An Infrared Study of OMC-2

by Michael James Kellen

Under the supervision of Professor Tom Jones

ABSTRACT

Single-dish observations of the quasar 3C 279 from January 1975 to April 1990 were analyzed using the autocorrelation functions of the time series. the decorrelation time was identified with a time scale for variability on the order of a few weeks. The results of the autocorrelation analysis were then compared with two available models of extragalactic jets. the discrepancies were used to identify aspects of jet structure which are more important that was thought in those models.
