    I Relationship between collision and relaxation

    Can someone explain me (even in poor worda) the relationship between collision and relaxation? I mean, a structure is relaxed when the particles (or stars) inside have frequent collisions? Or not?An elliptical galaxy is a relaxed structure. Can i deacribe the internal stars with a...

    I Why Do Astrophysicists Use νLν in Accretion Disk Emission Studies?

    I'm studying the AGNs for my undergraduate thesis, so i have many reference sources, but for example you can find this type of writing on: Dan Maoz "Astrophysics in a Nutshell". Yes, ##L_{\nu}## is measured in units ##(W/Hz)##.

    I Why Do Astrophysicists Use νLν in Accretion Disk Emission Studies?

    Ok, but why often in the plot of luminosity (where there are ν in abscissa and ν*Lν in ordinate) there is the product between ν and Lν and not only Lν? I don't know if i explained myself better.

    I Why Do Astrophysicists Use νLν in Accretion Disk Emission Studies?

    Why in Astrophysics it is used νLν (where ν is the frequency and Lν is the luminosity at that frequency) in the emission spectrum of an accretion disk?
