Detectability of Gravitational-Wave Memory with LISA: A Bayesian Approach

Cropped cornerplots showing parameters estimation of $Q$, $M$, $d_{\mathrm{L}}$, $\iota$, $\alpha$, $\delta$. We plotted the model with memory in green, and the one without in red. The values and uncertainties for parameters indicated on top of the distribution correspond to the memory model. The source parameters are $Q=1.5$ (left) / $Q=2.5$ (right) and [$\chi_{\mathrm{1z}} =\chi_{\mathrm{2z}}=0.7$, $M=5\times10^4 M_\odot$, $d_{\mathrm{L}}=2000$ Mpc, $\iota=\pi/3$, $\varphi_{\mathrm{ref}}=1$, $\psi=0$, $\alpha=0.74$, $\delta=0.29$] Here we used the {\tt NRHybSur3dq8\_CCE} waveform with HM.
