The Hercules stream as seen by APOGEE-2 South
(Oxford University Press, 2018)
The Hercules stream is a group of comoving stars in the solar neighbourhood, which can potentially be explained as a signature of either the outer Lindblad resonance (OLR) of a fast Galactic bar or the corotation resonance ...
Black hole spin and radio loudness in a LCDM universe
(Wiley Blackwell Publishing, Inc, 2009-12)
We use a combination of a cosmological N-body simulation of the concordance cold dark matter paradigm and a semi-analytic model of galaxy formation to investigate the spin development of central supermassive black holes ...
The gas metallicity gradient and the star formation activity of disc galaxies
(Wiley Blackwell Publishing, Inc, 2016-03-01)
We study oxygen abundance profiles of the gaseous disc components in simulatedgalaxies in a hierarchical universe. We analyse the disc metallicity gradients in relationto the stellar masses and star formation rates of the ...
Barred galaxies in the EAGLE cosmological hydrodynamical simulation
(Wiley Blackwell Publishing, Inc, 2017-07)
We examine the properties of barred disc galaxies in a ΛCDM cosmological hydrodynamical simulation from the EAGLE project. Our study follows the formation of 269 discs identified at z = 0 in the stellar mass range 10.6 < ...
Shapley Supercluster Survey: ram-pressure stripping versus tidal interactions in the Shapley supercluster
(2016)
We present two new examples of galaxies undergoing transformation in the Shapley supercluster core. These low-mass galaxies are members of the two clusters SC 1329-313 and SC 1327-312 z similar to 0.049). Integral-field ...
Ring galaxies in the EAGLE hydrodynamical simulations
(Wiley Blackwell Publishing, Inc, 2018-12)
We study the formation and evolution of ring galaxies in the Evolution and Assembly of GaLaxies and their Environments (EAGLE) simulations. We use the largest reference model Ref-L100N1504, a cubic cosmological volume of ...
