The separate effect of halo mass and stellar mass on the evolution of massive disc galaxies (2024)
Journal Article
Zhou, S., Aragón-Salamanca, A., & Merrifield, M. (2024). The separate effect of halo mass and stellar mass on the evolution of massive disc galaxies. Monthly Notices of the Royal Astronomical Society, 530(4), 4082-4093. https://doi.org/10.1093/mnras/stae1127

We analyse a sample of massive disk galaxies selected from the SDSS-IV/MaNGA survey to investigate how the evolution of these galaxies depends on their stellar and halo masses. We applied a semi-analytic spectral fitting approach to the data from dif... Read More about The separate effect of halo mass and stellar mass on the evolution of massive disc galaxies.

Where have all the low-metallicity galaxies gone? Tracing evolution in the mass-metallicity plane since a redshift of 0.7 (2023)
Journal Article
Zhou, S., Aragón-Salamanca, A., Merrifield, M., & Sampaio, V. M. (2023). Where have all the low-metallicity galaxies gone? Tracing evolution in the mass-metallicity plane since a redshift of 0.7. Monthly Notices of the Royal Astronomical Society, 527(2), 1935–1949. https://doi.org/10.1093/mnras/stad3330

Even over relatively recent epochs, galaxies have evolved significantly in their location in the mass–metallicity plane, which must be telling us something about the latter stages of galaxy evolution. In this paper, we analyse data from the LEGA-C su... Read More about Where have all the low-metallicity galaxies gone? Tracing evolution in the mass-metallicity plane since a redshift of 0.7.

The co-evolution of strong AGN and central galaxies in different environments (2023)
Journal Article
Sampaio, V. M., Aragón-Salamanca, A., Merrifield, M. R., De Carvalho, R. R., Zhou, S., & Ferreras, I. (2023). The co-evolution of strong AGN and central galaxies in different environments. Monthly Notices of the Royal Astronomical Society, 524(4), 5327–5339. https://doi.org/10.1093/mnras/stad2211

We exploit a sample of 80 000 Sloan Digital Sky Survey central galaxies to investigate the effect of active galactic nucleus (AGN) feedback on their evolution. We trace the demographics of optically selected AGN (Seyferts) as a function of their inte... Read More about The co-evolution of strong AGN and central galaxies in different environments.

Are Milky-Way-like galaxies like the Milky Way? A view from SDSS-IV/MaNGA (2023)
Journal Article
Zhou, S., Aragón-Salamanca, A., Merrifield, M., Andrews, B. H., Drory, N., & Lane, R. R. (2023). Are Milky-Way-like galaxies like the Milky Way? A view from SDSS-IV/MaNGA. Monthly Notices of the Royal Astronomical Society, 521(4), 5810-5825. https://doi.org/10.1093/mnras/stad853

In this paper, we place the Milky Way (MW) in the context of similar-looking galaxies in terms of their star-formation and chemical evolution histories. We select a sample of 138 Milky Way analogues (MWAs) from the SDSS-IV/MaNGA survey based on their... Read More about Are Milky-Way-like galaxies like the Milky Way? A view from SDSS-IV/MaNGA.

The impact of environment on the lives of disc galaxies as revealed by SDSS-IV MaNGA (2022)
Journal Article
Zhou, S., Merrifield, M., Aragón-Salamanca, A., Brownstein, J. R., Drory, N., Yan, R., & Lane, R. R. (2022). The impact of environment on the lives of disc galaxies as revealed by SDSS-IV MaNGA. Monthly Notices of the Royal Astronomical Society, 517(3), 3723-3731. https://doi.org/10.1093/mnras/stac2913

Environment has long been known to have significant impact on the evolution of galaxies, but here we seek to quantify the subtler differences that might be found in disc galaxies, depending on whether they are isolated, the most massive galaxy in a g...

Semi-analytic spectral fitting: simultaneously modelling the mass accumulation and chemical evolution in MaNGA spiral galaxies (2022)
Journal Article
Zhou, S., Merrifield, M., & Aragón-Salamanca, A. (2022). Semi-analytic spectral fitting: simultaneously modelling the mass accumulation and chemical evolution in MaNGA spiral galaxies. Monthly Notices of the Royal Astronomical Society, 513(4), 5446-5464. https://doi.org/10.1093/mnras/stac1279

We develop a novel semi-analytic spectral fitting approach to quantify the star-formation histories (SFHs) and chemical enrichment histories (ChEHs) of individual galaxies. We construct simple yet general chemical evolution models that account for ga...
