hi Bartek, You might want to try cosmo-pl at cosmo.torun.pl - the list hasn't been used much, but there are many AGN people on it (mostly from CAMK Wawa), and this is probably a good practical research question. It's also a good test for them. ;) Of course, możesz pisać w (pl), i ewentualnie podpisać coś jak "doktorant, CA-UMK" po "Bartek" żeby jest więcej szans mieć odpowiedź, bo chyba (jeszcze ;) wszyscy nie Ci znają. pozdr boud On Fri, 12 Nov 2004, Bartosz Lew wrote:

Hi everybody,

I'm interested if anybody has some quick nice references or ideas regarding - as in the subject - what the velocities in relativistic jets can be - what this can depend on from theoretical considerations/modelling?

The bottom line is, can we have some constrainst on these velocities from models, or models and ovservations (if so - what observables are needed) and what this can depend on ?

Is it very bad to assume that these can span from say some arbitrary value to one in \beta space with flat statistical distribution ?

Can we have some hints on this distribution ?

Motyl, I could use your help here ? I don't have time for getting through tons of papers.
