GRAWITA – GRAvitational Wave Inaf TeAm



This is the official GRAWITA (GRAvitational Wave Inaf TeAm) web page. Starting from mid September 2015, the Gravitational Waves detector advanced-LIGO became operative. In autumn 2016, another GW detector, advanced-Virgo will start its science runs. Our team GRAWITA is carrying out follow-up observational campaigns in the optical/NIR bands of the GW trigger observable with the VST, VLT, LBT, TNG, REM ground-based facilities.

The Memorandum of Understanding (MOU), signed in May 2014, establishes a collaborative effort among the Laser Inter- ferometerGravitational-Wave Observatory (LIGO) and LIGO Scientific Collaboration, the European Gravitational Observatory and Virgo Collaboration (EGO/Virgo), and Project of Istituto Nazionale di Astrofisica (INAF) in order to participate in a program to perform follow-up observations of gravitational wave candidate events with the sharing of proprietary information.

Since May 2015, an INAF team is working to make possible a prompt observational campaign to GW alert from LIGO/VIRGO collaboration (LVC). In fact, the MoU provide the possibility of accessing to key information (time and position in the sky) of all the gravitational waves (GW) detections from LVC. To this aim, GRAWITA has several actived proposals to LBT, TNG, VLT, ASIAGO, SRT etc. To improve the chances of accessing to observational time, it has been build up an extended network of international collaborations.

In this site, it is possible to find some information about the observational facilities that can be used to perform the search, characterization and follow-up observation just after the trigger on GW detection provided by LVC. Further, some key scientific by-products project are also collected in this website. This make clear that there will be also a guaranteed outcome of this research: in fact the search for transients in wide field images will provide the basis for a number of studies related to the Time Domain Astronomy.
