Active galactic nuclei: sources for ultra high energy cosmic rays
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst, in the radio galaxy Cen A which is pushed up in energy by the shock of a relativistic jet. ...
The origin of matter at the base of relativistic jets in active galactic nuclei
(Multidisciplinary Digital Publishing Institute, 2020-07-18)
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood. Relativistic jets are likely produced by the accretion of matter and ...

Searching for active galactic nuclei among unidentified INTEGRAL sources
(2011)
We report on a new method to identify active galactic nuclei (AGNs) among unidentified INTEGRAL sources. This method consists of cross-correlating unidentified sources listed in the fourth Imager on Board the INTEGRAL ...
Cosmological mass transport on galactic nuclei and the growth of high-z quasars
(Wiley-VCH Verlag, 2019)
By using cosmological hydrodynamic simulations, we have studied how supernovae (SNe) and active galactic nuclei (AGN) feedback affect the mass transport (MT) process in high-redshift (z ∼ 6) galaxies and what the consequence ...
