The ultra-high energy cosmic rays (UHECR) originate probably from extragalactic sources, e.g., Starburst, Radio Galaxies, and Active Galactic Nuclei (AGNs). In the present work, we obtain the upper limits of the cosmic-ray luminosity of Starburst galaxies. The method described in A.D. Supanitsky, V. de Souza, J. Cosmol. Astropart. Phys. 2013, 023 (2013) and R.C. Anjos, A.D. Supanitsky, V. de Souza, J. Cosmol. Astropart. Phys. 2014, 049 (2014) is a productive tool for obtaining the upper limits of the cosmic-rays luminosity and illustrates techniques to study the origin of UHECR from gamma rays at GeV-TeV. The method has been used with the upper limit on the GeV-TeV gamma-ray flux measured by space and ground instruments, such as Fermi-LAT, VERITAS, H.E.S.S., and MAGIC. It connects a measured upper limit on the integral flux of GeV-TeV gamma-rays and the UHECR cosmic-ray luminosity of a point source. (AU) | |
