We report the results of a directed search for continuous gravitational-wave emission in a broad frequency range (between 50 and 1000 Hz) from the central compact object of the supernova remnant Cassiopeia A (Cas A). The data comes from the sixth science run of LIGO and the search is performed on the volunteer distributed computing network Einstein@Home. We find no significant signal candidate, and set the most constraining upper limits to date on the gravitational-wave emission from Cas A…

Characterizing the sensitivity of isolated continuous gravitational wave searches to binary orbits

- Physics, Computer SciencePhysical Review D
- 2019

The sensitivity of CW searches to signals from sources in binary systems over an exhaustive range of binary orbits is investigated and Monte-Carlo simulations are used to constrain the ranges of binary orbital parameters that leave a CW signal from a source in a binary orbit visible in a search for signals from an isolated source.
