Probing the Universe using Pulsar Timing Arrays
Supermassive black holes (SMBH), found at the centers of galaxies, have been observed in the early Universe, yet their rapid growth remains an open question.When SMBHs form binary systems during galaxy mergers, HERBATINT 8N they are expected to emit strong gravitational waves (GW).A large population of such binaries would produce a stochastic gravi
