Milky Way Analogues in MaNGA: Multi-Parameter Homogeneity and Comparison to the Milky Way
Nicholas Fraser Boardman, Gail Zasowski, Anil Seth +15
The Milky Way provides an ideal laboratory to test our understanding of galaxy evolution, owing to our ability to observe our Galaxy over fine scales. However, connecting the Galax…
Heterogeneity of Inverted Calcium II H:K Ratio Cluster Galaxies
K. A. Pimbblet, J. P. Crossett, A. Fraser-McKelvie
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 more A and B class stars. This ra…
From the Outside Looking in: What can Milky Way Analogues Tell us About the Star Formation Rate of Our Own Galaxy?
Amelia Fraser-McKelvie, Michael Merrifield, Alfonso Aragón-Salamanca
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…
Properties of barred galaxies in the MaNGA galaxy survey
A. Fraser-McKelvie, M. Merrifield, A. Aragón-Salamanca +2
We present the initial results of a census of 684 barred galaxies in the MaNGA galaxy survey. This large sample contains galaxies with a wide range of physical properties, and we a…
Time-slicing spiral galaxies with SDSS-IV MaNGA
Thomas Peterken, Amelia Fraser-McKelvie, Alfonso Aragón-Salamanca +6
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…
SDSS-IV MaNGA: Stellar Population Gradients Within Barred Galaxies
Amelia Fraser-McKelvie, Michael Merrifield, Alfonso Aragón-Salamanca +11
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, limitin…
The Effect of Minor and Major Mergers on the Evolution of Low Excitation Radio Galaxies
Yjan A. Gordon, Kevin A. Pimbblet, Sugata Kaviraj +8
We use deep, , -band imaging from the Dark Energy Camera Legacy Survey (DECaLS) to search for past, or ongoing, merger activit…
HI galaxies with little star formation: an abundance of LIERs
Vaishali Parkash, Michael J. I. Brown, T. H. Jarrett +2
We present a sample of 91 HI galaxies with little or no star formation and discuss the analysis of the integral field unit (IFU) spectra of 28 of these galaxies. We identified HI g…
SDSS IV MaNGA: Full spectroscopic bulge-disc decomposition of MaNGA early-type galaxies
Martha Tabor, Michael Merrifield, Alfonso Aragon-Salamanca +5
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 e…
SNITCH: Seeking a simple, informative star formation history inference tool
R. J. Smethurst, M. Merrifield, C. J. Lintott +7
Deriving a simple, analytic galaxy star formation history (SFH) using observational data is a complex task without the proper tool to hand. We therefore present SNITCH, an open sou…
