In today’s paper, astronomer’s describe a newly-discovered Einstein ring in the Sculptor constellation.
In today’s astrobite, a group of astronomers experiences déjà vu while studying gravitational lensing.
More than 50 years ago, a Norwegian astronomer named Sjur Refsdal outlined an interesting new method for calculating the Hubble constant. Last November, astronomers found the perfect test case.
Measuring CMB distortions caused by gravitational lensing is a unique way of estimating galaxy cluster masses.
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 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.
