SDSS-IV MaNGA: when is morphology imprinted on galaxies? (2020)
Journal Article
Peterken, T., Merrifield, M., Aragón-Salamanca, A., Avila-Reese, V., Boardman, N. F., Drory, N., & Lane, R. R. (2021). SDSS-IV MaNGA: when is morphology imprinted on galaxies?. Monthly Notices of the Royal Astronomical Society: Letters, 500(1), L42-L46. https://doi.org/10.1093/mnrasl/slaa179

It remains an open question as to how long ago the morphology that we see in a present-day galaxy was typically imprinted. Studies of galaxy populations at different redshifts reveal that the balance of morphologies has changed over time, but such sn...

Resolving the Disc–Halo Degeneracy – II: NGC 6946 (2020)
Journal Article
Aniyan, S., Ponomareva, A. A., Freeman, K. C., Arnaboldi, M., Gerhard, O. E., Coccato, L., …Merrifield, M. (2021). Resolving the Disc–Halo Degeneracy – II: NGC 6946. Monthly Notices of the Royal Astronomical Society, 500(3), 3579-3593. https://doi.org/10.1093/mnras/staa3106

The mass-to-light ratio (M/L) is a key parameter in decomposing galactic rotation curves into contributions from the baryonic components and the dark halo of a galaxy. One direct observational method to determine the disc M/L is by calculating the su... Read More about Resolving the Disc–Halo Degeneracy – II: NGC 6946.

SDSS-IV MaNGA: The link between bars and the early cessation of star formation in spiral galaxies (2020)
Journal Article
Fraser-McKelvie, A., Merrifield, M., Aragón-Salamanca, A., Peterken, T., Kraljic, K., Masters, K., …Lane, R. R. (2020). SDSS-IV MaNGA: The link between bars and the early cessation of star formation in spiral galaxies. Monthly Notices of the Royal Astronomical Society, 499(1), 1116-1125. https://doi.org/10.1093/mnras/staa2866

Bars are common in low-redshift disc galaxies, and hence quantifying their influence on their host is of importance to the field of galaxy evolution. We determine the stellar populations and star formation histories of 245 barred galaxies from the Ma...

SDSS-IV MaNGA: Spatially resolved star formation in barred galaxies (2020)
Journal Article
Fraser-McKelvie, A., Aragón-Salamanca, A., Merrifield, M., Masters, K., Nair, P., Emsellem, E., …Neumann, J. (2020). SDSS-IV MaNGA: Spatially resolved star formation in barred galaxies. Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/staa1416

A novel wave-energy device is presented. Both a preliminary proof-of-principle of a working, scaled laboratory version of the energy device is shown as well as the derivation and analysis of a comprehensive mathematical and numerical model of the new...

SDSS-IV MaNGA: Excavating the fossil record of stellar populations in spiral galaxies (2020)
Journal Article

We perform a “fossil record” analysis for ≈800 low-redshift spiral galaxies, using STARLIGHT applied to integral field spectroscopic observations from the SDSS-IV MaNGA survey to obtain fully spatially-resolved high-resolution star formation historie...
