    Area of Science:

    • Astrophysics
    • Cosmic Jets
    • Galaxy Evolution

    Background:

    • Astrophysical jets are enormous linear structures originating from stars and galaxies.
    • Galactic jets are among the largest structures in the universe, exceeding galaxy size by 100 times.
    • Stellar jets consist of ionized gas moving at hundreds of kilometers per second.

    Purpose of the Study:

    • To define properties of extragalactic jets.
    • To understand the composition and velocities of extragalactic jets.
    • To constrain models of central power sources in galaxies and quasars.

    Main Methods:

    • Analysis of jet properties through interaction with the ambient medium.
    • Characterization of extragalactic jet composition (relativistic particles, magnetic fields, plasma).

  • Estimation of initial outflow velocities and energy flux.

    • Main Results:

    • Extragalactic jets contain relativistic particles, magnetic fields, and plasma.
    • Outflow velocities can be relativistic, averaging several thousand kilometers per second.
    • Energy flux can exceed 10(46) ergs per second.

    Conclusions:

    • Jet properties derived from ambient medium interactions are key.
    • These properties provide essential constraints for models of galactic and quasar power sources.
    • Understanding astrophysical jets is crucial for comprehending extreme cosmic phenomena.
