| الوصف: | International audience ; Massive black hole binaries (MBHBs) of 105 M⊙−3×107 M⊙ merging in low redshift galaxies (z≤4) are sufficiently loud to be detected weeks before coalescence with the Laser Interferometer Space Antenna (LISA). This allows us to perform the parameter estimation on the fly, i.e., as a function of the time to coalescence during the inspiral phase, relevant for early warning of the planned LISA protected periods and for searches of electromagnetic signals. In this work, we study the evolution of the sky position, luminosity distance, chirp mass and mass ratio uncertainties as function of time left before merger. Overall, light systems with total intrinsic mass Mtot=3×105 M⊙ are characterized by smaller uncertainties than heavy ones (Mtot=107 M⊙) during the inspiral. Luminosity distance, chirp mass and mass ratio are well constrained at the end of the inspiral. Concerning sky position, at z=1, MBHBs with Mtot=3×105 M⊙ can be localized with a median precision of ≃102 deg2(≃1 deg2) at 1 month (1 hour) from merger, while the sky position of heavy MBHBs can be determined to 10 deg2 only 1 hour before merger. However the uncertainty around the median values broadens with time, ranging in between 0.04–20 deg2 (0.3–3×103 deg2) for light (heavy) systems at 1 hour before merger. At merger the sky localization improves down to ≃10−1 deg2 for all masses. For the benefit of the observer community, we provide the full set of data from our simulations and simple and ready-to-use analytical fits to describe the time evolution of uncertainties in the aforementioned parameters, valid for systems with total mass between 105–107 M⊙ and redshift 0.3–3. |
