Point absorbers in Advanced LIGO

Kavli Affiliate: Lee McCuller | First 5 Authors: Aidan F. Brooks, Gabriele Vajente, Hiro Yamamoto, Rich Abbott, Carl Adams | Summary: Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly reduces the […]

Rapid accretion state transitions following the tidal disruption event AT2018fyk

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Thomas Wevers, Dheeraj R. Pasham, Sjoert van Velzen, James C. A. Miller-Jones, Phil Uttley | Summary: Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-Eddington levels and back over months – years timescales. This provides a unique opportunity to study […]

TIC 168789840: A Sextuply-Eclipsing Sextuple Star System

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Brian P. Powell, Veselin B. Kostov, Saul A. Rappaport, Tamas Borkovits, Petr Zasche | Summary: We report the discovery of a sextuply-eclipsing sextuple star system from TESS data, TIC 168789840, also known as TYC 7037-89-1, the first known sextuple system consisting of three eclipsing binaries. The […]

A Novel Modulation Scheme for Homodyne Detection Control

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Danial Shadmany, Benjamin Lane, Vivishek Sudhir, Nergis Mavalvala, | Summary: Controlling the quadrature measured by a homodyne detector is a universal task in continuous-variable quantum optics. However, deriving an error signal that is linear across theentire range of quadrature angles remains an open experimental problem. Here we […]
