| Abstract: | The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced
LIGO and Advanced Virgo (GW170817), along with the discovery of the electromagnetic counterparts
of this GW event, ushered in a new era of multimessenger astronomy, providing the first
direct evidence that BNS mergers are progenitors of short gamma-ray bursts (GRBs). Such events
may also produce very-high-energy (VHE, > 100 GeV) photons which have yet to be detected
in coincidence with a GW signal. The Cherenkov Telescope Array (CTA) is a next-generation
VHE observatory which aims to be indispensable in this search, with an unparalleled sensitivity
and ability to slew anywhere on the sky within a few tens of seconds. Achieving such a feat
will require a comprehensive real-time strategy capable of coordinating searches over potentially
very large regions of the sky. This work will evaluate and provide estimations on the number of
GW-CTA events determined from simulated BNS systems and short GRBs, considering both on and
off-axis emission. In addition, we will present and discuss the prospects of potential follow-up
strategies with CTA. |
