Source REconstruction of Arcs behind Cluster Halos (SourceREACH): A New Source Reconstruction Algorithm Optimized for Giant Arcs and Galaxy Cluster Lenses
Lana Eid, Charles Keeton
We introduce a new algorithm designed for use with extended lensed images, specifically giant arcs lensed by galaxy clusters. These highly magnified images contain important inform…
HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo
P. Cox, K. M. Butler, C. R. Keeton +24
We present a study of HerS-3, a dusty star-forming galaxy at zspec = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy s…
Constraints from the Giant Arc in Abell 370. A New Framework for Understanding Systematic Errors in Cluster Lens Modeling. IV. Constraints from the Giant Arc in Abell 370
Lana Eid, Charles R. Keeton
We aim to improve cluster lens modeling and source reconstruction by utilizing the full information in giant, caustic-crossing arcs lensed by galaxy clusters. Lens models are gener…
Autoencoder Reconstruction of Cosmological Microlensing Magnification Maps
Somayeh Khakpash, Federica Bianco, Georgios Vernardos +2
Enhanced modeling of microlensing variations in light curves of strongly lensed quasars improves measurements of cosmological time delays, the Hubble Constant, and quasar structure…
Comparisons Between Resolved Star Formation Rate and Gas Tracers in the Strongly Lensed Galaxy SDSS J0901+1814 at Cosmic Noon
Qingxiang Chen, Chelsea E. Sharon, Hiddo S. Algera +10
We report new radio observations of SDSS J090122.37+181432.3, a strongly lensed star-forming galaxy at . We image 1.4 GHz (L-band) and 3 GHz (S-band) continuum using the VL…
Statistical Bias in the Hubble Constant and Mass Power Law Slope for Mock Strong Lenses
Dilys Ruan, Charles R. Keeton
Strong gravitational lensing offers constraints on the Hubble constant that are independent of other methods. However, those constraints are subject to uncertainties in lens models…
