Eccentricity in Disguise? Insights from GW231123 and Numerically Simulated Binary Black Hole Merger Signals
Koustav Chandra, Johann Fernandes, Akshita Mittal +1
GW231123 is a gravitational-wave signal originating from the merger of a black hole binary with total mass , the largest ever detected by the LIGO-Virgo-Kagra C…

Binary Black Hole inspirals cannot hide their eccentricity
Johann Fernandes, Praveer Tiwari, Archana Pai
The events detected by the LIGO Virgo KAGRA collaboration over a period of 10 years have yielded a treasure trove of signals from compact binary coalescences. None of these events…

Improving the detection significance of gravitational wave transient searches with CNN models
Johann Fernandes, Archana Pai, Koustav Chandra
Gravitational wave (GW) transient searches rely on signal-noise discriminators to distinguish astrophysical signals from noise artefacts. These discriminators are typically tuned t…
