Galaxy Zoo DECaLS: Detailed visual morphology measurements from volunteers and deep learning for 314 000 galaxies (2021)
Journal Article
Walmsley, M., Lintott, C., Géron, T., Kruk, S., Krawczyk, C., Willett, K. W., Bamford, S., Kelvin, L. S., Fortson, L., Gal, Y., Keel, W., Masters, K. L., Mehta, V., Simmons, B. D., Smethurst, R., Smith, L., Baeten, E. M., & MacMillan, C. (2022). Galaxy Zoo DECaLS: Detailed visual morphology measurements from volunteers and deep learning for 314 000 galaxies. Monthly Notices of the Royal Astronomical Society, 509(3), 3966-3988. https://doi.org/10.1093/mnras/stab2093

We present Galaxy Zoo DECaLS: detailed visual morphological classifications for Dark Energy Camera Legacy Survey images of galaxies within the SDSS DR8 footprint. Deeper DECaLS images (r = 23.6 versus r = 22.2 from SDSS) reveal spiral arms, weak bars...

Quantifying Non-parametric Structure of High-redshift Galaxies with Deep Learning (2021)
Journal Article
Tohill, C., Ferreira, L., Conselice, C. J., Bamford, S. P., & Ferrari, F. (2021). Quantifying Non-parametric Structure of High-redshift Galaxies with Deep Learning. Astrophysical Journal, 916(1), Article 4. https://doi.org/10.3847/1538-4357/ac033c

At high redshift, due to both observational limitations and the variety of galaxy morphologies in the early universe, measuring galaxy structure can be challenging. Non-parametric measurements such as the CAS system have thus become an important tool... Read More about Quantifying Non-parametric Structure of High-redshift Galaxies with Deep Learning.

Recovering the origins of the lenticular galaxy NGC 3115 using multiband imaging (2021)
Journal Article
Buzzo, M. L., Cortesi, A., Hernandez-Jimenez, J. A., Coccato, L., Werle, A., Beraldo e Silva, L., Grossi, M., Vika, M., Barbosa, C. E., Lucatelli, G., Santana-Silva, L., Bamford, S., Debattista, V. P., Forbes, D. A., Overzier, R., Romanowsky, A. J., Ferrari, F., Brodie, J. P., & Mendes de Oliveira, C. (2021). Recovering the origins of the lenticular galaxy NGC 3115 using multiband imaging. Monthly Notices of the Royal Astronomical Society, 504(2), 2146-2167. https://doi.org/10.1093/mnras/stab941

A detailed study of the morphology of lenticular galaxies is an important way to understand how this type of galaxy is formed and evolves over time. Decomposing a galaxy into its components (disc, bulge, bar, ...) allows recovering the colour gradien...
