Abstract

The existence of gravitational waves reveals yet another method in which information is transmitted across the cosmos, bringing with it further insight into the inner workings of our universe. In order to detect such phenomena, we use ground based Laser Interferometers to measure the microscopic deformations in space-time and explore a new frontier in gravitational astronomy. However, such instrumentation also induces distortions in the gravitational waves henceforth diminishing the ability to extract accurate physical information. Moreover, the ability to extract a coherent signal amongst the noise remains an issue that requires constant improvement. The aim of this study is to understand the consequences of the distortions produced by the laser interferometer on the reconstructed gravitational waves from core collapse supernova. We will check the impact of the distortions on the astrophysical parameters that we compute from a gravitational wave candidate as seen in the LIGO instruments and existing software excess power algorithms. The results of which will be used to quantify the calibration errors for the ongoing optical triggered core collapse supernova search for the so called O3 data set. As a consequence, this study is to provide reports that introduce a wider range of calibration errors so that the impact on detection ranges and parameter estimations can be accurately estimated.

Gravitational Wave Calibration Error for Supernovae Core Collapse
