Scientific paper
This proposal is aimed to detect optical emission from one of the most intriguing astronomical object ever found in the sky: the newly discovered binary system harbouring two pulsar {PSR J0737-3039A and PSR J0737-3039B}. This is the first double-pulsar system ever detected {Burgay et al. 2003; Lyne et al. 2004} and it provides a wonderful laboratory for the study of relativistic gravity and gravitational radiation. Moreover, for the first time, it offers the opportunity to probe the magnetosphere and the local environment of a neutron star. There is indeed evidence of strong interactions between the energy released by one pulsar and the magnetosphere of the other. Our team is now carrying out a multi-wavelength project to understand the nature of the occurring interactions and the energy budget of the system. In particular, while radio observations will continue to survey the object, X-ray observations with Chandra have been already allocated. Here we ask for deep ACS-HR observations to catch the optical emission from the system. These observations will firstly estimate the optical nonthermal flux, and, once combined with radio and X-ray fluxes, will give us unique insights into the physics of the relativistic wind interactions within the system.
