A new strategy for matching observed and simulated lensing galaxies

Philipp Denzel, Sampath Mukherjee, Prasenjit Saha

The study of strong-lensing systems conventionally involves constructing a mass distribution that can reproduce the observed multiply-imaging properties. Such mass reconstructions…

STRIDES: Spectroscopic and photometric characterization of the environment and effects of mass along the line of sight to the gravitational lenses DES J0408-5354 and WGD 2038-4008

E. J. Buckley-Geer, H. Lin, C. Rusu +65

In time-delay cosmography, three of the key ingredients are 1) determining the velocity dispersion of the lensing galaxy, 2) identifying galaxies and groups along the line of sight…

Lessons from a blind study of simulated lenses: image reconstructions do not always reproduce true convergence

Philipp Denzel, Sampath Mukherjee, Jonathan P. Coles +1

In the coming years, strong gravitational lens discoveries are expected to increase in frequency by two orders of magnitude. Lens-modelling techniques are being developed to prepar…

The Most Powerful Lenses in the Universe: Quasar Microlensing as a Probe of the Lensing Galaxy

David Pooley, Timo Anguita, Saloni Bhatiani +14

Optical and X-ray observations of strongly gravitationally lensed quasars (especially when four separate images of the quasar are produced) determine not only the amount of matter…

SEAGLE--II: Constraints on feedback models in galaxy formation from massive early type strong lens galaxies

Sampath Mukherjee, Leon V. E. Koopmans, R. Benton Metcalf +5

We use nine different galaxy formation scenarios in ten cosmological simulation boxes from the EAGLE suite of ΛCDM hydrodynamical simulations to assess the impact of feedback mecha…
