Evidence for non-merger co-evolution of galaxies and their supermassive black holes
R. J. Smethurst, R. S. Beckmann, B. D. Simmons +7
Recent observational and theoretical studies have suggested that supermassive black holes (SMBHs) grow mostly through non-merger (`secular') processes. Since galaxy mergers lead to…
Supermassive black holes in merger-free galaxies have higher spins which are preferentially aligned with their host galaxy
R. S. Beckmann, R. J. Smethurst, B. D. Simmons +7
Here we use the Horizon-AGN simulation to test whether the spins of SMBHs in merger-free galaxies are higher. We select samples using an observationally motivated bulge-to-total ma…
Preparing for low surface brightness science with the Vera C. Rubin Observatory: characterisation of tidal features from mock images
G. Martin, A. E. Bazkiaei, M. Spavone +50
Tidal features in the outskirts of galaxies yield unique information about their past interactions and are a key prediction of the hierarchical structure formation paradigm. The Ve…
Radio AGN in nearby dwarf galaxies: the important role of AGN in dwarf-galaxy evolution
F. Davis, S. Kaviraj, M. J. Hardcastle +8
We combine deep optical and radio data, from the Hyper Suprime-Cam and the Low-Frequency Array (LOFAR) respectively, to study 78 radio AGN in nearby (z<0.5) dwarf galaxies. Compari…
Extremely massive disc galaxies in the nearby Universe form through gas-rich minor mergers
R. A. Jackson, S. Kaviraj, G. Martin +5
In our hierarchical structure-formation paradigm, the observed morphological evolution of massive galaxies -- from rotationally-supported discs to dispersion-dominated spheroids --…
How the spectral energy distribution and galaxy morphology constrain each other, with application to morphological selection using galaxy colours
Emir Uzeirbegovic, Garreth Martin, Sugata Kaviraj
We introduce an empirical methodology to study how the spectral energy distribution (SED) and galaxy morphology constrain each other and implement this on 8000 galaxies from the HS…
