Gravitational Lensing Corrections in Flat LambdaCDM Cosmology
Ronald Kantowski, Bin Chen, Xinyu Dai
We compute the deflection angle to order (m/r_0)^2 and m/r_0*Lambda r_0^2 for a light ray traveling in a flat LambdaCDM cosmology which encounters a completely condensed mass regio…

Distance-redshift from an optical metric that includes absorption
Bin Chen, Ronald Kantowski
We show that it is possible to equate the intensity reduction of a light wave caused by weak absorption with a geometrical reduction in intensity caused by a "transverse" conformal…

Including Absorption in Gordon's Optical Metric
B. Chen, R. Kantowski
We show that Gordon's optical metric on a curved spacetime can be generalized to include absorption by allowing the metric to become complex. We demonstrate its use in the realm of…
