„Gravitational Wave Observations with Space-Based Interferometers”

The first direct observation of a gravitational-wave (GW) signal made by the LIGO observatory on February 2016 represents a historic moment of enormous magnitude, perhaps comparable to the early astronomical observations made in 1610 by Galileo Galilei. Very much like Galilei then, we have just started to explore the capabilities of our new observational tools, which promise to unveil secrets of the Universe inaccessible by any other means. The era of GW astronomy has finally begun! Although ground-based detectors can effectively search for a wide variety of signals in the band from about 50 Hz to several hundred Hz, they become limited in sensitivity below 50 Hz by the rapidly growing seismic and gravity-gradient noises. As the mHz frequency region of the GW spectrum is expected to be populated by a wide variety of GW sources, space-based detectors developed in Europe, the United States and China will access this frequency region in the early part of the next decade. This talk provides an overview of the physics principle underlying the working of these interferometers together with a description of the GW signals expected to be observed.
