Talk	Oral abstract	Title	improving sky localization and amplitude reconstruction of transient gravitational waves by optimal detector topologies
Co-authors	S.Klimenko, G.A.Prodi, G.Vedovato
Abstract	Searches for gravitational wave transient signals profits from a larger number of operating detectors and sites. Here we will discuss the case of the upcoming generation of interferometric detectors and show the potential improvement of performances using non-standard detector topologies. In fact, optimal detector geometries enables a significantly better reconstruction of GW signals with a fewer number of detector sites with respect to the classical right angle "L" shape. In particular, we compare performances of planned and optimal networks that have a great impact for multi-messenger searches: sky coverage and source localization.

Talk	Oral abstract	Title	Sky localization and amplitude reconstruction of transient gravitational waves in future gravitational wave detectors networks
Co-authors	S.Klimenko, G.A.Prodi, G.Vedovato
Abstract	Searches for gravitational wave transient signals profit from a larger number of operating detectors and sites. This presentation focuses on two important characteristics of the network: sky localization and reconstruction of both polarization amplitudes of the GW transient signals. This will be discussed in the framework of the upcoming generation of interferometric detectors, including Advanced LIGO and Virgo, KAGRA and the newly proposed detector in India. In addition, we show a potential improvement in performances by using different site topologies with increased coverage of the GW polarizations.
