Description
Since Virgo joined the O4 run in April 2024, the h(t) strain signal that may contain any gravitational wave signal has been reconstructed with a 2% accuracy in the 20-2000 Hz frequency band thanks to a good estimation of the interferometer optical response and the construction of accurate models of the mirrors actuators. I will present this h(t) reconstruction and how its current improvements, especially the reduction of its latency down below 2 seconds, may impact the transient detections in the futur O5 run.
