Description
Transient sources are characterized by their unpredictable emission on timescales spanning milliseconds to years. Many transients are known to be emitters of high-energy gamma rays and are also potential sources of non-photonic signals that include cosmic rays, neutrinos and/or gravitational waves. The next generation observatory for very high energy gamma rays will be the Cherenkov Telescope Array (CTA) covering energies from 20GeV to at least 300TeV. With this energy range and one order of magnitude better sensitivity than the current instruments, CTA will reach high redshifts to detect accelerators like black hole or neutron star mergers and it will have access to the shortest time-scale phenomena. The CTA consortium defined several Key Science Projects for the first 10 years, and the study of transient sources is one of them. In my talk I will present the CTA Transients program. Furthermore, I will report on the current activities in the CTA Transients group studying phenomena like Gamma-ray bursts and on multi-messenger studies related to Gravitational Waves and Neutrino events.
