Journal Article
Kirby, M., Just, D. W., Zaritsky, D., Rudnick, G., Desjardins, T., Cool, R., Moustakas, J., Clowe, D., Lucia, G. D., Aragón-Salamanca, A., Desai, V., Finn, R., Halliday, C., Jablonka, P., Mann, J., Poggianti, B., Bian, F.-Y., & Liebst, K. (2019). Preprocessing among the Infalling Galaxy Population of EDisCS Clusters. Astrophysical Journal, 885(1), Article 6. https://doi.org/10.3847/1538-4357/ab44a0

We present results from a low-resolution spectroscopic survey for 21 galaxy clusters at 0.4 < z < 0.8 selected from the ESO Distant Cluster Survey. We measured spectra using the low-dispersion prism in IMACS on the Magellan Baade telescope and calcul... Read More about Preprocessing among the Infalling Galaxy Population of EDisCS Clusters.

Signatures of stellar accretion in MaNGA early-type galaxies (2019)
Journal Article
Oyarzún, G. A., Bundy, K., Westfall, K. B., Belfiore, F., Thomas, D., Maraston, C., Lian, J., Aragón-Salamanca, A., Zheng, Z., Gonzalez-Perez, V., Law, D. R., Drory, N., & Andrews, B. H. (2019). Signatures of stellar accretion in MaNGA early-type galaxies. Astrophysical Journal, 880(2), Article 111. https://doi.org/10.3847/1538-4357/ab297c

The late assembly of massive galaxies is thought to be dominated by stellar accretion in their outskirts (beyond 2 effective radii R e) due to dry, minor galaxy mergers. We use observations of 1010 passive early-type galaxies (ETGs) within z < 0.15 f... Read More about Signatures of stellar accretion in MaNGA early-type galaxies.

SDSS-IV MaNGA: Stellar Population Gradients Within Barred Galaxies (2019)
Journal Article
Fraser-McKelvie, A., Merrifield, M., Aragón-Salamanca, A., Peterken, T., Masters, K., Krawczyk, C., Andrews, B., Knapen, J. H., Kruk, S., Schaefer, A., Smethurst, R., Riffel, R., Brownstein, J., & Drory, N. (2019). SDSS-IV MaNGA: Stellar Population Gradients Within Barred Galaxies. Monthly Notices of the Royal Astronomical Society: Letters, 488(1), L6–L11. https://doi.org/10.1093/mnrasl/slz085

Bars in galaxies are thought to stimulate both inflow of material and radial mixing along them. Observational evidence for this mixing has been inconclusive so far however, limiting the evaluation of the impact of bars on galaxy evolution. We now use...

SDSS IV MaNGA: full spectroscopic bulge-disc decomposition of MaNGA early-type galaxies (2019)
Journal Article
Tabor, M., Merrifield, M., Aragón-Salamanca, A., Fraser-Mckelvie, A., Peterken, T., Smethurst, R., Drory, N., & Lane, R. R. (2019). SDSS IV MaNGA: full spectroscopic bulge-disc decomposition of MaNGA early-type galaxies. Monthly Notices of the Royal Astronomical Society, 485(2), 1546–1558. https://doi.org/10.1093/mnras/stz431

By applying spectroscopic decomposition methods to a sample of MaNGA early-type galaxies, we separate out spatially and kinematically distinct stellar populations, allowing us to explore the similarities and differences between galaxy bulges and disc...

Astrophysical Journal Supplement, 240(2), 1-25. https://doi.org/10.3847/1538-4365/aaf651

Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years of operation (2014 July–2017 July). This is the third data release for...

We present the results of a systematic search and characterisation of galaxies with morphological signatures of ram-pressure stripping, known as jellyfish galaxies, in the multi-cluster system A901/2, at z ∼ 0.165, as part of the OMEGA survey. By vis... Read More about OMEGA – OSIRIS mapping of emission-line galaxies in A901/2 – V. The rich population of jellyfish galaxies in the multi-cluster system Abell 901/2.
