DOI: 10.1088/1361-6382/aab658
Abstract: Advanced LIGO's raw detector output needs to be calibrated to compute dimensionless strain h(t). Calibrated strain data is produced in the time domain using both a low-latency, online procedure and a high-latency, offline procedure. The… read more here.

DOI: 10.1088/1475-7516/2023/04/024
Abstract: String cosmology models predict a relic background of gravitational-wave (GW) radiation in the early universe. The GW energy spectrum of radiated power increases rapidly with the frequency, and therefore it becomes a potential and meaningful… read more here.

DOI: 10.1103/physrevd.100.061101
Abstract: The stochastic gravitational-wave background is a superposition of sources that are either too weak or too numerous to detect individually. In this study we present the results from a cross-correlation analysis on data from Advanced… read more here.
