dc.description.abstractThe Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for very-high-energy (VHE) gamma-ray astronomy, with the deployment of tens of highly sensitive and fast-reacting Cherenkov telescopes. It will cover a wide energy range (20 GeV - 300 TeV) with unprecedented sensitivity. To maximize the scientific return, the observatory will be provided with an online software system that will perform the first analysis of scientific data in real-time. This study investigates the precision and accuracy of available science tools and analysis techniques for the short-term detection of gamma-ray sources, in terms of sky localization, detection significance and, if significant detection is achieved, a first estimation of the integral photon flux. The scope is to evaluate the feasibility of the algorithms' implementation in the real-time analysis of CTA. In this contribution we present a general overview of the methods and some of the results for the test case of the short-term detection of a gamma-ray burst afterglow, as the VHE counterpart of a gravitational wave event.en
dc.description.sponsorshipThis work was conducted in the context of the CTA Consortium, and it made use of the CTA instrument response functions provided by the CTA Consortium and Observatory.4 We gratefully acknowledge financial support from the agencies and organizations listed here: http://www.cta-observatory.org/consortium_acknowledgments/. This research made use of ctools, a community-developed analysis package for Imaging Air Cherenkov Telescope data based on GammaLib, a community-developed toolbox for the scientific analysis of astronomical gamma-ray data; and gammapy,5 a community-developed core Python package for TeV gamma-ray astronomy.en
