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…
A semicoherent resampling method for long-transient gravitational wave searches with applications to subsolar-mass primordial black-hole binaries
Neil Lu, Cristiano Palomba, Ornella J. Piccinni +1
Resampling removes the modeled phase evolution of a frequency-evolving signal, transforming it into a monochromatic one. We introduce a novel implementation for long-transient grav…
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…
Complex frequency evolution of direct waves from binary black hole mergers
Ling Sun, Sizheng Ma, Patrick P. Chen +3
While no signal originating at a black hole's event horizon can reach future null infinity, information about the horizon and its immediate vicinity can be encoded in asymptotic pr…
GW250114 reveals black hole horizon signatures
Neil Lu, Sizheng Ma, Ornella J. Piccinni +2
The horizon of a black hole, the "surface of no return", is characterized by its rotation frequency and surface gravity . A striking signature is that any infalling object…
Statistical identification of ringdown modes with rational filters
Neil Lu, Sizheng Ma, Ornella J. Piccinni +2
Measuring quasinormal modes (QNMs) during the ringdown phase of binary black hole coalescences provides key insights into merger dynamics and enables tests of the no-hair theorem.…
