Heterogeneity of inverted calcium?ii H:K ratio cluster galaxies (2019)
Journal Article
Pimbblet, K. A., Crossett, J. P., & Fraser-McKelvie, A. (2019). Heterogeneity of inverted calcium?ii H:K ratio cluster galaxies. Monthly Notices of the Royal Astronomical Society, 490(1), 455-466. https://doi.org/10.1093/mnras/stz2549

© 2019 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society The ratio of calcium II H plus H∊ to calcium II K inverts as a galaxy stellar population moves from being dominated by older stars to possessing mor...

From the outside looking in: what can Milky Way Analogues tell us about the star formation rate of our own galaxy? (2019)
Journal Article
Fraser-Mckelvie, A., Merrifield, M., & Aragón-Salamanca, A. (2019). From the outside looking in: what can Milky Way Analogues tell us about the star formation rate of our own galaxy?. Monthly Notices of the Royal Astronomical Society, 489(4), 5030–5036. https://doi.org/10.1093/mnras/stz2493

The Milky Way has been described as an anaemic spiral, but is its star formation rate (SFR) unusually low when compared to its peers? To answer this question, we define a sample of Milky Way Analogues (MWAs) based on stringent cuts on the best litera...

Time-slicing spiral galaxies with SDSS-IV MaNGA (2019)
Journal Article
Peterken, T., Fraser-Mckelvie, A., Aragón-Salamanca, A., Merrifield, M., Kraljic, K., Knapen, J. H., …Drory, N. (2019). Time-slicing spiral galaxies with SDSS-IV MaNGA. Monthly Notices of the Royal Astronomical Society, 489(1), 1338–1343. https://doi.org/10.1093/mnras/stz2204/5548799

Spectra of galaxies contain a wealth of information about the stellar populations from which they are made. With integral-field unit (IFU) surveys, such data can be used to map out stellar population properties across the face of a galaxy, allowing o...

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., …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., …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...
