Scattered light noise at LIGO Livingston Observatory during O4
Debasmita Nandi, Anamaria Effler, Siddharth Soni +6
Scattered light is one of the most common sources of noise in the LIGO gravitational wave detectors. Light scattering is a highly non-linear process through which motion at low fre…
Search for continuous gravitational waves from neutron stars in five globular clusters in the first part of the fourth LIGO-Virgo-KAGRA observing run
Damon H. T. Cheung, Keith Riles, Rafel Amengual +14
We present the results of directed searches for continuous gravitational waves from unknown neutron stars in five Milky Way globular clusters. We carry out the searches in the LIGO…
The Sound of Noise: Leveraging the Inductive Bias of Pre-trained Audio Transformers for Glitch Identification in LIGO
Suyash Deshmukh, Chayan Chatterjee, Abigail Petulante +2
Transient noise artifacts, or glitches, fundamentally limit the sensitivity of gravitational-wave (GW) interferometers and can mimic true astrophysical signals, particularly the sh…
An Analysis of LIGO Glitches Using t-SNE During the First Part of the Fourth LIGO-Virgo-KAGRA Observing Run
Tabata Aira Ferreira, Gabriela González, Osvaldo Salas
This paper presents an analysis of noise transients observed in LIGO data during the first part of the fourth observing run, using the unsupervised machine learning technique t-dis…
Using t-SNE for characterizing glitches in LIGO detectors
Tabata Aira Ferreira, Gabriela González
Glitches are non-Gaussian noise transients originating from environmental and instrumental sources that contaminate data from gravitational wave detectors. Some glitches can even m…
Parameter Estimation Precision with Geocentric Gravitational Wave Interferometers: Monochromatic Signals
Manoel Felipe Sousa, Tabata Aira Ferreira, Massimo Tinto
We present a Fisher information matrix study of the parameter estimation precision achievable by a class of future space-based, "mid-band", gravitational wave (GW) interferometers…
