The co-evolution of strong AGN and central galaxies in different environments
V. M. Sampaio, A. Aragón-Salamanca, M. R. Merrifield +3
We exploit a sample of 80,000 SDSS central galaxies to investigate the effect of AGN feedback on their evolution. We trace the demographics of optically-selected AGN (Seyferts) as…
Clusters' far-reaching influence on narrow-angle tail radio galaxies
K de Vos, N. A. Hatch, M. R. Merrifield +1
In order to study the ram-pressure interaction between radio galaxies and the intracluster medium, we analyse a sample of 208 highly-bent narrow-angle tail radio sources (NATs) in…
An analytical model to kinematically identify thin discs in MaNGA galaxies
Meng Yang, Anne-Marie Weijmans, Matthew A. Bershady +3
We present an analytical model to identify thin discs in galaxies, and apply this model to a sample of SDSS MaNGA galaxies. This model fits the velocity and velocity dispersion fie…
Infrared lags in the light curves of AGN measured using a deep survey
E. Elmer, M. Merrifield, O. Almaini +2
Information on the structure around active galactic nuclei (AGN) has long been derived from measuring lags in their varying light output at different wavelengths. In principle, inf…
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…
