Multiplane gravitational lenses with an abundance of images
Charles R. Keeton, Erik Lundberg, Sean Perry
We consider gravitational lensing of a background source by a finite system of point-masses. The problem of determining the maximum possible number of lensed images has been comple…
Asymmetric Light Bending in the Equatorial Kerr Metric
Arthur B. Congdon, Savitri V. Iyer, Charles R. Keeton
The observation of the bending of light by mass, now known as gravitational lensing, was key in establishing general relativity as one of the pillars of modern physics. In the past…
Deep XMM-Newton Observations of an X-ray Weak, Broad Absorption Line Quasar at
Jinyi Yang, Xiaohui Fan, Feige Wang +14
We report X-ray observations of the most distant known gravitationally lensed quasar, J0439+1634 at , which is also a broad absorption line (BAL) quasar, using the XMM-Newt…
ALMA Observations of the Sub-kpc Structure of the Host Galaxy of a z= 6.5 Lensed Quasar: A Rotationally-Supported Hyper-Starburst System at the Epoch of Reionization
Minghao Yue, Jinyi Yang, Xiaohui Fan +11
We report ALMA observations of the dust continuum and {\cii} emission of the host galaxy of J0439+1634, a gravitationally lensed quasar at . Gravitational lensing boosts the…
Systematic vs. Statistical Uncertainties in Masses and Magnifications of the Hubble Frontier Fields
Catie A Raney, Charles R Keeton, Sean Brennan +1
The Hubble Frontier Fields data, along with multiple data sets obtained by other telescopes, have provided some of the most extensive constraints on cluster lenses to date. Multipl…
Exploring Effects on Magnifications due to Line-of-Sight Galaxies in the Hubble Frontier Fields
Catie A. Raney, Charles R. Keeton, Sean Brennan
Cluster lensing has become an important tool in the search for high redshift galaxies through its ability to magnify sources. In order to determine the intrinsic properties of thes…
