Extending Ground-Based Gravitational-Wave Sensitivity to 5 Hz
Amit Singh Ubhi, Lari Koponen, Jiri Smetana +11
Extending the sensitivity of terrestrial gravitational-wave detectors below 20 Hz is a long-standing challenge, limited by ground motion and inertial sensing noise. In this letter,…

Enhancing high frequency sensitivity of gravitational wave detectors with sloshing-Sagnac interferometer
Teng Zhang, Denis Martynov, Stefan Danilishin +1
Sensitivity of gravitational-wave detectors is limited in the high-frequency band by quantum shot noise and eventually limited by the optical loss in signal recycling cavity. This…
A six degree-of-freedom fused silica seismometer: Design and tests of a metal prototype
Amit Singh Ubhi, Jiri Smetana, Teng Zhang +6
Ground vibrations couple to the longitudinal and angular motion of the aLIGO test masses and limit the observatory sensitivity below 30\,Hz. Novel inertial sensors have the potenti…
Towards observing the neutron star collapse with gravitational wave detectors
Teng Zhang, Jiří Smetana, Yikang Chen +5
Gravitational waves from binary neutron star inspirals have been detected along with the electromagnetic transients coming from the aftermath of the merger in GW170817. However, mu…
