The impact of mass map truncation on strong lensing simulations
Lyne Van de Vyvere, Dominique Sluse, Sampath Mukherjee +2
Strong gravitational lensing is a powerful tool to measure cosmological parameters and to study galaxy evolution mechanisms. However, quantitative strong lensing studies often requ…
Hierarchical Inference With Bayesian Neural Networks: An Application to Strong Gravitational Lensing
Sebastian Wagner-Carena, Ji Won Park, Simon Birrer +3
In the past few years, approximate Bayesian Neural Networks (BNNs) have demonstrated the ability to produce statistically consistent posteriors on a wide range of inference problem…
Combining strong and weak lensing estimates in the Cosmos field
Felix Arjun Kuhn, Claudio Bruderer, Simon Birrer +2
We present a combined cosmic shear analysis of the modeling of line-of-sight distortions on strongly lensed extended arcs and galaxy shape measurements in the COSMOS field. We deve…
TDCOSMO III: Dark matter substructure meets dark energy -- the effects of (sub)halos on strong-lensing measurements of
Daniel Gilman, Simon Birrer, Tommaso Treu
Time delay cosmography uses the arrival time delays between images in strong gravitational lenses to measure cosmological parameters, in particular the Hubble constant . The l…
Cosmology Intertwined IV: The Age of the Universe and its Curvature
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +88
A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in…
Cosmology Intertwined III: and
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with t…
