Strong gravitational lensing of waves can produce duplicate signals separated in time with different amplitudes. We consider the case which strong produces superthreshold gravitational-wave events and weaker subthreshold buried noise background. present GstLAL-based TargetEd Subthreshold Lensing seArch search method for using reduced template banks targeting specific confirmed events. perform a...
The optimization of industrial processes is a critical task for leveraging profitability and sustainability. To ensure the selection optimum process parameter levels in any process, numerous metaheuristic algorithms have been proposed so far. However, many are either computationally too expensive or become trapped pit local optima. counter these challenges, this paper, hybrid called PSO-GSA emp...
This paper presents techniques developed by the LIGO Scientic Collaboration to search for the stochastic gravitational-wave background using the co-located pair of LIGO interferometers at Hanford, WA. We use correlations between interferometers and environment monitoring instruments, as well as time-shifts between two interferometers (described here for the first time) to identify correlated no...
In the search for unmodeled gravitational wave bursts, there are a variety of methods that have been proposed to generate candidate events from time series data. Block Normal is a method of identifying candidate events by searching for places in the data stream where the characteristic statistics of the data change. These change-points divide the data into blocks in which the characteristics of...
Five cryogenic resonant gravitational antennas are now in operation. This is the first time that such a large number of high sensitive antennas are taking data and an agreement on data exchange has been signed by the responsible groups. The data exchanged will consist essentially in lists of ”candidate events”. In this paper the procedure used by the Rome group in order to obtain ”candidate eve...
