Impact of the spherical harmonic mode with memory on parameter estimation for ground-based detectors
Maria Rosselló-Sastre, Sascha Husa, Sayantani Bera +1
We recently presented an efficient and accurate waveform model for the spherical harmonic mode including both the displacement memory contribution and the ringdown oscillat…
Mind the step: On the frequency-domain analysis of gravitational-wave memory waveforms
Jorge Valencia, Rodrigo Tenorio, Maria Rosselló-Sastre +1
Gravitational-wave memory is characterized by a signal component that persists after a transient signal has decayed. Treating such signals in the frequency domain is non-trivial, s…
A waveform model for the missing quadrupole mode from black hole coalescence: memory effect and ringdown of the spherical harmonic
Maria Rosselló-Sastre, Sascha Husa, Sayantani Bera
In this paper we describe a model for the spherical harmonic mode of the gravitational wave signal emitted by the coalescence of binary black holes, in particular,…
Enhancing Gravitational Wave Parameter Estimation with Non-Linear Memory: Breaking the Distance-Inclination Degeneracy
Yumeng Xu, Maria Rosselló-Sastre, Shubhanshu Tiwari +5
In this study, we investigate the role of the non-linear memory effect in gravitational wave (GW) parameter estimation, particularly we explore its capability to break the degenera…
