Journal Article
Cheng, T. Y., Domínguez Sánchez, H., Vega-Ferrero, J., Conselice, C. J., Siudek, M., Aragón-Salamanca, A., …Scarpine, V. (2023). Lessons learned from the two largest Galaxy morphological classification catalogues built by convolutional neural networks. Monthly Notices of the Royal Astronomical Society, 518(2), 2794–2809. https://doi.org/10.1093/mnras/stac3228

We compare the two largest galaxy morphology catalogues, which separate early- and late-type galaxies at intermediate redshift. The two catalogues were built by applying supervised deep learning (convolutional neural networks, CNNs) to the Dark Energ...

Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters (2022)
Journal Article
Cornwell, D. J., Kuchner, U., Aragón-Salamanca, A., Gray, M. E., Pearce, F. R., Aguerri, J. A. L., …Trager, S. C. (2022). Forecasting the success of the WEAVE Wide-Field Cluster Survey on the extraction of the cosmic web filaments around galaxy clusters. Monthly Notices of the Royal Astronomical Society, 517(2), 1678–1694. https://doi.org/10.1093/mnras/stac2777

Next-generation wide-field spectroscopic surveys will observe the infall regions around large numbers of galaxy clusters with high sampling rates for the first time. Here we assess the feasibility of extracting the large-scale cosmic web around clust...

SDSS-IV MaNGA: the chemical co-evolution of gas and stars in spiral galaxies (2022)
Journal Article
Greener, M. J., Aragón-Salamanca, A., Merrifield, M., Peterken, T., Sazonova, E., Haggar, R., …Pan, K. (2022). SDSS-IV MaNGA: the chemical co-evolution of gas and stars in spiral galaxies. Monthly Notices of the Royal Astronomical Society, 516(1), 1275–1288. https://doi.org/10.1093/mnras/stac2355

We investigate archaeologically how the metallicity in both stellar and gaseous components of spiral galaxies of differing masses evolve with time, using data from the SDSS-IV MaNGA survey. For the stellar component, we can measure this evolution dir... Read More about SDSS-IV MaNGA: the chemical co-evolution of gas and stars in spiral galaxies.

SDSS-IV MaNGA: How the stellar populations of passive central galaxies depend on stellar and halo mass (2022)
Journal Article
Oyarzun, G. A., Bundy, K., Westfall, K. B., Tinker, J. L., Belfiore, F., Argudo-Fernandez, M., …Zhang, K. (2022). SDSS-IV MaNGA: How the stellar populations of passive central galaxies depend on stellar and halo mass. Astrophysical Journal, 933(1), Article 88. https://doi.org/10.3847/1538-4357/ac7048

We analyze spatially resolved and co-added SDSS-IV MaNGA spectra with signal-to-noise ratio ∼100 from 2200 passive central galaxies (z ∼ 0.05) to understand how central galaxy assembly depends on stellar mass (M*) and halo mass (Mh). We control for s... Read More about SDSS-IV MaNGA: How the stellar populations of passive central galaxies depend on stellar and halo mass.

SDSS-IV MaNGA: Cannibalism Caught in the Act - On the Frequency of Occurrence of Multiple Cores in Brightest Cluster Galaxies (2022)
Journal Article
Hsu, Y. H., Lin, Y. T., Huang, S., Nelson, D., Rodriguez-Gomez, V., Lai, H. T., …Schneider, D. P. (2022). SDSS-IV MaNGA: Cannibalism Caught in the Act - On the Frequency of Occurrence of Multiple Cores in Brightest Cluster Galaxies. Astrophysical Journal, 933(1), Article 61. https://doi.org/10.3847/1538-4357/ac6d66

Although it is generally accepted that massive galaxies form in a two-phased fashion, beginning with a rapid mass buildup through intense starburst activities followed by primarily dry mergers that mainly deposit stellar mass at outskirts, the late t...
