Searching for gravitational wave events counterparts in x-rays by tilting the multiple shells of Wolter-I optics

Le résumé fourni par la source

Current X-ray telescopes have a combination of field of view and angular resolution unsuitable to accurately localize the electromagnetic counterparts of gravitational wave events. This will become increasingly important when the LIGO and Virgo experiments will work at full sensitivity, when the Einstein Telescope observatory will come online, or with the space mission LISA, all in the next decade. With the goal of having a source localization accuracy of tens of arcsec over a ~10 square degrees field of view, together with hundreds of cm^2 effective area, we study how Wolter-I optics can be appropriately modified. We compare the advantages and drawbacks of each optical design, in particular regarding the contribution of stray light.
