- In this article, we introduce a methodology based on an analytical model of a damped harmonic oscillator subject to random forcing to generate transient gravitational wave signals. Such a model incorporates a simulated linear high-frequency component that mirrors thegrowing characteristic frequency over time observed in numerical simulations of core-collapse supernova gravitational wave signals. Unliketraditional numerical simulations, the method proposed in this study requires minimal computational resources, which makes it particularlyadvantageous for tasks such as data analysis, detection, and reconstruction of gravitational wave transients. To verify the physical accuracyof the generated signals, they are compared against the amplitude spectral of current LIGO interferometers and a 3D numerical simulationof a core-collapse supernova gravitational wave signal from the Andresen et al. 2017 model s15.nr. The results indicate that this approachis effective in generating scalable signals that align with LIGO interferometric data, offering potential utility in various gravitational wavetransient investigations. © (2024), (Sociedad Mexicana de Fisica).
