| Abstract : | Glitches are non-Gaussian, non-astrophysical transients in the strain data of ground-based gravitational wave observatories like Advanced LIGO and Advanced Virgo. With morphologies similar to intermediate-mass black hole binaries, these glitches reduce the gravitational-wave search sensitivity to intermediate-mass black hole (IMBH) binary signals and affect their characterisation. Among them, the “Tomte” glitches are particularly problematic, frequently occurring in the detector data and hence if they are coincident between the detectors, they can be confused with IMBH signals. Such an example was 200114_020818. In this poster, I will present Bayesian parameter estimation results of a few Tomte glitches. Our analysis is an important step towards distinguishing intermediate-mass binary black hole signals from Tomte glitches in the upcoming observational runs of the International Gravitational Wave Network. |
