Accelerating galaxy dynamical modeling using a neural network for joint lensing and kinematics analyses
Matthew R. Gomer, Sebastian Ertl, Luca Biggio +6
Strong gravitational lensing is a powerful tool to provide constraints on galaxy mass distributions and cosmological parameters, such as the Hubble constant, . Nevertheless, i…

Galaxy-lens determination of : the effect of the ellipse+shear modeling assumption
Matthew R. Gomer, Liliya L. R. Williams
Galaxy lenses are frequently modeled as an elliptical mass distribution with external shear and isothermal spheres to account for secondary and line-of-sight galaxies. There is sta…

The impact of CDM substructure and baryon-dark matter transition on the image positions of quad galaxy lenses
Matthew R. Gomer, Liliya L. R. Williams
The positions of multiple images in galaxy lenses are related to the galaxy mass distribution. Smooth elliptical mass profiles were previously shown to be inadequate in reproducing…
