An update on the development of searches for binaries using LISA

The space based laser interferometer LISA, expected to be operational in the next decades, will be able to probe the millihertz frequency band. This will make it sensitive to a vast array of compact object mergers including the massive black holes or MBHs. These black holes, straddling the intermediate and supermassive types of black holes, have masses extending above a minimum of 1000 Mⵙ. It would be in general important to work on developing the science ground segment to enable the designing of searches for the binaries that LISA will be sensitive to, fitting of multiple diverse sources and the generation of simulated data to test and calibrate such searches. The MBHs are expected to be observable within the LISA band for several weeks to months before they merge, making them excellent candidates for low latency, pre-merger observations. Also, some mergers of MBHs are expected to have electromagnetic counterparts which makes it important to send out pre-merger alerts with sky location information from LISA data analysis to the astronomy community for early detections of such mergers in multiple electromagnetic bands. It would also be important to assess the precision up to which we can measure the parameters of MBHs. In my talk I explore some developments towards the designing of the search for MBHs in LISA data.
