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 Role of Baryonic and Dark Matter in Bar Kinematics
Tobias Géron, Kai Zhu, Steph Campbell +3
Simulations predict that bars in galaxies should slow down over time. This is often attributed to the exchange of angular momentum between the bar and other regions of the galaxy,…
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…
Galaxy Zoo: Cosmic Dawn -- morphological classifications for over 41,000 galaxies in the Euclid Deep Field North from the Hawaii Two-0 Cosmic Dawn survey
James Pearson, Hugh Dickinson, Stephen Serjeant +22
We present morphological classifications of over 41,000 galaxies out to across six square degrees of the Euclid Deep Field North (EDFN) from the Hawaii Twenty…
Spatio-Spectroscopic Representation Learning using Unsupervised Convolutional Long-Short Term Memory Networks
Kameswara Bharadwaj Mantha, Lucy Fortson, Ramanakumar Sankar +8
Integral Field Spectroscopy (IFS) surveys offer a unique new landscape in which to learn in both spatial and spectroscopic dimensions and could help uncover previously unknown insi…
Bars in low-density environments rotate faster than bars in dense regions
Natalia Puczek, Tobias Géron, Rebecca J. Smethurst +1
Does the environment of a galaxy directly influence the kinematics of its bar? We present observational evidence that bars in high-density environments exhibit significantly slower…
