A Simple Gravitational Lens Model For Cosmic Voids
Bin Chen, Ronald Kantowski, Xinyu Dai
We present a simple gravitational lens model to illustrate the ease of using the embedded lensing theory when studying cosmic voids. It confirms the previously used repulsive lensi…
Embedded Lensing Time Delays, the Fermat Potential, and the Integrated Sachs-Wolfe Effect
Bin Chen, Ronald Kantowski, Xinyu Dai
We derive the Fermat potential for a spherically symmetric lens embedded in an FLRW cosmology and use it to investigate the late-time integrated Sachs-Wolfe (ISW) effect, i.e., sec…
Dust, Gas, and Metallicities of Cosmologically Distant Lens Galaxies
Bin Chen, Xinyu Dai, Christopher S. Kochanek +1
We homogeneously analyzed the \chandra\ X-ray observations of 10 gravitational lenses, HE 0047-1756, QJ 0158-4325, SDSS 0246-0805, HE 0435-1223, SDSS 0924+0219, SDSS 1004+4112, HE…
The Structure of HE 1104-1805 from Infrared to X-Ray
Jeffrey A. Blackburne, Christopher S. Kochanek, Bin Chen +2
The gravitationally lensed quasar HE 1104-1805 has been observed at a variety of wavelengths ranging from the mid-infrared to X-ray for nearly 20 years. We combine flux ratios from…
The Embedded Transparent Lens and Fermat's Least-Time Principle
Ronald Kantowski, Bin Chen, Xinyu Dai
We present a simplified version of the lowest-order embedded point mass gravitational lens theory and then make the extension of this theory to any embedded transparent lens. Embed…
