Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

Equal-arm detectors of gravitational radiation allow phase measurements many orders of
magnitude below the intrinsic phase stability of the laser injecting light into their arms. This is …

In this work, we study the prospect of detecting the stochastic gravitational-wave background
with the TianQin Observatory. We consider sources of both astrophysical and cosmological …

We develop a tool for the analysis of stochastic gravitational wave backgrounds from
cosmological first-order phase transitions with LISA: we initiate a template databank for …

Detecting stochastic background radiation of cosmological origin is an exciting possibility for
current and future gravitational-wave (GW) detectors. However, distinguishing it from other …

Various scenarios of cosmic inflation enhance the amplitude of the stochastic gravitational
wave background (SGWB) at frequencies detectable by the LISA detector. We develop tools …

We present first-order models for tilt-to-length (TTL) coupling in Laser Interferometer Space
Antenna (LISA), both for the individual interferometers, as well as in the time-delay …

Future missions of gravitational-wave astronomy will be operated by space-based
interferometers, covering a very wide range of frequencies. Search for stochastic …

The space-based gravitational wave detector LISA will observe mergers of massive black
hole binary systems (MBHBs) to cosmological distances, as well as inspiralling stellar-origin …

The coupling of an angular jitter into the interferometric phase readout is summarized under
the term tilt-to-length (TTL) coupling. This noise is expected to be a major noise source in the …
