Tiling strategies for optical follow-up of gravitational wave triggers by wide field of view telescopes

Understand

Binary neutron stars are among the most promising candidates for joint gravitational-wave and electromagnetic astronomy.

• The goal of this work is to investigate the strategy of using gravitational wave sky-localizations for binary neutron star systems, to search for electromagnetic counterparts using wide field of view optical telescopes.
• We examine various strategies of scanning the gravitational wave sky-localizations on the mock 2015-16 gravitational-wave events.
• We propose an optimal tiling-strategy that would ensure the most economical coverage of the gravitational wave sky-localization, while keeping in mind the realistic constrains of transient optical astronomy.
