Intermediate-Mass Black Holes as LISA Sources
M. Coleman Miller (University of Maryland)
TL;DR
This paper discusses how intermediate-mass black holes can serve as detectable sources of gravitational waves for LISA, enabling tests of general relativity in strong gravity regimes.
Contribution
It provides an analysis of IMBH mergers as gravitational wave sources and their potential for testing general relativity.
Findings
IMBH mergers produce detectable gravitational wave signals for LISA.
These signals can be used to test predictions of general relativity.
IMBHs occupy a key mass range for gravitational wave astronomy.
Abstract
Intermediate-mass black holes (IMBHs), with masses of hundreds to thousands of solar masses, will be unique sources of gravitational waves for LISA. Here we discuss their context as well as specific characteristics of IMBH-IMBH and IMBH-supermassive black hole mergers and how these would allow sensitive tests of the predictions of general relativity in strong gravity.
