SDSS-IV MaNGA: the chemical co-evolution of gas and stars in spiral galaxies
Michael J. Greener, Alfonso Aragón-Salamanca, Michael Merrifield +7
We investigate archaeologically how the metallicity in both stellar and gaseous components of spiral galaxies of differing masses evolve with time, using data from the SDSS-IV MaNG…
Photometric Signature of Ultra-Harmonic Resonances in Barred Galaxies
Dhanesh Krishnarao, Zachary J. Pace, Elena D'Onghia +11
Bars may induce morphological features, such as rings, through their resonances. Previous studies suggested that the presence of 'dark-gaps', or regions of a galaxy where the diffe…
Size, shade or shape? The contribution of galaxies of different types to the star-formation history of the Universe from SDSS-IV MaNGA
Thomas Peterken, Alfonso Aragón-Salamanca, Michael Merrifield +7
By fitting stellar populations to SDSS-IV MaNGA survey observations of ~7000 suitably-weighted individual galaxies, we reconstruct the star-formation history of the Universe, which…
SDSS-IV MaNGA: the "G-dwarf problem" revisited
Michael J. Greener, Michael Merrifield, Alfonso Aragón-Salamanca +3
The levels of heavy elements in stars are the product of enhancement by previous stellar generations, and the distribution of this metallicity among the population contains clues t…
SDSS-IV MaNGA: When is morphology imprinted on galaxies?
Thomas Peterken, Michael Merrifield, Alfonso Aragón-Salamanca +4
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 reve…
SDSS-IV MaNGA: The link between bars and the early cessation of star formation in spiral galaxies
Amelia Fraser-McKelvie, Michael Merrifield, Alfonso Aragón-Salamanca +9
Bars are common in low-redshift disk galaxies, and hence quantifying their influence on their host is of importance to the field of galaxy evolution. We determine the stellar popul…
