Point absorbers in Advanced LIGO [PDF]
Applied Optics, 2021 Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nanometer scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly reduce the sensitivity of the interferometer directly though a reduction in the power ...

Squeezing in Gravitational Wave Detectors
Galaxies, 2022 Injecting optical squeezed states of light, a technique known as squeezing, is now a tool for gravitational wave detection. Its ability to reduce quantum noise is helping to reveal more gravitational wave transients, expanding the catalog of observations

Analysis of the heterogenous structural states of the hexameric ATPase PilU of the type IV pili from Vibrio cholerae. [PDF]
Protein SciAbstract Type IV pili (T4P) mediate surface motility, host interactions, and DNA uptake through cycles of extension and retraction. While the primary retraction ATPase PilT has been extensively characterized, its homolog PilU remains less well understood despite being demonstrated as a PilT‐dependent retraction ATPase.
