RESUMEN Obtenemos limites para el flujo de rayos c6smicos en AGNs investigando los mecanismos de aceleraci6n en un ambiente activo y considerando la propagaci6n de rayos c6smicos desde los AGNs hasta nuestra Galaxia. Es comiinWente aceptado que el flujo observado, con energias inferiores a 1019 eV, es de origen Galactico; por consiguiente, el flujo que proviene de todos los AGNs debe ser mucho menor que el flujo observado. Demostramos que luminosidades de rayos c6smicos con valores entre 10 y 1046 ergs/s son permitidas por modelos de, ley de potencia admisibles en AGNs. Por tanto, el flujo de rayos c6smicos intrinseco puede ser suficiente para afectar significamente el gas circundante, el cual forma las regiones de lineas anchas y lineas estrechas. ABSTRACT We obtain constraints on the cosmic ray flux in AGNs by investigating the acceleration mechanisms in an active environment and by considering the propagation of cosmic rays from AGNs to our Galaxy. At energies below 1019 eV, the observed flux is thought to be mostly of Galactic origin; therefore, the flux coming from all quasars must be much less than the observed flux. We show that cosmic ray luminosities at each AGN with values between 10 and 1046 ergs/s are still allowed, for plausible power-law models. Thus, the intrinsic flux of cosmic rays can be large enough to affect significantly surrounding gas in the broad and the narrow line regions of an AGN.
