“Perspectives on the Advanced Version of Gravitational Wave Laser
Interferometers”
Michele Zanolin
Assistant Professor Space Physics Department
Embry Riddle Aeronautical University
Research Associate MIT-LIGO Lab
The ongoing and planned data acquisitions from LIGO and VIRGO might
provide the first direct measurements of gravitational wave signals. In
this talk I will review a new perspective on which physical parameters
will be possible to estimate with the current and planned laser
interferometers. I will also discuss the capability of discriminating
among different models of gravitation. The main mathematical tool that
will be used is an expansion of the bias and covariance of a maximum
likelihood estimation of the parameters in terms of signal-to-noise
ratio powers. The higher orders of these expansions, that can be derived
from Dyson-type equations, provide new knowledge with respect to the
standard Fisher Information based error studies. The general
applicability of these expansions will be addressed.
