GW231123 ringdown: interpretation as multimodal Kerr signal
Harrison Siegel, Nicole M. Khusid, Maximiliano Isi +1
GW231123 is a short-duration, low-frequency gravitational wave signal consistent with a binary black hole coalescence and dominated by the merger-ringdown regime due to the high ma…
Probing the ringdown perturbation in binary black hole coalescences with an improved quasi-normal mode extraction algorithm
Keefe Mitman, Isabella Pretto, Harrison Siegel +9
Using gravitational waves to probe the geometry of the ringing remnant black hole formed in a binary black hole coalescence is a well-established way to test Einstein's theory of g…
Analyzing black-hole ringdowns II: data conditioning
Harrison Siegel, Maximiliano Isi, Will M. Farr
Time series data from observations of black hole ringdown gravitational waves are often analyzed in the time domain by using damped sinusoid models with acyclic boundary conditions…
Black Hole Spectroscopy for Precessing Binary Black Hole Coalescences
Hengrui Zhu, Harrison Siegel, Keefe Mitman +14
The spectroscopic study of black hole quasinormal modes in gravitational-wave ringdown observations is hindered by our ignorance of which modes should dominate astrophysical signal…
The Ringdown of GW190521: Hints of Multiple Quasinormal Modes with a Precessional Interpretation
Harrison Siegel, Maximiliano Isi, Will Farr
GW190521 is a short-duration, low-frequency gravitational-wave signal in the LIGO-Virgo catalogue. The signal is consistent with the ringdown and possibly some of the inspiral-merg…
Revisiting Thermal Charge Carrier Refractive Noise in Semiconductor Optics for Gravitational-Wave Interferometers
Harrison Siegel, Yuri Levin
The test masses in next-generation gravitational-wave interferometers may have a semiconductor substrate, most likely silicon. The stochastic motion of charge carriers within the s…
A High Efficiency Photon Veto for the Light Dark Matter eXperiment
Torsten Åkesson, Nikita Blinov, Lene Bryngemark +28
Fixed-target experiments using primary electron beams can be powerful discovery tools for light dark matter in the sub-GeV mass range. The Light Dark Matter eXperiment (LDMX) is de…
