Astrophysical Sources of Low-Frequency Gravitational Waves
Abstract
The first successful detection of gravitational waves (GWs) by ground-based interferometer LIGO announced in 2016, has opened up a new window on the Universe allowing to register catastrophic events involving big masses and strong space-time curvatures. This detection gave also a new boost to the idea of building a space-borne detector (LISA) - sensitive to much lower frequencies (1 mHz - 1 Hz) than ground-based detectors could ever be. Pulsar timing arrays (PTA) are currently searching of GWs at even lower frequencies (1 nHz - 0.01 mHz). In this contribution, I review astrophysical sources of GWs which we expect to register with LISA and PTA.
