GEO600 beam splitter thermal compensation system: new design and commissioning
Séverin Nadji, Holger Wittel, Nikhil Mukund +8
Gravitational waves have revolutionised the field of astronomy by providing scientists with a new way to observe the universe and gain a better understanding of exotic objects like…
Matrix Heater in the Gravitational Wave Observatory GEO 600
Holger Wittel, Christoph Affeldt, Aparna Bisht +7
Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfe…
Narrow-band search of continuous gravitational-wave signals from Crab and Vela pulsars in Virgo VSR4 data
The LIGO Scientific Collaboration, the Virgo Collaboration, J. Aasi +894
In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In orde…
Implementation and testing of the first prompt search for gravitational wave transients with electromagnetic counterparts
The LIGO Scientific Collaboration, Virgo Collaboration, J. Abadie +815
Aims. A transient astrophysical event observed in both gravitational wave (GW) and electromagnetic (EM) channels would yield rich scientific rewards. A first program initiating EM…
