Non-uniform Birefringence in Highly-reflective Substrate-Transferred GaAs/AlGaAs Coatings at 1064 nm
Andri M. Gretarsson, Ambroise L. M. Juston, Benjamin Nicolai +8
Using a custom-built scanning system, we generated maps of birefringence on reflection at ~nm from single-crystal GaAs/AlGaAs Bragg reflectors (hencefort…

Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…
