Intervening Gravitational waves affect the time it takes for signals to reach from source to telescopes. Using this principle we can detect GWs using
Pulsar Timing Arrays
Cosmic Microwave Background Radiation
21 cm Hydrogen
gamma ray bursts
gamma ray bursts and r process outflows are believed to happen in
inspiral phase of binaries
merger phase of binaries
post merger phase of binaries
isolated white dwarfs
In flat region of spacetime with a group of motionless test particles lying in a plane, as a gravitational wave passes through the particles along a line perpendicular to the plane of the particles
Area enclosed by the test particles is conserved
Two types of polarisations of the particle's movements is observed
particles can never return back to their original state
there is motion along the propagation
Speed of gravitational waves=
0.5 of light speed
supersonic speeds
sound speed
Light speed
