Bridging the Gap Between Simply Parametrized and Free-Form Pixelated Models of Galaxy Lenses: The Case of WFI 2033-4723 Quad

Bernardo Barrera, Liliya L. R. Williams, Jonathan P. Coles +1

We study the radial and azimuthal mass distribution of the lensing galaxy in WFI2033-4723. Mindful of the fact that modeling results depend on modeling assumptions, we examine two…

The lens SW05 J143454.4+522850: a fossil group at redshift 0.6?

Philipp Denzel, Onur Çatmabacak, Jonathan P. Coles +8

Fossil groups are considered the end product of natural galaxy group evolution in which group members sink towards the centre of the gravitational potential due to dynamical fricti…

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…

The Hubble constant from eight time-delay galaxy lenses

Philipp Denzel, Jonathan P. Coles, Prasenjit Saha +1

We present a determination of the Hubble constant from the joint, free-form analysis of 8 strongly, quadruply lensing systems. In the concordance cosmology, we find $H_0 = 71.8^{+3…

Time Delay Lens Modelling Challenge

X. Ding, T. Treu, S. Birrer +26

In recent years, breakthroughs in methods and data have enabled gravitational time delays to emerge as a very powerful tool to measure the Hubble constant . However, published…

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…

Molecular dynamics simulations of bubble nucleation in dark matter detectors

Philipp Denzel, Jürg Diemand, Raymond Angélil

Bubble chambers and droplet detectors used in dosimetry and dark matter particle search experiments use a superheated metastable liquid in which nuclear recoils trigger bubble nucl…
