SEMINARIO:Manel Perucho-Pla

Universidad de Valencia


Titulo:The complex dance between extragalactic jets and host galaxies.

Resumen:

Relativistic extragalactic jets are formed in the vicinity of 
supermassive black-holes in active galactic nuclei (AGN), and they 
propagate through and out of the host galaxy along tens and hundreds of 
kiloparsecs. These jets are among the most powerful astrophysical 
scenarios known, involving time-integrated energies of the order of 
1.e60 erg and powers ranging from 1.e42 to 1.e47 erg/s. On the one hand, 
their supersonic flows trigger strong shocks that propagate through the 
interstellar medium of their host galaxies and eventually through the 
intracluster medium and, on the other hand, they are subject to the 
development of instabilities and to deceleration by entrainment. In my 
talk, I will show that jet evolution is not only affected by its own 
properties, but also by those of the host galaxy, namely gas 
distribution and stellar population. I will also review several results 
that provide evidence for the host galaxy evolution being conditioned by 
the jet passage.
