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…
Impact of Detector Calibration Accuracy on Black Hole Spectroscopy
Mallika R. Sinha, Ling Sun, Sizheng Ma
Systematic errors in detector calibration can bias signal analyses and potentially lead to incorrect interpretations suggesting violations of general relativity. In this study, we…
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.…
