Accounting for detector calibration uncertainty in black-hole ringdown analysis
Rowina S. Nathan, Shingo Hido, Neil Lu +3
Detector calibration systematics can bias measurements of a remnant black hole's mass and spin, producing spurious evidence against general relativity if unaccounted for. The ringd…
From driven oscillations to free ringdown: a particle plunging into Kerr
Colin Weller, Andrew Laeuger, Fulin Li +5
We show that a ringdown waveform can admit a constant-coefficient quasinormal-mode (QNM) representation while its individual QNM-pole contributions remain driven. To establish this…
Transdimensional inference for gravitational-wave astronomy with Bilby
Hui Tong, Nir Guttman, Teagan A. Clarke +8
It has become increasingly useful to answer questions in gravitational-wave astronomy using transdimensional models where the number of free parameters can be varied depending on t…
