A Weber bar is a device designed to detect gravitational waves, first devised and constructed by physicist Joseph Weber at the University of Maryland. The device consisted of aluminium cylinders, 2 meters in length and 1 meter in diameter , antennae for detecting gravitational waves .
PyCBC is an open source software package primarily written in the Python programming language which is designed for use in gravitational-wave astronomy and gravitational-wave data analysis. [1] PyCBC contains modules for signal processing, FFT , matched filtering , gravitational waveform generation, among other tasks common in gravitational ...
The earliest type was the room-temperature bar-shaped antenna called a Weber bar; these were dominant in 1960s and 1970s and many were built around the world. It was claimed by Weber and some others in the late 1960s and early 1970s that these devices detected gravitational waves; however, other experimenters failed to detect gravitational ...
Allegro was a ground-based, cryogenic resonant Weber bar, gravitational-wave detector [1] run by Warren Johnson, et al. at Louisiana State University in Baton Rouge, Louisiana. The detector was commissioned in the early 1990s, and was decommissioned in 2008.

Direct detection of gravitational waves had long been sought. Their discovery has launched a new branch of astronomy to complement electromagnetic telescopes and neutrino observatories. Joseph Weber pioneered the effort to detect gravitational waves in the 1960s through his work on resonant mass bar detectors. Bar detectors continue to be used ...
The detection of gravitational waves within the output of the detectors (typically known as the "strain") is a complex process. Currently, most of the data processing is done within the LIGO-Virgo-KAGRA (LVK) collaboration; teams outside of the collaboration also produce results on the data once it is released publicly.
