A Gravitational-wave Measurement of the Hubble Constant Following the Second Observing Run of Advanced LIGO and Virgo
(American Astronomical Society, 2021-03)
This paper presents the gravitational-wave measurement of the Hubble constant (H0) using the detections from the first and second observing runs of the Advanced LIGO and Virgo detector network. The presence of the transient ...
All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems
(American Physical Society, 2021-03-12)
Rapidly spinning neutron stars are promising sources of continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter under extreme conditions. A significant fraction of ...
