Are Milky-Way-like galaxies like the Milky Way? A view from SDSS-IV/MaNGA
Shuang Zhou, Alfonso Aragón-Salamanca, Michael Merrifield +3
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 M…
The impact of environment on the lives of disk galaxies as revealed by SDSS-IV MaNGA
Shuang Zhou, Michael Merrifield, Alfonso Aragón-Salamanca +4
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 disk galaxies,…
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…
Semi-analytic spectral fitting: simultaneously modelling the mass accumulation and chemical evolution in MaNGA spiral galaxies
Shuang Zhou, Michael Merrifield, Alfonso Aragon-Salamanca
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 cons…
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…
The halo of M105 and its group environment as traced by planetary nebula populations: II. Using kinematics of single stars to unveil the presence of intragroup light around the Leo I galaxies NGC 3384 and M105
J. Hartke, M. Arnaboldi, O. Gerhard +11
M105 is an early-type galaxy in the nearby Leo I group, the closest galaxy group to contain all galaxy types and therefore an excellent environment to explore the low-mass end of i…
