The SWELLS survey - V. A Salpeter stellar initial mass function in the bulges of massive spiral galaxies
A. A. Dutton, T. Treu, B. J. Brewer +6
Recent work has suggested that the stellar initial mass function (IMF) is not universal, but rather is correlated with galaxy stellar mass, stellar velocity dispersion, or morpholo…

Strong Gravitational Lensing as a Probe of Gravity, Dark-Matter and Super-Massive Black Holes
L. V. E. Koopmans, M. Auger, M. Barnabe +26
Whereas considerable effort has been afforded in understanding the properties of galaxies, a full physical picture, connecting their baryonic and dark-matter content, super-massive…

The Structure & Dynamics of Massive Early-type Galaxies: On Homology, Isothermality and Isotropy inside one Effective Radius
L. V. E. Koopmans, A. Bolton, T. Treu +7
Based on 58 SLACS strong-lens early-type galaxies with direct total-mass and stellar-velocity dispersion measurements, we find that inside one effective radius massive elliptical g…
