This could serve as a good calibration source for the TianQin gravitational wave observatory. Similar configuration of geocentric orbit space-borne gravitational wave detectors have been developed since 2011, [9] [10] and was shown to have favorable properties for observing intermediate-mass and massive black-hole binaries. [10]
Current detectors are only sensitive to the late stages of the coalescence of black hole and neutron star binaries: only the last seconds of the whole process can currently be observed (including the end of the inspiral phase, the merger itself and part of the ringdown).
It is not clear that a starship powered by Hawking radiation can be made feasible within the laws of known physics. In the standard black hole thermodynamic model, the average energy of emitted quanta increases as size decreases, and extremely small black holes emit the majority of their energy in particles other than photons.

MiniGRAIL is highly sensitive in the 2–4 kHz range, suitable for detecting gravitational waves from rotating neutron star instabilities or small black hole mergers. [ 6 ] It is the current consensus that current cryogenic resonant mass detectors are not sensitive enough to detect anything but extremely powerful (and thus very rare ...
In the case of both components being intermediate black holes between 600 and 10 4 solar masses, LISA will be able to detect events up to redshifts around 1. In the case of an intermediate mass black hole spiralling into a massive black hole (between 10 4 and 10 6 solar masses) events will be detectable up to at least z=3. Since little is known ...
The second run, O2, which ran from 30 November 2016 to 25 August 2017, made eight detections: seven black hole mergers and the first neutron star merger. [16] The third run, O3, began on 1 April 2019; it was divided into O3a, from 1 April to 30 September 2019, and O3b, from 1 November 2019 [ 17 ] until it was suspended on 27 March 2020 due to ...
