A precise extragalactic test of General Relativity

Thomas E. Collett, Lindsay J. Oldham, Russell J. Smith +7

Einstein's theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby str…

Dark matter contraction and stellar-mass-to-light ratio gradients in massive early-type galaxies

Lindsay Oldham, Matthew Auger

We present models for the dark and luminous mass structure of 12 strong lensing early-type galaxies (ETGs). We combine pixel-based modelling of multiband HST/ACS imaging with Jeans…

Galaxy structure from multiple tracers: III. Radial variations in M87's IMF

Lindsay Oldham, Matthew Auger

We present the first constraints on stellar mass-to-light ratio gradients in an early-type galaxy (ETG) using multiple dynamical tracer populations to model the dark and luminous m…

Discovery of three strongly lensed quasars in the Sloan Digital Sky Survey

Peter R. Williams, Adriano Agnello, Tommaso Treu +12

We present the discovery of 3 quasar lenses in the Sloan Digital Sky Survey (SDSS), selected using two novel photometry-based selection techniques. The J0941+0518 system, with two…

The fundamental plane of evolving red nuggets

Lindsay Oldham, Matt Auger, Chris Fassnacht +5

We present an exploration of the mass structure of a sample of 12 strongly lensed massive, compact early-type galaxies at redshifts to provide further possible evidence…

SHARP - IV. An apparent flux ratio anomaly resolved by the edge-on disc in B0712+472

J. -W. Hsueh, L. Oldham, C. Spingola +6

Flux ratio anomalies in quasar lenses can be attributed to dark matter substructure surrounding the lensing galaxy and, thus, used to constrain the substructure mass fraction. Prev…
