Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run
E. Goetz, A. Neunzert, A. M. Knee +260
We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…
SiGMa-Net II: Distinguishing Binary Black Holes from Glitches
Soorya Narayan, Anupreeta More, Sunil Choudhary +2
With increasing sensitivity of the gravitational wave (GW) detectors, we expect a significant rise in the detectable GW events. To process, analyse and identify such large amounts…
Microlensing of long-duration gravitational wave signals originating from Galactic sources
Sudhagar Suyamprakasam, Sreekanth Harikumar, PaweÅ CiecielÄ g +3
Detection of quasi-monochromatic, long-duration (continuous) gravitational wave radiation emitted by, e.g., asymmetric rotating neutron stars in our Galaxy requires a long observat…
Identifying noise transients in gravitational-wave data arising from nonlinear couplings
Bernard Hall, Sudhagar Suyamprakasam, Nairwita Mazumder +2
Noise in various interferometer systems can sometimes couple non-linearly to create excess noise in the gravitational wave (GW) strain data. Third-order statistics, such as bicoher…
