Query: Tiling strategies for optical follow-up of gravitational wave triggers
  by wide field of view telescopes   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.
Our analysis reveals that the proposed tiling strategy improves the
sky-localization coverage over naive contour-covering method. The improvement
is more significant for observations conducted using larger field of view
telescopes, or for observations conducted over smaller confidence interval of
gravitational wave sky-localization probability distribution. Next, we
investigate the performance of the tiling strategy for telescope arrays and
compare their performance against monolithic giant field of view telescopes. We
observed that distributing the field of view of the telescopes into arrays of
multiple telescopes significantly improves the coverage efficiency by as much
as 50% over a single large FOV telescope in 2016 localizations while scanning
around 100 sq. degrees. Finally, we studied the ability of optical counterpart
detection by various types of telescopes. In Our analysis for a range of wide
field-of-view telescopes we found improvement in detection upon sacrificing
coverage of localization in order to achieve greater observation depth for very
large field-of-view - small aperture telescopes, especially if the intrinsic
brightness of the optical counterparts are weak.
