title: Model independent reconstruction of SGWBs at LISA
abstract:
In this seminar I discuss the possibility of performing a model independent reconstruction of stochastic gravitational wave backgrounds (SGWB) at LISA. The procedure is based on the possibility of breaking the whole frequency band into a series of smaller intervals (bins). In each bin the signal is then reconstructed with a power law determined through the maximum likelihood estimation method. The result obtained at the end of this procedure is a multi power law which approximates the original unknown signal.
