The fraction of clumpy star-forming galaxies in nearby galaxies from CLAUDS and HSC-SSP

Jürgen J. Popp, Hugh Dickinson, Stephen Serjeant +3

Massive, star-forming clumps are regions of intensive star-formation that are commonly observed in high-redshift () galaxies. Observations of low-redshift clumpy galaxy anal…

Galaxy Zoo CEERS: Bar fractions up to z~4.0

Tobias Géron, R. J. Smethurst, Hugh Dickinson +22

We study the evolution of the bar fraction in disc galaxies between using multi-band coloured images from JWST CEERS. These images were classified by citizen scient…

Transfer learning for galaxy feature detection: Finding Giant Star-forming Clumps in low redshift galaxies using Faster R-CNN

Jürgen Popp, Hugh Dickinson, Stephen Serjeant +8

Giant Star-forming Clumps (GSFCs) are areas of intensive star-formation that are commonly observed in high-redshift (z>1) galaxies but their formation and role in galaxy evolution…

Galaxy Zoo DESI: Detailed Morphology Measurements for 8.7M Galaxies in the DESI Legacy Imaging Surveys

Mike Walmsley, Tobias Géron, Sandor Kruk +13

We present detailed morphology measurements for 8.67 million galaxies in the DESI Legacy Imaging Surveys (DECaLS, MzLS, and BASS, plus DES). These are automated measurements made b…
