
Michal ZajaÄek, Norbert Werner, Henry Best +12
The Quick Ultra-VIolet Kilonova surveyor (QUVIK), a two-band UV space telescope approved for funding as a Czech national science and technology mission, will focus on detecting ear…
