Weighing galaxy clusters with the CMB
Measuring CMB distortions caused by gravitational lensing is a unique way of estimating galaxy cluster masses.
What would a binary black hole merger look like?
What kind of lens is a BBH merger? These authors present the first pictures of light sources lensed by numerical models of BBH mergers.
Kepler Discovers a Self-Lensing Star System
Kepler finds the signature of a transiting white dwarf. Instead blocking the light of its companion star, the white dwarf magnifies it, creating a light curve that periodically brightens.
