The studyofgalaxiesthroughhighredshiftsarekeytounderstandingthe
evolutionofgalaxiesthroughcosmictimes.Assuchobjectsareverydifficultto
observedirectly,theyaremainlyexaminedusingempiricallyderivedtoolssuchas
the numerouscorrelationsbetweentheirdifferentparametriccharacteristics,one
of thembeingthelinearrelationshipbetweenfar-infraredandradioemissionin
star-forming galaxies,namedtheFarInfrared-Radio(FIR)Correlation.Although
the correlationwasconsideredtobestableintermsoflinearity,recentworks,
whichincludegalaxiesathighredshifts(0 < z< 6), showedalargedeviation
from thecorrelationinthesesystems.Thegoalofthisdoctoraldissertationis
an examinationofthephysicalprocessesthatleadtothiskindofbehavior.As
